| Summary | Since the Ministry of Transportation and Communications (MOTC) emphasized her efforts on the ITS development, Institute of Transportation (IOT) has finished a series of researches on the pre-timed, traffic-actuated and traffic-responsive signal control logics. IOT has integrated these achievements with the 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 last-year (2004) research about the adaptive signal control model used for isolated intersection.. 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: Develop the adaptive traffic signal control model-Arterial Coordinated Traffic-adaptive Signals system (ACTS) that includes time-step model (ACTS-T) and cyclic model (ACTS-C). Evaluate the differences between pre-timed and adaptive traffic signal control by simulation experiments. The hardware architecture plan and the software developing plan of arterial intersection adaptive signal control model. Confer and analyze the topics of traffic characters and operation evaluation that may meet in the field test. The cost and benefit analysis for developing the adaptive traffic signal control model. Provide an initial proposal for future development. After field test, we can certainly understand that the arterial intersections adaptive signal control model results in good traffic performance. It can not only reduce the stop delay in effect for per vehicle but also has highly economical benefit in cost-benefit analysis. |
