Embodiment Construction

[0015] In the present invention, the operation mode of the traffic signal control system is still divided into three operation modes: regional coordination control, line coordination control and single-point control, and the single-point control operation mode is divided into single-point optimization control, single-point induction control, and single-point control. There are four operating modes: multi-period timing control and single-point yellow flash control, all of which are macro-operating modes. However, at the micro level, the regional coordination control operation mode is divided into three operation modes: regional coordination heavy traffic control, regional coordination traffic control and regional coordination light traffic control operation mode; line coordination control operation mode is divided into line coordination heavy traffic control, line coordination medium traffic control mode There are three operation modes of traffic control and line coordination, a...

Abstract

According to design scheme provided by the invention, the disclosed method includes three operation modes in macroscopy: regional coordinated control, line cooperative control, and single point control. Characters are that real time traffic demand is divided into three states: light traffic, medium traffic and heavy traffic. It is light traffic if traffic flow is lower than a setting value V1. It is heavy traffic if traffic flow is higher than a setting value V2. It is medium traffic if traffic flow is higher than V1 and lower than V2. Based on timetable built in, operation modes in macroscopy are switched at set time. Based on traffic state in real time, microscopic operation modes are self-adaptive switched automatically.

Description

technical field [0001] The patent of the present invention relates to the working principle and method of self-adaptive conversion of the operation mode of the traffic signal control system applied to the regional road network. It is suitable for traffic signal control of urban road network. Background technique [0002] The traffic signal control system is used to control the traffic signals of the urban road network. At present, its working mode includes three operating modes: regional coordinated control, line coordinated control and single-point control. The single-point control operation mode also includes single-point induction control , single-point multi-period timing control and single-point yellow flash control three operating modes, see figure 1 . my country's public safety industry standard GA509-2004 defines the above-mentioned mode, and the specific description is as follows: 1. Regional coordinated control: a control method that coordinates and controls traf...
