Optimization of Pedestrian-Only Phase for Signalized Intersection

抄録

To provide pedestrian friendly environment is one of the most important policy of transportation system development in Taiwan. Therefore, in Taiwan, the pedestrian-only phase has been implemented at many intersections to support a policy of human-oriented transportation development for providing a better environment for pedestrians. This paper aim to develop an optimized, group-based signal timing model for the pedestrian-only phase of intersections based on a traffic flow stream-conflict matrix. The relationships among starting time point of green time and the length of effective green time, and lost time were the variables considered for generating a model for optimal signal timing. By conducting a field survey using real cases, the model was developed and applied. The results of optimization of signal timing show to be able to improve the efficiency of intersection signaling compared to existing signal timing.
