Method for passing motor vehicles at multiple intersections with decentralized signal control organization

Abstract

The invention discloses a motor vehicle multipath intersection passing method through disperse signal control and organization. The passing method comprises following steps: S1, successively numbering inlet channels of n paths of signal controlled intersections as 1, 2,..., i,..., n; S2, by use of internal space of the intersections, transforming each inlet of the n paths of signal controlled intersections into a micro-type intersection formed by three inlet channels; S3, using the inlet channel I of the original n paths of signal controlled intersections as one inlet channel of the micro-type intersection, wherein the inlet channel is formed by n-1 paths of lanes and is lead to rest n-1 outlet directions of the n paths of signal controlled intersections; and S4, forming the other two inlet channels of the micro-type intersection by a connection line of an inlet channel i and the adjacent inlet channel i-1 and a parallel line of the connection line as well as a connection line of an inlet channel i and the adjacent inlet channel i+1 and a parallel line of the connection line. According to the invention, average saturation and average vehicle delay of the intersection are reduced; passing ability of the inlet channels is improved; and queuing length is reduced.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a method for passing motor vehicles at multiple intersections with decentralized signal control organization. Background technique [0002] On urban roads, signal-controlled multi-way intersections usually have the following traffic problems: [0003] (1) The more intersecting roads, the more phases are required, the longer the signal cycle, the longer the waiting time of the vehicle when encountering a red light and the more lost time in the cycle; [0004] (2) The internal space of the intersection has not been fully utilized. [0005] As the traffic rules of signal-controlled intersections become more complex with the increase of the number of intersecting roads and the signal phase, the traffic capacity is limited by the signal timing scheme, and signal control delays will occur, and the traffic efficiency of vehicles will inevitably decrease. Therefore, multi-way Traffic a...

[0005] As the traffic rules of signal-controlled intersections become more complex with the increase of the number of intersecting roads and signal phases, the traffic capacity is limited by the signal timing scheme, and signal control delays will occur, and the traffic efficiency of vehicles will inevitably decrease. Therefore, multi-way Traffic at intersections requires a simpler and more efficient way of organizing traffic
