Dear Colleagues,

I am very pleased to announce that Dr. Ruth Steiner, Associate Professor in the Department
of Urban f Regional Planning (URP) was named the CMS's associate director, effective July
1, 2009. Dr. Steiner has been instrumental in getting the center off the ground, and also
S in establishing strong collaborative activities between the Department of Civil F Coastal
C Engineering (CCE) and URP. In her new role Dr. Steiner will be primarily responsible for the
center's educational activities. Additional information regarding Dr. Steiner's new appointment
is provided on page 3.

With CMS entering its third year of operation, five of the projects selected during the center's
first request for proposals are scheduled to be completed by December 2009. These projects
deal with a variety of topics: the tradeoffs and costs of congestion in supply chains, large
scale evacuations, congestion pricing, signal timing optimization F Florida's Central Data
Warehouse (CDW). Look for the final reports of those projects at our Web site http://cms.ce.ufl.
edu/research/completed projects.php. We just completed our third-year call for proposals,
where 18 pre-proposals were submitted to the CMS and nine chosen to submit full proposals
for further consideration. The results of the final selection process will be announced by mid-
February 2010.

The CMS has just started work on a research project funded by the Florida Department of
Transportation (FDOT) to study managed (High Occupancy Toll HOT) lane operations (PI:
Yafeng Yin). During this two-year project, UF researchers will analyze managed lanes demand
behavior, compare time-of-day vs. dynamic managed lanes, evaluate the capacity of managed
lanes, and assess the interactions between ramp metering and toll lane operations. The research
will be based on data from the 1-95 Express lanes in Miami, Fla., one of FHWA's Urban
Partnership Agreement Projects.

Our transportation graduate program continues to grow, and there are currently 69 students
3 affiliated with the CMS. The first graduate of the concurrent degree in transportation
engineering and urban planning (Mr. Benito Perez) is now employed as a transportation
engineer at the Hampton Roads Transportation Planning Organization in Chesapeake, Va.
3 The concurrent degree program continues to gain momentum, as more students become
aware of the benefits it offers and the opportunities available to them after graduation. Our
Transportation Research Internship Program (TRIP) has proven to be an excellent program for
c encouraging undergraduate students to enter the transportation graduate program. Several of
our interns continue to work on research projects after their internships have ended and plan
o to eventually attend graduate school.

This summer, the CMS co-sponsored a Workshop on Roundabouts held in Orlando, Fla.
8-0 Speakers included some of the best in the area of roundabout design and operations. This fall,
we also co-sponsored the second symposium on congestion mitigation strategies and a lunch
for alumni and friends of the UF Transportation Research Center (TRC). The event included
10-1i Congressman John Mica (R-FL), who joined us via video conference from Washington, D.C.;
Laura Kelley of the Orlando-Orange County Expressway Authority; Steve Arrington of the
1 1 Jacksonville Transportation Authority; Grady Carrick of the Florida Highway Patrol; and Teresa
12- 13 Scott of Gainesville Public Works. Our lunch speaker was UF Professor Emeritus Kenneth
S-1- 1
S In this issue of the CMS newsletter, you will find additional information about several of these
activities, as well as a QFA article with Ms. Linda Watson, CEO of LYNX, also known as the
1 -1 Central Florida Regional Transportation Authority. As always, we welcome suggestions and
hope to collaborate with you in the near future. Read on!

I Sincerely,

Lily Elefteriadou, Ph.D.
CMS Director

Abstract: One of the main goals in a transportation planning
process is to achieve solutions for two classical problems: the

traffic assignment problem, which minimizes the total travel
delay among all travelers, and the toll pricing problem which
settles, based on data derived from the first problem, the tolls
that would collectively benefit all travelers and would lead to a
user equilibrium solution. Acquiring precision for this framework
is a challenge for large networks. In this article, we propose an
approach to solve the two problems jointly, making use of a
Hybrid Genetic Algorithm for the optimization of transportation
network performance by strategically allocating tolls on some
of the links. Since a regular transportation network may have
thousands of intersections and hundreds of roads, our algorithm
takes advantage of mechanisms for speeding up shortest-path

Characterizing the Tradeoffs and Costs Associated with Transportation

Congestion in Supply Chains (CMS Project #2008-004)

