DYNASMART-P is one of the two state-of-the-art dynamic network
traffic operational planning tools developed under the Federal
Highway Administration's (FHWA) Dynamic Traffic Assignment
(DTA) research project. DYNASMART-P, developed by researchers
at the University of Maryland, supports transportation network
planning and traffic operations
decisions, including evaluation
of ITS deployment options,
Ma through the use of simulation-
based dynamic traffic assignment.
E ". This tool combines (1) dynamic
network assignment models, used
primarily in conjunction with
demand forecasting procedures
for planning applications, and (2)
traffic simulation models, used
,' primarily for traffic operational
S-" :L studies. DYNASMART-P
provides the capability to model
L n the evolution of traffic flows in a
traffic network, which result from

.. seeking for the best paths en-route
.... -- over a given planning horizon. It
overcomes many of the known
Limitations of static tools used in
current planning practice. These
Limitations pertain to the types of
alternative measures that may be
represented and evaluated, and
the policy questions that planning agencies are increasingly asked to
DYNASMART-P defines a new generation of transportation
planning methodologies, which can interface readily with existing
four step procedures, yet provides a meaningful jump in the range
and type of measures that can be evaluated. Because it considers the

time-varying nature of traffic
flows, it is expected to produce
more useful estimates of state
variables such as speeds, queue
lengths, delays, and congestion
effects to better assess the
functional and environmental
impacts of a variety of traditional
and emerging transportation
planning measures, including the
deployment of ITS and non-ITS
DYNASMART-P requires
input data commonly used
by the traditional traffic
assignment and simulation
models, particularly with regard
to network representation and
spatial demand loading patterns.
The input data vary with the
network being analyzed and the
level of detail required by the
user. Complexity of the network
could range from a linear
freeway network to an integrated
network with High-Occupancy
Vehicle (HOV) lanes, High-
Occupancy Toll (HOT) lanes,
ramp metering, transit services,
possibly incidents and signal
controlled intersections on
surface streets. Applications to
date have included metropolitan

and regional networks with up
to 35,000 nodes and 100,000
links, with nearly one million
vehicles simulated over horizons
of several hours.
DYNASMART-P produces a
wide array of output information
to assist users in performing
detailed traffic analysis. The
output report contains Measures
of Effectiveness (MoEs)
commonly used by traffic
engineers, such as volumes,
speeds, travel times, delays,
etc. DYNASMART-P also
produces an individual vehicle
trajectory file, which is very
useful for research purposes. In
addition, through its intuitive
graphical user interface (GUI),
DYNASMART-P provides the
user with the means to view
simulation results and other
characteristics through various
graphical formats, both static and
With rich built-in features,
DYNASMART-P can be used to
evaluate complex strategic and
operational network planning
decisions and to produce policy-
relevant traffic assignment results
for planning analyses. The

potential applications include:
Assessing impacts of ITS
and non-ITS technologies
on the transportation
network, such as dynamic
message signs, ATIS under
different information supply
strategies and behavioral
response scenarios, dynamic
route guidance, incident
management, etc.
Supporting decision-making
for work zone planning and
traffic management.
Evaluation of HOV lanes
and HOT lanes.
Evaluation of different
congestion pricing schemes.
Planning for special events
and emergency situations,
including some evacuation
scenarios for homeland
security applications.
Traffic assignment analyses
in traditional planning
functions, as well as in
conjunction with activity-
based and tour-based
DYNASMART-P operates on
Windows XP, Windows 2000,
Windows ME or Windows NT
4.0 (service pack 5) or higher.

A minimum of 300 MB of
the hard drive space and the
minimum of 512 MB of RAM
memory are needed to run the
model, depending the size of
the network and analysis time
period. Execution times vary
with the hardware used and
size of network, though typical
experience on high end PC's
suggests approximately a ratio of
simulation to actual time of 1 to
0.25 0.35 on actual networks.
The FHWA has also
developed a DYNASMART-
P input editor, DSPEd, to
assist users in preparing input
data. Both DYNASMART-
P and DSPEd will soon be
available at McTrans. Please
keep your eye on the McTrans
website. For more information
about DYNASMART-P, please
check the websites: www.
dynasmart.com or www.
Two free training workshops will
be offered by FHWA and the
University of Maryland in the
Washington metropolitan area in
fall 2004. Please contact Henry

Optimization: Preview

Release 10.2 of TRANSYT-
7F will introduce "direct"
CORSIM optimization of
cycle length, splits, and
offsets, using the genetic
algorithm. This version is
targeted for January 2005.
During the beta test period
this Fall, send yourTRF file
to McTrans. If your file is
chosen, we will optimize it
free of charge. Regarding
macroscopic, TRANSYT-
based optimization, release
10.2 will introduce graphical
coding of lane configuration,
peak hour factor, and
saturation flow rate.

For Signalized Intersection
and Urban Street analyses,
the Upstream Filtering or
Metering Adjustment Factor
(I-Value) is a coefficient in the
delay equation to account for
way that upstream signals
decrease the variance in the
number of arrivals per cycle
at the subject intersection,
reducing delay. Many users
leave the default of 1.0,
which is intended only for
isolated intersections at least
one mile from an upstream
signal. The I-Value is based
on the volume-weighted v/c

ratio average of all upstream
movements contributing to
the subject intersection lane
group. This computation will
be automated in HCS+.

U-turns and left-turns can
only be simulated from a
shared lane when actuated
control is used. To model
shared u-turns and left-turns
at a pre-timed controller, it
may be preferable to code
the signal as actuated, but
specify equal maximum and
minimum green times to
emulate pre-timed operation.


After recording hundreds of
test cases, no input file has
ever been found for which
hill-climb optimization
produces a better timing
plan than genetic algorithm
optimization. If you
encounter a TRANSYT input
file for which hill-climb
optimization appears to
produce a better result,
submit it to McTrans. We will
attempt to return it genetic-
optimized with the best
