Abstract

The invention relates to an area traffic jamming triggering point record analysis system and an operation method thereof; the system is composed of an analysis processing computer arranged at the control center, a traffic jamming rapid alarming device arranged on the detection point of the road and a communication line; a jamming detection point upstream and downstream relation database is preset on the analysis processing computer, and a triggering point analytical procedure is operated; after the analysis processing computer receives one jamming alarming message transmitted by the jamming rapid alarming device at each time, the triggering point analytical procedure is started immediately; after the triggering point analytical procedure finds that traffic jamming happens at one jamming detection point, the downstream jamming detection point of the jamming detection point is searched from the upstream and downstream relation database, and according to the current jamming state and the occurrence time of the current jamming state of the downstream jamming detection point, weather the jamming is affected and generated by the downstream traffic jamming waves is deduced, if yes, the head of a jamming chain is found as the triggering point and a prompt message is given, and the prompt message can be stored separately for use in the future.

Description

technical field [0001] The invention relates to a system for quickly recording and analyzing traffic congestion trigger points within an area in urban traffic management and an operating method thereof. Background technique [0002] With the rapid development of cities, the road traffic flow in large and medium-sized cities is close to saturation during peak hours. Due to problems in road planning, road design, and traffic management at a certain point, it often leads to large-scale congestion of traffic in a region during peak hours, thus greatly reducing road capacity and bringing extreme travel problems to people. Big inconvenience. [0003] It is the key to improve the traffic capacity of urban roads to accurately find out the trigger points that cause large-scale traffic congestion and take corresponding measures to solve them. [0004] In the current urban road traffic management, there are detection and alarm devices for road traffic congestion. Such devices can det...
