Bottleneck Analysis of Ground Bus Intersection Operation

The unobstructed situation of urban passenger transit corridors directly affects the efficiency of urban traffic operations. This paper analyzes the characteristics of bus operation, defines the bottleneck of the bus intersection and analyzes various factors related to it. Based on the bus big data, the identification index, and calculation method of the bottleneck of the bus intersection are proposed, and the bottleneck identification system is constructed. Finally, taking the passenger transit corridor of Guanhe Road in Changzhou City, Jiangsu Province as an example, the time, space, and severity of the bus bottleneck running on the Guanhe Road Corridor were identified, and the typical causes were analyzed. It is of great practical significance to promote the construction of the bottleneck identification system for bus intersections based on public transport big data, which will help to improve the operational efficiency of the ground crossings in passenger transit corridors.
