This work was conducted for the University of Maryland’s Center for Advanced Transportation Technology (CATT) and Maryland’s State Highway Administration (SHA). TransModeler - Integrated Corridor Management Program – Analysis, Modeling and Simulation (AMS) for the I-270 Corridor in Montgomery County, Maryland (Phase I)Ĭaliper Corporation developed a pilot TransModeler micro-simulation model for the I-270 corridor in Montgomery County, MD. The completed large-scale model will be used to assist planning and traffic operations staff with conducting scenario analyses and evaluating traffic management strategies for informed decision-making. The high prevalence of truck traffic and the crossings along the Canada–US border cause further challenges to accurately modeling dynamic trip patterns, route selection behavior and vehicle interactions. Time-varying origin-destination (OD) demand are being estimated to match available field data, and a Dynamic Traffic Assignment (DTA) based on TransModeler’s microscopic traffic simulation will be used to estimate a consistent set of congested travel times. The existing micro-simulation database in TransModeler is being expanded to the scope of the regional travel demand model, with a detailed representation of highway geography and traffic signal control in the region. TransModeler - Whatcom County Area-wide Micro-simulation ModelĬaliper is currently developing a microscopic traffic simulation model of Whatcom County, WA.