Department of Industrial Et Systems Engineering
University of Florida

The design of a supply chain network requires
considering numerous decision factors, including the locations
of facilities (plants and distribution centers), the assignment of
customers or markets to supply facilities, production and storage
levels at facilities, and the timing and quantities of shipments
between facilities. These decision factors serve as primary drivers
of operations costs in supply chains, and the interdependence of
these decisions and the associated tradeoffs lead to a high level
of complexity. For example, building a large number of facilities
close to customer markets may result in low transportation costs
for finished goods, but the associated facility costs and required
inventory investment might make this an unattractive option. At
the other extreme, while having only a few facilities may reduce
facility and inventory holding costs, the associated transportation
costs for finished goods may be prohibitive.
Classical supply chain design approaches have
considered these complex interactions and tradeoffs between
facility, transportation, and inventory holding costs in the
development of a supply chain's architecture. These classical
approaches typically assume a particular transportation cost
structure that accurately determines projected transportation
cost based on the frequency and quantity of deliveries between
facilities and markets. These approaches have, therefore, ignored
the important (but complicated) way in which traffic congestion
influences supply chain performance. Traffic congestion leads to
increased transportation-related costs and increased delivery lead
times, which, in turn, increases the required system inventory
investment for meeting desired customer service levels. Thus,
ignoring the effects of traffic congestion in supply chain design
decision-making can lead to inaccurate cost projections and
suboptimal supply chain network designs.
Accounting for the impacts of traffic congestion
on supply chain design requires simultaneously considering
the individual decisions made by different, independent
decision makers. This leads to the consideration of two kinds
of competition in supply chains: competition for product sales
and competition for limited transportation capacity. The former
type of competition is resolved in the marketss, where a market
equilibrium price and a supplier's sales combine to determine the

supplier's market revenue. The latter type of competition interacts
with the former (indirectly, via the implied costs) to determine
the equilibrium supply quantities firms will send to markets.
We apply the tools of Game Theory and Operations Research in
order to develop mathematical decision models that account for
decentralized decisions in a competitive environment.
Our goal in this research is to understand how traffic
congestion costs and effects, which are not separable, influence
supply chain location and distribution decisions, i.e., strategic
supply chain designs. We have thus developed mathematical
models for distribution and location planning decisions in supply
chains that explicitly account for traffic congestion costs and
impacts. As part of our research, we exercised these models
computationally, via numerical tests, to gain additional insight
into how traffic congestion qualitatively affects optimal decision-
making in supply chains.
We first studied a competitive facility location and
market-supply game with multiple identical firms competing in
different markets in a congested distribution network. As a result
of their location and quantity supply decisions, firms are subject to
location-specific transportation costs, convex traffic congestion
costs and fixed facility location costs (convex congestion costs
increase at an increasing rate in the congestion level, as one
would expect in practice). First, we study the supply quantity
decisions for a firm when the location choices of the firms are
identical. An oligopolistic Coumot game is analyzed to determine
a Pure Nash Equilibrium (PNE) for these quantity decisions, and
we provide analytical results on the effects of traffic congestion
costs on the equilibrium quantities flowing from supply facilities
to markets. (A Coumot game is one in which the equilibrium
price in a market is inversely proportional to the total market
supply; a Pure Nash Equilibrium is a solution in which each
player's strategy is deterministically defined, and no player can
be unilaterally better off by deviating from the solution.) We next
focus on the location decisions of the firms. As firms are identical,
firms will choose identical facility locations, and we therefore
study the optimal location decisions for any individual firm.
We then study a set of heterogeneous competitive firms
considering the location of facilities at a set of candidate locations

4 CMS FALL 2009

in order to serve a set of markets. In this case, each firm incurs
firm-specific transportation costs, as well as convex congestion
and fixed location costs as a result of location and distribution
volume decisions. The unit price in each market is a linear
decreasing function of the total amount shipped to the market by
all firms; that is, we consider an oligopolistic Coumot game and
analyze the two-stage Nash Equilibrium. This problem is referred
to as the location-supply game, or competitive location game,
and we first study the firms' market-supply decisions for given
facility locations, i.e., the game's second stage. We formulate
the problem of finding the equilibrium supply quantities as a
so-called variational inequality problem and provide a solution
algorithm for determining an equilibrium solution. Then we focus
on the location decisions, i.e., the game's first stage. We provide
rules to obtain a dominant location matrix, and use these rules
in a heuristic solution approach to search for an equilibrium
location matrix.
Our work models traffic congestion costs endogenously
and has provided analytical results on how traffic congestion
costs affect equilibrium supply quantity decisions. Increased
traffic congestion hinders efficient use of the distribution
network, as firms may choose to supply a market from multiple,
distant, decentralized facilities. Moreover, the results of our
numerical studies characterize the effects of congestion on
facility location decisions as well. In our numerical studies, we
illustrate how a continuous increase in traffic congestion cost
can drive firms out of markets and out of business. Furthermore,
we highlighted a counter-intuitive result in our numerical studies

