Method and system for traffic information acquisition and event processing

Abstract

The invention discloses a method and a system for traffic information acquisition and event processing to acquire traffic information of a plurality of road sections in real time so as to achieve the management of the plurality of the road sections according to the traffic information. The method comprises the following steps: selecting an information acquisition cycle; acquiring traffic data of certain road section in real time at the end of each information acquisition cycle, wherein the traffic data comprises traffic occupation ratio and speed; preprocessing the traffic data; and performing traffic state analysis and traffic event detection analysis on the traffic data to obtain traffic state information and traffic event information of a corresponding road section. The method and the system achieve automatic discrimination and timely issuance of road traffic states and traffic events on the basis of the acquired traffic data and save a great deal of workload for manual judgement; and simultaneously, the information issuance is simple, intuitive and timely, and can provide real-time traffic road condition information for traffic controllers to lead the traffic in time, and guide a driver to select a best traveling route.

Description

technical field [0001] The invention relates to a traffic management method and system, in particular to a traffic information collection and event processing method and system. Background technique [0002] With the rapid development of urban economy and the sharp increase of car ownership, the main nodes and sections of urban road traffic will be saturated during morning and evening peak hours. How to collect accurate traffic data to provide support for traffic decision analysis, through specific analysis of traffic data, to determine the traffic status of each road section, to induce drivers to choose an appropriate path, and to achieve a reasonable distribution of traffic flow; When a traffic incident is detected, the staff will confirm the cause of the incident and quickly deal with various emergency traffic incidents, which is an urgent problem that needs to be solved at present. [0003] However, the collection of urban road traffic information is mainly aimed at urb...

Problems solved by technology

[0003] However, at present, the collection of urban road traffic information is mainly aimed at urban expressways or expressways, and the construction of urban surface roads with a denser road network has just begun to be tried, and the traffic mechanism of intermittent flow and continuous flow of urban roads is not much. The same, its traffic status judgment and traffic incident detection need to be reconsidered
