| Summary | Since the Ministry of Transportation and Communications (MOTC) emphasized her efforts on the ITS development, Institute of Transportation (IOT) has finished series of researches on the pre-timed, traffic-actuated and traffic-responsive signal control logics. IOT has integrated these achievements with the development of traffic signal software, developed by MOTC, as a set of standard traffic control system in Taiwan. This research goes a step further to integrate the software and hardware structure based on the conclusion of the previous research about adaptive signal control model. Field tests and operation evaluations were conducted in this study, and the outcomes can be served as a reference for the development of adaptive traffic signal control system. The major achievements in this research include: evaluate the differences between pre-timed and adaptive traffic signal controls by simulation experiments analyze the principles of deploying vehicle detectors by simulation experiments evaluate the strategies of mulit-phase signal control by simulation experiments accomplish the hardware architecture plan of isolated intersection adaptive signal control model accomplish the software developing plan of isolated intersection adaptive signal control model investigate and analyze the topics of traffic characteristics and operation evaluations that may be occurred in the field test and provide an initial proposal for further researches. After the field test, we can assure that good traffic performance was achieved by the isolated intersection adaptive signal control model. It can reduce not only the stop delay effectively for individual vehicle but also has highly economical benefits in cost-benefit analysis. |
