Traffic Control

Traffic Signals:

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
