- INTEGRATED CORRIDOR MANAGEMENT PROGRAM – ANALYSIS, MODELING AND
SIMULATION (AMS) FOR THE I-270 CORRIDOR IN MONTGOMERY COUNTY, MARYLAND
(PHASE I)
Caliper Corporation developed a pilot TransModeler
micro-simulation model for the I-270 corridor in Montgomery County, MD.
This work was conducted for the University of Maryland’s Center for
Advanced Transportation Technology (CATT) and Maryland’s State Highway
Administration (SHA). The objective of this project was to demonstrate
the feasibility and benefits of TransModeler in supporting large-scale
corridor analyses such as the Integrated Corridor Management (ICM)
initiative by the US DOT. The ICM initiative aims to demonstrate the use
of Intelligent Transportation Systems (ITS) to plan and manage congested
traffic corridors by assisting decision-makers in identifying gaps,
evaluating strategies, and investing in the best combination of
strategies that would minimize congestion and improve safety. The I-270
corridor in Maryland is one of eight test sites selected by the US DOT.
- Micro-simulation of Greater Eureka Area, CA
Caliper is presently
developing a micro-simulation model of the Greater Eureka Area (GEA) in
Northern California for the California Department of Transportation
(Caltrans) and Humboldt County. The simulation in TransModeler will be
integrated with the GEA travel model in TransCAD and will include a
number of base year and future scenarios. Ultimately, the simulation
model and the GEA travel model will together provide a comprehensive
travel demand and traffic simulation platform with which Caltrans,
county, and city staff can evaluate projects now and in the future.
- County Route 93 (Myers Corners Road/Middlebush Road) Corridor Management
Plan
The Poughkeepsie-Dutchess County Transportation Council (PDCTC) is
working with Wilbur Smith Associates to develop a Corridor Management
Plan that identifies and recommends policy and project actions to
improve vehicular and non-vehicular movement along CR 93 in the Town of
Wappinger, New York. The Town of Wappinger sits in the southern part of
Dutchess County, which has experienced a large increase in population
over the past ten years. This increase in population has contributed to
increased traffic volumes on the CR 93 corridor and, in turn, resulted
in poor levels of service during peak periods. Dutchess County and the
Town of Wappinger expect future population growth and the continued
appeal of CR 93 to intensify already poor traffic conditions. The CR 93
Corridor Management Plan will inform decision-makers, the public, local
agencies, and other stakeholders about the causes of traffic congestion
on CR 93 and recommend potential solutions. As part of the analysis,
Wilbur Smith Associates will use TransModeler to prepare
micro-simulations of the corridor, including current year and future
year base scenarios as well as several future year alternatives
implementing various land use and transportation strategies. The
TransModeler micro-simulations will allow the PDCTC, the project’s
Advisory Committee and the public to visualize alternatives for the
corridor and understand trade-offs between the alternative scenarios.
- State Route 91 corridor system management plan
CLR Analytics is
developing, calibrating, and validating a traffic microsimulation model
for the State Route 91 (SR-91) Corridor System Management Plan (CSMP)
study in Orange County, CA. The calibrated model will be used as the
base model for testing alternative build scenarios under future
conditions. The Orange County section of the SR-91 is 25 miles long
from the Los Angeles County line to the Riverside County line and
includes interchanges with 5 different freeways. SR-91 contains both
HOV, Toll, and mixed use lane facilities. All freeway facilities as
well as most major arterials and their signalized intersections are
included in the model. This model focuses on both the morning and
afternoon rush hours from 6:00 to 10:00 AM and 2:00 to 8:00 PM,
respectively, in order to cover all periods of congested travel.
- Downtown Owensboro traffic study
ENTRAN, PLC is evaluating the impacts
of the Downtown Owensboro Master Plan, a comprehensive set of
recommendations that will change and revitalize the face of downtown in
this western Kentucky city. The recommendation to convert downtown
streets from one-way flow to two-way operation is a keystone of the
entire plan. The simulation model in TransModeler will be integrated
with the TransCAD county-wide travel demand model to predict changes in
travel patterns that would result from the conversion and to evaluate
the associated operational impacts. From the analyses, improvements to
the street system, including the addition of turn lanes and
modifications to traffic signals, will be identified. The study also
will involve a complete street analysis using methods from the recently
completed National Cooperative Highway Research Program (NCHRP) Report
616, Multimodal Level of Service Analysis for Urban Streets. The methods
predict level of service from the perspective of the traveler for the
four modes most commonly found on urban streets – autos, buses, bicycles
and pedestrians. Finally, the project includes a parking inventory and
analysis that will be used to develop a downtown parking management
plan.
