Appl. No.:
9/108833

Abstract:
An interface device between a computer running a traffic simulation program and any number of traffic signal controllers. The traffic simulation program simulates traffic in a road network including signal-controlled intersections. There are many signal manufacturers and they do not release the details of the control algorithms used in their controllers, hence it is impractical if not impossible to merely insert the control algorithm for a given controller into the program. The interface of the present invention allows any controller from any manufacturer to be used with the simulation program so that traffic flow in any network including signal-controlled intersections can be simulated. An assumed traffic network and demand traffic is input into the program; the program sends detector actuations to the signal controllers via the interface device and the controllers's phase indication states are sent back into the program also via the controller. The program then integrates this feedback into its operation and simulates the way traffic will flow through the road network having intersections with these particular signal controllers.