by showing that, under Coumot competition, firms may, in some
scenarios, actually increase their profit levels when they ignore
congestion-based competition. That is, when all firms consider
congestion costs, in equilibrium, individual firms supply less to
markets than they would in the absence of these costs. At this
equilibrium point, no firm is willing to unilaterally deviate from
the equilibrium solution and increase their supply quantity, as
the increased revenue they would see would not outweigh the
increased congestion cost. However, if all firms were to ignore
their traffic-congestion-related costs, they would then all
choose to supply greater quantities to markets, and the resulting
increased revenue can, in certain cases, outweigh the increased
traffic-congestion-related costs. We note that this result assumes
that all individual firms make the same choice to either consider
or ignore congestion-related costs. When competitors compete
over more than one resource, e.g., market price and congestion in
our case, analyzing which of these is the primary driver of profit
serves as an interesting problem for further study.
Our results document the negative effects of traffic
congestion on firms. As a result, it is possible that firms may
be willing to cooperate with government agencies to reduce the
burden traffic congestion places on a firm's cost structure. It is
even possible that firms may cooperate with each other to mitigate
traffic congestion, and, thereby reduce the negative effects of
traffic congestion. Studying such traffic-congestion-mitigation
policies, with mathematical bases, remains a promising research

About 50 people attended the 2"' Congestion Mitigation
Strategies Symposium co-sponsored by the CMS on Nov.
6, 2009. The symposium was held in conjunction with
the 100 Years of Gator Engineering celebration and with
the TRC Alumni ft Friends Lunch. Symposium guest
speakers included Congressman John Mica (R-FL) via
videoconference from Washington, D.C.; John Arrington
from the Jacksonville Transportation Authority; Chief
Grady Carrick of the Florida Highway Patrol; Laura Kelley
of the Orlando-Orange County Expressway Authority and
Teresa Scott of Gainesville Public Works.

This was Congressman Mica's second time as a guest
speaker at one of the CMS's symposiums. During his
videoconference, he encouraged researchers at UF and the
public alike to provide his office with comments, as the
new transportation bill is being written and debated. The
congressman isthe ranking memberoftheTransportation and
Infrastructure Committee and is extremely knowledgeable
on transportation issues affecting our nation and the state
of Florida. Transportation faculty at UF were pleased the
congressman took time off from his busy schedule to join
the symposium via videoconference.

"Congressman Mica's continued engagement with our
center and his willingness to participate in our activities is
very telling of his commitment to transportation," said Lily
Elefteriadou, professor and director of the TRC and CMS.
"He is very familiar with the transportation issues Florida
faces, as well as those at the national level. We appreciate
his insights into future research directions, and we hope he
can continue to interact with our students and researchers."

Elefteriadou was also pleased with the presentations of
the other guest speakers/panelists. She said the speakers
are leaders in the transportation community who provide
unique perspectives into congestion mitigation issues. "They
did a wonderful job of describing transportation congestion
problems and solutions they implemented," she said.

The symposium was well attended by students, transportation
professionals, residents from the local Gainesville, Fla., area


and representatives from other transportation affiliated
centers at UF, such as Janet Degner, director of the Florida
Transportation Technology Transfer (T2) Center.

"Mica's involvement the second time around illustrates
his continued support and interest in what the CMS UTC
is doing," Degner said. She added that the transportation
symposium featured a well-rounded program with excellent
speakers who were asked a number of pertinent questions
by the audience. She also hopes future events will be
broadcast live via Elluminate or other webcasting tools as
the topics the CMS presents would benefit many in Florida
and nationally.

Genesis Harrod, a graduate student in UF's transportation
and urban planning concurrent-degree program attended
the symposium. She said she left the event feeling

"1 greatly value the wealth of information presented at
the CMS Symposium," Harrod said. "It provided a window
into various aspects of the transportation profession and
presented different approaches to finding transportation
solutions. 1 look forward to sessions to come."

The CMS and the Transportation Research Center (TRC) at
UF wish to thank all the guest speakers for their excellent
contributions to the symposium. All presentations are

6 CMS FALL 2009


Alumni and friends of the UF Transportation Research Center (TRC) gathered on Nov. 6, 2009, for a lunch in honor of
the center's long-standing legacy as the hub for transportation research at the University of Florida. The lunch was held
in conjunction with the UF College of Engineering's 100th year celebration activities. The TRC is the "umbrella" center
that houses other transportation programs and centers such as the CMS. Former UF transportation alumni and current
students, faculty and staff at UF attended. Professor Emeritus Kenneth Courage, a 38-year veteran of the Department of
Civil Ft Coastal Engineering at UF, was the honored guest speaker at the lunch.

