TransModeler

TransModeler is a based traffic simulation platform for doing wide-area traffic planning, traffic management, and emergency evacuation studies that is developed by Caliper Corporation. It can animate the behavior of multi-modal traffic systems to show the flow of vehicles, the operation of traffic signals, and the overall performance of the transportation network.

TransModeler can simulate many kinds of road networks, including freeways and downtown areas, and can analyze wide-area multimodal networks. It can be used to model and visualize the behavior of traffic systems in a 2-dimensional or 3-dimensional GIS environment to illustrate and evaluate traffic flow dynamics, traffic signal and ITS operations, connected and automated vehicles (CAVs), and overall network performance. Like other Caliper Corporation products, TransModeler is a native GIS environment. TransModeler integrates with TransCAD, the travel demand forecasting software. TransModeler includes a proprietary BASIC-like programming language (Caliper Script) within a development interface (GISDK) that allows automation of the TransModeler environment. TransModeler includes a relational database and a matrix engine for native matrix operations. TransModeler simulates public transportation as well as bicycle, car, and truck traffic. Transit route system travel demand can be specified as either schedule or headway based. Pedestrian crossing demand can also be simulated. TransModeler is inherently a trip-based microscopic simulation package. Demand can also be simulated using turning movement volumes. The trip-based routing handles a wide variety of intelligent transportation system (ITS) features such as managed lanes (such as HOV and HOT lanes), electronic toll collection, route guidance, and traffic detection and surveillance. Simulation-based dynamic traffic assignment (DTA) can be used to inform vehicle's route choices. Calibration methods like Origin-Destination Matrix Estimation (ODME) are also available. TransModeler's road editor natively supports two-way links and roads, which enables automatic handling for two-way left-turn lanes (TWLTL) and automatic handling of overtaking/passing on two-lane highways. Vehicle conflict points and yield points are automatically calculated inside of intersections. Road networks can be imported from Synchro, CORSIM, and TransCAD line layers. TransModeler is integrated with the Highway Capacity Software (HCS) in that it can be used to simulate Urban Streets, Freeway Facilities and Stop-Controlled Intersection (TWSC/ASWC) files created in HCS. TransModeler includes various tools for managing a simulation project and the associated scenarios. Project databases, traffic signal timing plans, and other input data can be shared between multiple projects and scenarios. ==TransModeler Projects== TransModeler is used for projects throughout the world. ==Release history== TransModeler 1.0 - December 2005 TransModeler 2.0 - January 2009 TransModeler 3.0 - December 2012 TransModeler 4.0 - October 2014 TransModeler 5.0 - March 2018 TransModeler 6.0 - October 2020 TransModeler 6.1 - January 2022 ==See also== Maptitude GIS mapping software Caliper Corporation ==References== ==External links== TransModeler official website - Caliper Corporation
