| Research Abstract |
An EVALP based traffic simulation system that can simulate traffic signal control and flow in the central area of Hamamatsu has been implemented on a PC in JAVA. We have researched traffic density data in the area and executed traffic simulation for both actual traffic signal control and EVALP based one based on the researched traffic density data. As the simulation results, we have obtained that EVALP based traffic signal control reduces traffic jam 10% to 20% than that of actual control at each intersection in the objective area, where we take the number of car stops as the traffic jam criterion. Even though they have roads whose traffic signals are coordinately controlled in the area, EVALP based single traffic signal control reduces traffic jam 10% to 15% than that of the coordinated traffic signal control. Moreover, we have constructed an EVALPSN based model for coordinated traffic signal control and implemented its simulator on a PC in JAVA as well as. As the results of the simulation to compare the EVALPSN based coordinated traffic signal control to the actual one, it has been shown that the EVALPSN based one has 10% to 15% higher performance than the actual one.
Additionally, considering to PLC (Programmable Logic Controller) that is used as a controller for traffic signal, it is required for EVALPSN traffic signal control to be implemented on PLC as well as the actual one. Therefore, we have shown that EVALPSN traffic signal control can be translated into PLC ladder program.