"1 was very glad that Ken agreed to talk during our luncheon because he is one of the leaders in our profession and has
been the leading force behind the TRC for many years," said Lily Elefteriadou, director of the TRC and CMS. "This was
also a wonderful opportunity to reconnect with recent alumni and to get acquainted with those who graduated before 1
arrived to UF."

UF Associate Professor Scott Washburn, a transportation program faculty member in the Department of Civil Ft Coastal
Engineering, has been with TRC for the past 10 years. He has seen many students graduate from the program, and he also
knows Courage well. He was also glad that Courage was chosen to be the honored guest speaker.

"Professor Ken Courage's presentation on the history of the TRC was an informative and humorous retrospective of the
TRC," Washburn said. "The lunch also provided a great opportunity to reconnect with former students."

During Courage's presentation, he recounted some of the more memorable anecdotes of years past. And as for the
academic and research endeavors of the TRC, he believes it will continue to grow strong.

"We've had some excellent faculty and some memorable students in the past 38 years," Courage said. "I'm confident that
the people we have now will continue our tradition as one of the nation's leading transportation research and educational

Becoming a transportation engineer was not in the cards for this UF
professor, but graduate school changed all that, transforming him into
the passionate teacher and researcher he is today.

Living in a hustling and bustling city of more than four million
people, crowded with every form of transportation imaginable, he
relied mostly on the city's bus system for his local travel. He did
not own a car and did not know how to drive one. Little did Siva
Srinivasan know that one day, he would be a faculty member in a
major research institution in the United States, figuring out ways
to mitigate the traffic congestion woes affecting most Americans.

Srinivasan, an assistant professor of transportation engineering in
the Department of Civil Et Coastal Engineering at the University
of Florida, arrived at UF in 2005. He is the youngest member of
the department's transportation faculty and specializes in travel-
demand modeling and travel-behavior analysis, and has also
started working in the area of transportation safety. Srinivasan
teaches a class on urban transportation planning, which is
attended by both graduate and undergraduate students. He also
teaches a graduate course on discrete-choice modeling.

Srinivasan is from Chennai, (formerly known as Madras) in
India. Srinivasan's hometown is India's fourth most populous

metropolitan area, located on its southeastern coast in the state
of Tamil Nadu. It's well-known for its long beaches, fascinating
temples, great food and a strong IT manufacturing and services

"1 had not traveled much within India, and air travel was not
very common," Srinivasan said. "The first time 1 ever got on an
airplane, I flew from Chennai all the way to Austin, Texas, to go
to graduate school. It's kind of interesting when you've never
flown, and suddenly, you are on a flight for almost a day and a

That very long flight from Chennai in 1999 took Srinivasan to The
University of Texas at Austin, where he had been accepted into
the master's degree program in civil engineering, specializing in
transportation. Although he had been exposed to this discipline
during his undergraduate studies in civil engineering at the Indian
Institute of Technology (lIT) in Chennai, a career in transportation
was not necessarily in the cards at that point in his life. It was
only when he began to contemplate graduate studies that he

8 CMS FALL 2009

thought of transportation engineering as a possibility. "There
were so many factors that influenced my choice of an area of
specialization in graduate school, including the funding available
for international students," Srinivasan said. "But once 1 got into
graduate school, into transportation, 1 started liking it very much.
I'm very happy about my career choice."

While at UT, his interest for transportation flourished. He was
mentored by professor Kara Kockelman and worked on analyzing
the economic impacts of highway-bypass roads for his thesis. In
2001, Srinivasan was accepted into the doctoral program in civil
engineering at UT. His doctoral adviser was Professor Chandra
Bhat, well-known for his work in travel-demand modeling and
travel-behavior analysis. In fall 2004, Srinivasan completed
his dissertation on incorporating household-interactions in
activity-based travel-demand models. Today, he is a full-
fledged transportation-engineering expert, passionate about
the applicability of mathematics to traveler behavior, demand
modeling, urban planning and safety issues.

"I am primarily interested in figuring out how travelers behave,
how their behavior changes depending upon the modifications
we make to the transportation and urban systems, and how we
can quantify all these using mathematical techniques," Srinivasan
said. "At the same time, I keep in mind that all the equations
are ultimately to help create a safe and efficient transportation

Srinivasan is an advocate for interdisciplinary collaboration,
particularly between transportation engineers and urban planners.
According to him, planners think primarily about policy issues
and the "big picture," whereas engineers focus on quantitative
problem-solving and the "nitty-gritty" details. The collaboration

can facilitate a holistic approach to solving the urban problems.
Srinivasan has already established strong research collaboration
with the Department of Urban Et Regional Planning at UF.

