Method for monitoring control state of bottleneck

Abstract

The invention relates to a method for monitoring the control state of the bottleneck. The method comprises steps of: obtaining data of all of the intersections in the bottleneck control sub-area and adjacent intersections; selecting an intersection as a central intersection, and then displaying an interface, which comprises the intersection and other five intersections in the east, west, south andnorth, in a graphical form, wherein each intersection contains four directions of east, west, south, and north; displaying the phase lamp state in real-time, a phase flow, the release time of the phase in one cycle, the change amount of the release time of the phase in the cycle and the upper cycle, the occupancy rate of the road segment detector, and the occupancy rate of the overflow detector on the graphical intersection; controlling the phase release of the upstream and downstream intersections by modifying thresholds, according to the values of the occupancy rate of the road segment detector and the occupancy rate of the overflow detector. According to the method for monitoring the control state of the bottleneck, the method is easy to realize, is high in efficiency, is rich in display data, is capable of controlling the release state of the intersections, integrates the display and the control, and can be integrated into an actual road traffic control system.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control systems, and in particular relates to a method for monitoring a bottleneck control state. Background technique [0002] Since the 1950s, with the rapid progress of computer technology, the intelligent transportation system (ITS) has entered the process of rapid development. The field of ITS has become more and more extensive, and it has gradually become an important way to improve the level of urban traffic management. . [0003] The problem of traffic congestion in big cities is becoming more and more serious, which seriously affects the development of social economy and people's quality of life. In intelligent traffic control, bottleneck control is a very important control method and plays an important role in solving traffic congestion. The ensuing requirement is that the center can monitor the control status of the bottleneck control sub-area, verify the effectiveness of the bottlen...

Problems solved by technology

[0004] At present, most of the existing domestic intelligent traffic signal control systems lack a tool that can simply, intuitively, and graphically reflect the bottleneck control status, and the bottleneck control needs to monitor the distance between adjacent intersections due to special control methods such as current limiting and entry prohibition. The relationship between only showing the state of one intersection cannot meet the requirements, and cannot fully express the control idea of ​​bottleneck control
