Expert-system-based AID (Automated Incident Detection) system of road traffic

Abstract

The invention discloses an expert-system-based AID (Automated Incident Detection) system of road traffic. The system comprises a man-machine interface system, a multi-base cooperative system and an incident verification system. The multi-base cooperative system comprises a traffic information collection unit, a GIS-T (Geographic Information System for Transportation)-based database management unit, an AID algorithm automatic recognition unit, a road traffic state judgment unit and a traffic incident management knowledge base which are connected with the man-machine interface system respectively. The traffic information collection unit, the GIS-T-based database management unit, the AID algorithm automatic recognition unit, the road traffic state judgment unit and the traffic incident management knowledge base are connected with the incident verification system respectively. The invention discloses the expert-system-based AID system of road traffic, which can be used for carrying out information interaction with a driver, fast importing traffic information, further judging and verifying types and duration of incidents, and the like.

Description

technical field [0001] The invention relates to the technical field of automatic detection systems, in particular to a road traffic automatic event detection system based on an expert system. Background technique [0002] With the optimization of road construction and control, especially the operation of the current expressway has greatly shortened the transportation time and improved the transportation efficiency, but at the same time, there have been many problems in the management of the expressway, such as traffic congestion and traffic accidents, etc. The problem is becoming more and more serious. Therefore, how to effectively manage and control the vehicle operation of the expressway, so as to make it more intelligent, informatized and modernized has always been the focus and hot spot of research in the field of traffic engineering at home and abroad. [0003] The current management and control of vehicle operation on highways is limited to traffic nodes that are prone...

Problems solved by technology

[0002] With the optimization of road construction and control, especially the operation of the current expressway has greatly shortened the transportation time and improved the transportation efficiency, but at the same time, there have been many problems in the management of the expressway, such as traffic congestion and traffic accidents, etc. The problem is becoming more and more serious. Therefore, how to effectively manage and control the vehicle operation of the expressway, so as to make it more intelligent, informatized and modernized has always been the focus and hotspot of research in the field of traffic engineering at home and abroad.

[0003] The current management and control of vehicle operation on highways is limited to traffic nodes that are prone to traffic jams and traffic accidents, and cannot effectively use the traffic network to dynamically allocate traffic flow.
