Title: Device and method for detecting abnormality in traffic flow
Inventor: HATTORI OSAMU
IPC: G08G1/042
Filed: 2001-06-26
Abstract: PROBLEM TO BE SOLVED: To detect the occurrence of a sudden event on a road such as a traffic accident or landslide in accordance with a time variation in the number of existing vehicles by finding the time variation of the number of vehicles existing on a road in a predetermined section in accordance with the measurement result of a vehicle sensor. SOLUTION: If a traffic flow is in a steady state, the number of vehicles flowing into an area or section is almost equal to the number of vehicles flowing out thereof. Therefore, here is almost no change in the number of vehicles existing in the area or section. However, when a sudden event such as an accident occurs, the traffic flow is disordered and so an unstable change occurs in the number of vehicles existing in the area or section. By calculating the increasing/decreasing number of vehicles existing on the road, the occurrence of the sudden event on the road can be precisely detected.
