2010 Highway Capacity SoftwareTM

Under Development ...


Work on HCS'" to implement the updated procedures
coming in the 2010 HCM has made great progress.
McTrans' goal is to be ready with the HCS upgrade to
coincide with 2010 HCM publication.


The major overhaul to a
comprehensive module to
implement the new pro-
cedures for signalized
intersections, urban
streets and interchange
ramp terminals, built
from an entirely new pro-
gram architecture to take
advantage of the latest
programming techniques,
is certainly the biggest
challenge.


A "ME

This new structure will IFill2UKWA S V -
not only make imple-
menting these complex
new procedures much
more efficient, it will also provide maximum flexibility
to the user with many alternatives built into the interface.
Our goal is to blend the familiar screens with new op-
tions to make the transition for users easier, while adding
functionality.


As you will see on the next two pages, there has been a
lot of effort devoted to providing the best of what HCS
has been while adding many now features to improve
functionality and efficiency for the user.

STREETS








HCS 2010


Streets, Signals and Interchanges


Urban Streets (HCM Chapters 16 and 17)
Signalized Intersections (HCM Chapter 18)
Interchange Ramp Terminals (HCM Chapter 22)

McTrans has focused on the major upgrade to the
Streets, Signals and Interchanges modules that imple-
ment the new HCM procedures for HCM Chapters 16,
17, 18 and 22. Signals and Interchanges are subsets to
Streets in this new integrated design.

There are now two options for data entry for these com-
bined modules. The traditional split screen with dy-
namic reports (classic mode) and a graphical option with
tabular screens (visual mode).

Classic Mode

The more familiar split screen has been organized to
permit the most common data entry on one view without
having to scroll, while providing for detailed data op-
tions below and the dynamic report in the lower pane.


Visual Mode

This new screen facilitates locating intersections (both
signalized and access points) for the urban street geo-
graphically. It also provides a set of tabs to access data
for each intersection as it is selected from this view.
Each tab presents a different section of the input data


[.. -... .


organized into general, intersection, traf-
fic, phasing, timing, segment, access
points and other detailed data. A context
menu is provided to supplement tool bar
access. Delay and LOS results are dis-
played by approach for any selected inter-
section.

More New Features ...

* One-touch animation for multiple
signals in a street analysis

* One-touch optimization using TRAN-
SYT-7F on an arterial


Quick Entry, Quick Lanes and Quick Phases

To expand features for more efficient and more intuitive
data coding, McTrans has added a more comprehensive
preliminary screen (Quick Entry) to establish a set of
data values to begin an analysis. Users can even design
their own set of customized initial values and settings.

A new graphical tool (Quick Phases) provides for enter-
ing NEMA Phasing data with a companion Sequential
Phasing graphic to help in this transition. The lane con-
figuration tool (Quick Lanes) has been retained as it
functioned in HCS2000 and HCS+.


* Replication of intersection data to facilitate coding
multiple similar signals along an urban street facility

* Multiple-period analysis for analyzing congested
conditions for signals, interchanges and streets

* SpyGlass to view details of the procedure not docu-
mented directly in the HCM, only in engine code

* Customizable modular templates for reusable data

* Customizable and redesigned formatted reports

* Time-space diagram to visualize signal coordination

HCS 2010


Major Overhauls


Roundabouts (HCM Chapter 21)

This HCS module has been upgraded to include the abil-
ity to analyze one-lane or two-lane roundabouts for re-
sults that include delay and level of service based on US
conditions. Multilane entries and exits, as well as right-


turn yielding or non-yielding bypass lanes,
commodated. The procedure can deal with

Significant Changes


Off-Street Pedestrian and Bicycle Facilities
(HCM Chapter 23)

This brand new module within HCS will provide for one
program to analyze pedestrians and bicycle on off-street
facilities, including the results of FHWA research. the
results include capacity and level of service for walk-
ways, stairways, exclusive off-street bicycle paths and
shared-use paths.


Two-Lane Highways (HCM Chapter 15)

A third class of two-lane highways is introduced for
roadways that serve moderately developed areas passing
through small towns or developed areas. The analysis of
bicycles along the two-lane roadway is also included.
The two-way analysis is eliminated in favor of a
weighted average of directional results.

Basic Freeway Segments (HCM Chapter 11)

New speed-flow curves are implemented with the modi-
fied module, with no interpolation between free-flow
speeds. The adjustments to base free-flow speed have
also been changed to include ramp density and eliminate
the adjustment for number of lanes. A permanent curve
for 75 mi/h free-flow speeds has been installed.


Freeway Weaving Segments (HCM Chapter 12)

Lane-changing rates as direct measures of turbulence are
now key to this analysis. Weaving and non-weaving
speeds are computed for various lane configuration, in-
cluding one-sided and two-sided weaving, with maxi-
mum weaving lengths determined. Capacities are pro-
duced for ideal and prevailing conditions. Level of ser-
vice is based on den-
sity, except for v/c
ratios over 1 0


More Changes


Multilane Highways (HCM Chapter 14)

The analysis of bicycles is now included, along with the
elimination of free-flow speed-interpolation.


Two-Way Stop Controlled Intersections
(HCM Chapter 19)

The ability to analyze intersections with a six-lane major
roadway, including U-tums, is now implemented.

All-Way Stop Controlled Intersections
(HCM Chapter 20)


The ability to analyze AWSC intersections with three-
lane approaches is now implemented.


Freeway Facilities (HCM Chapter 10)

The update will implement the new weaving methodol-
ogy and provide for a facility LOS based on density.

Freeway Merge and Diverge Segments
(HCM Chapter 13)

Minor changes provide for lane balancing of flow rates
and to eliminate a discontinuous density situation.
