TransModeler Traffic Simulation Software

Traffic Control

TransModeler simulates traffic signals and a variety of Intelligent Transportation Systems (ITS) applications.

Traffic Signals:

When you need to understand how traffic signal operations impact the adjacent intersections in the network, simulation is the only option. Simulation is especially important in oversaturated conditions in which queues may spill back to upstream intersections or disrupt the arrival patterns of traffic between intersections, phenomena that are not well accounted for in traditional methods employed by other signal optimization software.

TransModeler simulates a wide range of traffic signal controls:

  • Simulate common traffic signal systems, including pretimed and traffic actuated signal control
  • Simulate more complex traffic signal control systems, including coordinated and coordinated actuated control
  • Model transit signal priority and queue-jumping strategies for bus, rapid transit, or other public transportation services
  • Model signal preemption strategies for transit or emergency vehicle applications
  • Evaluate signal warrants and generate timing plans based on turning movement volume tables
  • Apply customizable templates to create actuated signal controllers, either based on ring & barrier concept or phase group diagrams

ITS Applications:

TransModeler is capable of simulating driver response to a wide variety of traffic control and information devices for Intelligent Transportation Systems applications.

  • Model lane use signs and flexible variable message signs directed at trucks, transit vehicles, and other classes of vehicles
  • Simulate the impact of variable speed limit signs on traffic flow
  • Evaluate the effects of ramp metering on freeway ramp and adjacent urban street operation
  • Simulate the impact of real-time traffic information on dynamic driver rerouting
  • Evaluate dynamic congestion pricing measures and HOT lanes