"Students should have exposure to other disciplines," Srinivasan
said. "They should understand that there are other people who
use different tools to address similar problems or even look at
the same problems from very different perspectives." Srinivasan
is excited that transportation-engineering and urban-planning
students at UF get to extensively interact by taking classes in
each other's departments. The need to facilitate a more formal
interdisciplinary study lead him and his colleague, Ruth Steiner,
an associate professor in the UF Department of Urban Et
Regional Planning, to create the concurrent-degree program in
transportation engineering and urban planning. Srinivasan thinks
the program will make students "bilingual" in the spoken language
as well as mathematics when dealing with urban problems.

Srinivasan firmly believes the transportation program at UF is
exemplary. "The quality of the transportation program at UF is
first-rate," Srinivasan said. "It is a fantastic program, which has
been growing significantly. Our students are highly motivated
and are doing very well." He also likes that the group is diverse
and international.

Looking ahead, Srinivasan has plans to continue his work on
understanding activity-travel behavior and creating better
ways to forecast travel demand. He also plans to continue his
collaborations with the Florida Department of Transportation
(FDOT) to implement his research findings. "I don't want my
efforts to remain only as research publications," Srinivasan said.
"I'm interested in helping the profession by taking advanced
methods into the practice."

Institute for Mobility, Activity and Participation (1-MAP)

Located within the College of Public Health and Health
Professions at the University of Florida, the Institute for
Mobility, Activity and Participation (1-MAP) was formed
earlier this year to support increased driving-related
research that expanded beyond projects in older driver
safety. The National Older Driver Research Ft Training
Center (NODRTC) previously supported the research at the
University of Florida. 1-MAP is now the umbrella under
which all research related to driver safety and mobility will
be conducted.

"We established 1-MAP in 2009 to reflect our focus on
mobility and transportation through the lifespan, and to
bring together professionals and students interested in this
area," said Sherrilene Classen, Ph.D., MPH, OTR/L, director
of 1-MAP.

The goal of 1-MAP is to conduct driver safety research
related to all age groups; study the use of alternative
transportation options, such as use of scooters or buses;
and personal mobility, such as getting around at home
and walking. Within 1-MAP, researchers will execute these
activities as a means to preserve, promote and improve
independent, safe and appropriate mobility for individuals
and within populations.

Co mmmuiymobiity~ u ~mmmi~

"There is a significant need to study all age groups, and we
are already engaged in projects that fall outside the scope
of research on aging drivers," Classen said. "For example,
we are studying driving safety issues of soldiers, of all ages,
returning from the wars in Iraq and Afghanistan."

Currently, researchers at 1-MAP are engaged in projects
related to the driving issues of people with seizure disorders
such as epilepsy, traumatic brain injury/post traumatic
stress disorder/depression, Parkinson's disease and patients
undergoing deep brain stimulation.

"We are also exploring the relationship of personality (for
example extroverts vs. introverts) to driving behaviors and
driving performance," Classen said. "Future plans are that
this research will extend beyond older drivers."

1-MAP has pending or funded proposals, which include:
1) a study on transportation planning concerns (for

What did you like most about working on your project?
I liked learning how to read C# code and learning a lot about all types of interchanges.
What did you like most about TRIP?
I liked doing the presentation on the projects.
Is graduate school in your future?
I will have four graduate classes already done by the end of the fall semester and have
already applied, so hopefully, yes.
What are your hobbies?
I like being on the Steel Bridge Team; watching football, baseball, and basketball;
playing sports; and cooking. Go Gators!

CLASSIFICATION/MAJOR: Junior, civil engineering

CLASSIFICATION/MAJOR: Junior, civil engineering
TRIP ADVISER: Yafeng Yin, Ph.D., assistant professor
PROJECT TITLE: Robust Signal Timing for Arterials using day-to-day Demand Variations and
NCHRP 3-96 Analysis of Managed Lanes on Freeway Facilities

What did you like most about TRIP?
1 really enjoyed getting to know Dr. Yin and some of his graduate students (Lihui Zhang in
particular) and what projects they were researching. 1 also enjoyed the summer transportation
seminar series so that 1 could also learn what the other interns, graduate students and
professors were working on. It also gave me a great insight into what graduate school may be
like for me, and what 1 could expect to do when 1 work on a research project.
What did you like most about working on your project?
For the first project, 1 really enjoyed working with CORSIM and seeing how transportation
engineers simulate roadway conditions and signal plans when they do not have the ability to
test them in the field. For the second project, 1 really enjoyed the freedom 1 had in exploring
all the High-Occupancy Toll (HOT) lanes that are currently in use in the U.S. and seeing how
different each facility is managed and tolled. Each situation was really unique and had very
innovative ideas and technologies to improve tolling and hopefully encourage carpooling.
Is graduate school in your future?
1 do not know for sure yet, since 1 have about a year to apply, but this experience has
definitely helped me to understand what 1 could be doing in graduate school and whether 1
could see myself in that position.
What are your hobbies?
1 really enjoy reading, running, and working with UF's Habitat for Humanity club.

