Queue Length Calculation Model at Adjacent Signal Intersections

Abstract:

This paper presents an analysis of the influencing mechanism of time space parameters such as link length, signal offset, splits and so on. Based on the maximum queue length at adjacent signal intersections. The calculation model of the maximum queue length based on the traffic wave theory is created, and the model is verified with microscopic traffic simulation experiments. Then, the concept and its calculation method of time space coordination index of adjacent signal intersections are proposed, and the influence of the law of the time space coordination index on the maximum queue length at adjacent signal intersection is analyzed. The results show that the model can calculate quantitatively the maximum queue length for adjacent signal intersections with time space parameters, and it’s significant in traffic design and optimization for adjacent signal intersections.
