TransModeler

Traffic Simulation, GIS,

TransModeler is the name of a traffic simulation product 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 is a traffic simulation package applicable to a wide array of traffic planning and modeling tasks. 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, 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.