What was your career path to your current position?

1 started my career at the Fort Worth Transportation Authority
as an Administrative Assistant to the General Manager. After
three months on the job, he approached me about learning
all aspects of transit with the end goal of running a transit
system one day. He explained that there would be a large
number of retiring General Managers, creating a leadership
void. He believed that 1 had the skills and potential for running
a system. 1 liked the idea and by the time 1 left the agency, 1
had either worked in, or been exposed to, every department
and function at the transit system. 1 even drove a bus on every
route in the city in training! That kind of practical experience
in all areas of transit prepared me for the role 1 currently have
as CEO at LYNX.

What has been the most rewarding experience of your career?

The Transportation Research Board (TRB) Executive Committee
elected me Chair two years ago, and that is something I'm really
proud of. The people who elected me are my peers and nothing
reinforces the feeling of confidence like being recognized by
your peers. The TRB is one of, if not the most, distinguished and
recognized organizations for transportation research in North
America. It is respected worldwide. Their multi-modal work
has helped me learn so much about all forms of transportation
at a time when transportation is at the top of the regional and
national agenda. It is has been a truly rewarding adventure.

What is the most challenging aspect of your job?

1 fight the love affair with the automobile every day. 1 also
compete for attention from local governments that already
have overloaded agendas. That takes patience, relationship-
building and perseverance.

What are the major transportation challenges in Florida?

There are three very big transportation issues that need to be
addressed: congestion, dedicated funding for transportation
and the idea that building more roads will cure all our
transportation ills. Many cities around the country are
significantly ahead of us in dealing with congestion. They have
made considerably more progress than we have on local rail
projects that ease congestion and funding issues that support
transit. We can't continue to lag behind places like Atlanta,
Dallas and Portland in providing public transit and hope to
stay competitive economically.

The politics of securing dedicated funding has been very difficult,
particularly over the last two years. We must demonstrate

that, as a state, we can successfully deliver commuter rail to
our communities or we won't be able to compete for the
billions of federal dollars available for high-speed rail. As DOT
Secretary Ray Lafood said in Orlando recently, "missing out on
high- speed rail today would be like Florida missing out on the
national highway system when it was built over 50 years ago."

The other major challenge for our state is the belief that more
roads mean less traffic. Los Angeles, Atlanta and Houston are
three of many examples that challenge that belief. Having
said that, 1 have seen a significant shift among important
stakeholders on this issue. FDOT is becoming aggressively
more multi-modal. People moving here from northeastern
cities, where transit is a way of life, are giving us momentum
for non-highway solutions. And there are also many people
who do not want to "pave over paradise" or see us become the
Los Angeles of the east coast.

How can we overcome those?

1 believe what we need most is more active support from
business and political leaders and grassroots education for
everyone. People need to know the facts on what it costs to
build a mile of highway and compare that to the economic and
environmental value of transit. We are making great progress
on this in Central Florida. Orlando Mayor Buddy Dyer has been
tireless in his efforts to get commuter rail (SunRail) on track.
Jacob Stuart, CEO of the Orlando Partnership, has successfully

16 CMS FALL 2009

educated the community and the business leaders about the
importance of commuter rail. The time has never been better
or the future brighter for more transit in Central Florida, as
well as the [whole] state. In the end, building our infrastructure
and improving our transportation network is about jobs and
economic growth, which isn't a hard sell anywhere.

How do the demographic changes in our older population
and the migration trends in Florida impact our transportation

According to the U.S. Census Bureau, by 2030 more than one
in every four residents in Florida will be age 65 and older. We
owe it to them to provide transit options that make economic
and practical sense. At some point, all of them will become
transit-dependent. They need choices on how to get to the
doctor, the supermarket, church or just another friend's home.
Right now, we don't have enough viable choices for them. As
more baby boomers hit the senior circuit, 1 predict the transit
industry is going to hear quite a bit more about this issue.

What is being done on a systems level to provide alternative
transportation options for older adults to ensure independence
in community mobility?

