| Summary | The Ministry of Transportation and Communications (MOTC) has put an emphasis on implementing ITS now and in the future. After several years of deployment experiences, Institute of Transportation (IOT) developed the pre-timed, traffic-actuated and traffic-responsive signal control logic in 2001. The logic has been used to developing the new traffic signal software by MOTC. Since then it has been widely used in Taiwan. Therefore, this study develops a network adaptive signal control model l based on the adaptive arterial signal control model developed in the last year. Field tests and operation evaluations were conducted in this study. The result of this study can serve as guidance on the development of adaptive traffic signal control. The major contributions of this study are: Development of the adaptive traffic signal control model- Network Coordinated Traffic adaptive Signals system. Comparative analysis of the pre-timed and the adaptive traffic signal controls by simulation. The hardware architecture plan of network intersections adaptive signal control model. The software developing plan of network intersections adaptive signal control model. Analysis of traffic characters and operation evaluations that may meet in the field test. The benefit and cost analysis for developing the adaptive traffic signal control model. Submitting an initial proposal for future development. After field tests, we found that the network adaptive signal control model is more effective. It not only can reduce the stop delay in effect for per vehicle but also has highly economical benefit in cost-benefit analysis. |
