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