Most transit agencies provide a paratransit service, which
generally is door-to-door van or coach service. However, it
is VERY expensive to operate. The average paratransit ride
on our system costs just under $30 per passenger. LYNX is
developing a community circulator system that will improve
service and reduce costs. It is a hybrid system, something that
combines the best features of paratransit and regular fixed-
route service. Anyone needing service in a designated area can
call two hours in advance, get picked up at their home, and
taken anywhere in the service area or to a fixed-route location
where they can transfer to regular bus service. It's convenient,
safe and very popular with seniors.

ITN America is national non-profit transportation system
designed specifically for our aging population. In many
communities, they allow older people to trade their own
cars to pay for rides, and provide volunteer drivers to store
transportation credits for their own future transportation needs

How do you see the transportation industry, especially transit,
in 10 years and in 50 years?

High-speed rail is the next big thing. It is clean, safe and time-
efficient. Trains can reach 200 miles per hour and higher. But
many metropolitan areas, like Orlando, are going to have to
build the local transit infrastructure, including commuter rail
systems, to make this feasible. That way, when someone takes
the high-speed rail from Miami to Orlando, for example, they
can step off their train, get on commuter rail or another mode,
and be at their final destination in a few minutes without
ever having to use an automobile!

What transportation innovation do you think would be most
beneficial to reduce congestion?

Dedicated bus lanes on major highways and major arterials
would be the most beneficial innovation for transit. If
people sitting in their cars watched the bus run by them in

a dedicated lane and get signal priority at intersections, they
would jump out of their cars and ride transit to work every
day. Another factor that causes congestion is traffic accidents.
Embedded chips are coming on cars and buses that will read
traffic lights and automatically stop vehicles when the light
changes. These same chips will sense pedestrians crossing the
street and automatically stop. It will also steer vehicles to more
efficient routes to get around bottlenecks and on to their final
destination. This will dramatically reduce traffic accidents and
the inevitable congestion they create.

How have technological advancements (in telecommunications,
vehicle technology, etc.) affected the transit industry, and do
you see any such changes due to technology in the foreseeable

Technology advancements are why it's getting easier to
persuade people to give up their cars. We now have GPS systems
that can tell us exactly where our bus is and exactly when
it will arrive. We have mobile and wireless communications
that allow us to have real-time information about schedules
and itineraries at our fingertips. Cashless fare systems, video
cameras on buses, and vehicles that self diagnose mechanical
problems are all here and improving every day. We even have
a machine that we call "The Germinator" that kills viruses in
all of our vehicles so you don't have to worry about getting
sick when you travel. All of these technologies are transferable
to rail systems and the two modes can work hand-in-hand to
make travel easier on people and the environment

What will it take to make the United States a more pro-transit

The straight answer is high gas prices. That could happen
because of increased taxes on gas or increased costs associated
with buying foreign oil. There are discussions about "user
fees" for automobiles, forcing drivers to pay by the mile to
use their cars, but high gas prices are really the surest way
to force people to look at transit. It would be great if that
were to happen, for all the money generated by increased gas
taxes dedicated to public transportation alternatives. We do
know this: The current funding mechanisms can't support
maintenance of our highway system. It's also worth noting that
city planners are pushing dense population centers. In both
cases, public transit won't just be a convenient alternative, it
will the practical solution.

How can the University Transportation Centers (UTCs)
contribute to increased transit use and a more multimodal

The transportation workforce is facing a critical shortage of
well trained and passionate professionals. UTCs are going to
fill that gap. We need more leaders who are better prepared to
address the nation's need for safe, efficient and environmentally
sound transportation of people and goods. UTCs can give us
the research, facts and data that convince policy makers that
there are solutions to the never-ending problem of congestion.
Your input is going to have an immediate and immense impact
on our industry.

D ONA M OSS just celebrated 20 years of
service at the University of Florida. For her dedication, service
and loyalty, she was presented with a commemorative pin and
honored with a reception in the Department of Civil Ft Coastal
Engineering, where she has worked for the past 14 years.

Upon receiving her 20-year-pin, she, made sure to thank the
academy, "because without you, 1 would not be here," she joked.

Moss perhaps has one of the most important and busiest jobs
in the department. She is the one who keeps the contracts and
grants office in excellent shape. Tracking more than 200 grant-
funded projects (and new ones each month), she monitors them
closely, from a project's initiation to its ending date. She has
more than 14 years of knowledge in contracts and grants and is
an excellent resource to the CMS and to the Department of Civil
Ft Coastal Engineering.

