Signal Coordination Modelling for Two Contiguous Intersections Based on the Queue Length
摘要
Intersection can be defined as where two or more roads join or intersect, including roads and roadside facilities for traffic movement within them. This research was conducted at two level intersections, which have a distance between the intersections of 158 m. Coordination of signalized intersections aims to reduce the occurrence of queues and delays at several adjacent signalized intersections. The research method used a microscopic model to see intersection performance optimization and intersection coordination analysis. Based on the survey results during rush hour, From the initial analysis of existing intersections, the average degree of saturation (DS) and queue length for each intersection exceeds the recommended limit. Alternative to optimize the performance of the intersection is selected based on the results of the simulation analysis. Alternative 1 (intergreen 6 s) obtained in the degree of saturation and queue length with an average decrease for the degree of saturation is -14.93% and for the length of the queue is 27.71%. Alternative 2 (intergreen 4 s) obtained in the degree of saturation and queue length with an average decrease for the degree of saturation is -19.13% and for the length of the queue is 31.72% of the existing conditions.
