Method, device and system for converting stage structure and ring structure signal schemes

Abstract

The invention provides a method, a device and a system for converting stage structure and ring structure signal schemes and relates to the technical field of traffic signals. The stage structure and ring structure signal scheme conversion method comprises the following steps of obtaining a stage structure; converting the stage structure into an intermediate structure; converting the intermediate structure into a ring structure; wherein the control scheme based on the stage structure comprises specific information of each stage; wherein the control scheme based on the intermediate structure comprises the starting time and the duration time of each phase in the period; wherein the control scheme based on the ring structure comprises the phase number contained in each ring and the sequence of the phase number. According to the method, the stage structure is converted into the intermediate structure and then converted into the ring structure, a mixed integer linear programming model modeling solution method is introduced when the intermediate structure is converted into the ring structure, smooth conversion from the stage structure to the ring structure signal scheme is achieved, and construction of a unified signal control platform is facilitated.

Description

technical field [0001] The invention relates to the technical field of traffic signals, in particular to a method, device and system for converting signal schemes of phase structure and ring structure. Background technique [0002] At present, there are two signal control methods, one is the control method of the US NTCIP (National Transportation Communications for ITS (Intelligent Traffic System, Intelligent Traffic System) Protocol, National Transportation ITS Communication Protocol) based on the ring-boundary implementation, the common control method The form is single-loop or double-loop, and another control mode is the control mode according to the phase phase protocol. [0003] Due to the different architectures of these two protocols, it is impossible to achieve smooth mutual transfer. Since the configurations of different intersections are not the same, many omissions and mismatches will inevitably occur in the process of mutual conversion, which has caused great har...

[0003] Due to the different architectures of these two protocols, it is impossible to achieve smooth mutual transfer. Since the configurations of different intersections are not the same, many omissions and mismatches will inevitably occur in the process of mutual conversion, which has caused great harm to the access of different signal machines to the unified platform. resistance