"Assisting with the budgets and preparing the proposals is part
of my job and is something 1 have tried to master over the years,"
Moss said. "1 want to make sure that the proposal submissions
go as smoothly as possible for the faculty as well as for me.
We certainly try and get important issues taken care of right
away and keep a proactive approach to the maintenance of each

Walk into Moss' office, and you're greeted with stacks of
documents neatly placed on her desk, along with Gators fanfare
displayed on her walls. She claims not to be very organized,
but we don't buy that her performance speaks volumes of
her superb ability to keep the multitude of projects in order.

"I'm really picky about details," Moss said. "1 re-check the
proposals a lot. 1 just do my best to try and get what needs to
be done in a very professional and organized way, even though
if you look at my desk, it is not very organized. It is somewhat
organized in my mind."

For the past three years, Moss has worked with the CMS, and
has done a great job of keeping the center's fiscal matters on



track. During the center's request for proposal period, Moss
works with civil and coastal engineering faculty during the
proposal submission phase, specifically reading through
the RFP, making sure the guidelines are being followed
and assisting with budgetary matters. The goal is to ensure
a smooth submission there's a lot of processing to be
done, once all the information is received from the faculty,
she said.

"When 1 talk to the faculty about preparing a proposal, 1
try to stress the importance of starting early and getting all
the information together on time," Moss said. "1 feel my job
is to assist the faculty with as much of the administrative
issues as 1 can, but to also make them aware of any concerns
regarding their research along the way. Between all of us
working on the projects, my goal is to be problem-free."

And problem-free she does keep them, which gives her time
enough for her passion: Gators football and family time.
You know it's game week when she is decked out in orange
and blue come Friday. This is a personal tradition she has
honored for years. Moss never tries to miss a game and
would one day like to meet the team's famed quarterback,
Tim Tebow.

"All 1 have to say is 'Go Gators!'" Moss said. "My family
and 1 love the Gators. 1 grew up watching the games with
my parents, and '11 always be a Gator. The Gator Nation is
an awesome place to be."

Twenty years in the Gator Nation, and she is still going
strong. Thank you, Dona, for continuously providing the
CMS and the Department of Civil Ft Coastal Engineering
with excellent service.

Submitted by: Rod Warner, The City Alliance of Sarasota,
Subject: Roundabouts and Economic Development
Date: 8-24-2009
Question: What evidence do you have of economic
development outcomes following and adjacent to the
installation of modern roundabouts, particularly multi-
lane roundabouts?
Response: (Provided by Dan Burden, Principal and Senior
Urban Designer, Glatting Jackson Kercher Anglin with
supporting commentary by lan Lockwood, Principal and
Senior Transportation Engineer, Glatting Jackson Kercher

Dan Burden:
There is strong and compelling evidence that well-placed
roundabouts do much more to spur on economic and
social exchange at levels well beyond a traffic signal's
performance at the same location. The Clearwater
Beach [Fla.] Roundabout compressed seven signalized
intersections into one 2-lane roundabout, which made
it possible for as many as 15,000 additional beach
goers to get to the beach, spurring a new problem a
need to build massive new levels of parking. In a tight
space, roundabouts can deliver more people to a popular

More compelling, in a more average situation, the
replacement of four signalized intersections along a strip
in Golden, Colo., allowed the merchants in each of the
stores to increase their sales during the last recession, the
only place in all of Colorado reported to have increased

More recently, in Hamburg, N.Y., the replacement of all
five signals with roundabouts on their main street, along
with improvements to the main street, has raised their
popularity and status among the 12 villages from low
in the order, to the No. 2 position. Part of this rise in
popularity was how hard everyone worked together to

make their village a better place, but the quieter, more
peaceful, less aggressive, driving behavior has added
to the charm, dignity, status and income stream of this

Finally, the Bird Rock (La Jolla Boulevard), San Diego,
Calif., series of five roundabouts have made a dramatic
change in the income stream, and the number of new
businesses moving into this now popular corridor. All of
the businesses from small coffee shops to large brand
new drug stores are reporting pleasure to extreme
pleasure with the results.

lan Lockwood:
Roundabouts were usually part of an ensemble of changes
to the street that added value to a community. Normally,
the value uplift is a result of the advancement of
"community" functions along and across the street (such
as walkability, safety, better access, on-street parking and
improved aesthetics being the key benefits). That being
said, a singular change from a signalized intersection
to a roundabout normally increases walkability, safety,
access and aesthetics locally. Thus, even on its own, a
roundabout adds value to a community. Furthermore,
if turn lanes were present at the intersection prior to
the conversion, then the roundabout does not need turn
lanes and, consequently, the on-street parking supply
can increase if desired by the community. Lastly, if a
community realizes the benefits of a roundabout, they
usually recognize the benefits of other supportive street
modifications, too.
