Embodiment

[0057] The section from 2003 to 2015 of Shenhai Highway has a total length of 12 kilometers. It is a continuous long downhill, with large slopes, many bends, and narrow roads, which are prone to traffic accidents. The road traffic jam point location method designed by the present invention is used in the management platform, and the information collection is realized through video monitoring. During the project test, a pair of high-definition night vision pan-tilt cameras were set up for video surveillance on this section of the road (covering A\B) at intervals of about 1,000 meters. The monitoring range is 1000 meters on the left and right, and each high-definition camera corresponds to a video detector for automatic video analysis (the detection area is 300 meters on the left and right).

[0058] In good weather conditions, the monitoring platform only needs to use the blocking area search method in the road traffic jam search and location method to complete the traffic acciden...

Abstract

The invention discloses a highway traffic jam locating and searching method which is implemented on the basis of monitoring systems arranged on the way. The method includes jam area searching and jam point locating and searching. As for a monitoring system which is visual and can fully monitor road situations between two monitoring points, the jam area searching mode is adopted. As for a monitoring system which is visual but can not fully monitor the road situations between the two monitoring points and a non-visual monitoring system, the jam point locating and searching mode is adopted. The jam point locating and searching mode includes the steps that traffic flow data of multiple monitoring points of the upstream of the minimum traffic flow obtained through the monitoring system are fitted into an upstream flow curve; traffic flow data of multiple monitoring points of the downstream of the minimum traffic flow are fitted to form a downstream flow curve; the intersection of the two curves is obtained to serve as a jam point. By means of the method, specific positions of traffic jams and accidents and particularly blind areas between the monitoring points can be accurately located, and adverse effects of rainy and snowy days can be overcome.

Description

Technical field [0001] The invention belongs to the technical field of traffic control, and is particularly related to the early warning processing of traffic accidents, and specifically refers to a method for locating and searching for road traffic jams. Background technique [0002] Traffic jams seriously affect people's normal travel and work efficiency. According to statistics, the cause of traffic jams is generally due to the large traffic volume in the area, especially traffic accidents. A traffic accident refers to an incident in which a highway vehicle causes personal injury or death or property loss due to fault or accident on the road. All over the world, road traffic accidents have become a major public hazard in society. Traffic accidents usually cause road congestion and unsmooth traffic. If the traffic management platform can timely and accurately know the location of the congestion, it can judge that the area may have hidden dangers or have occurred, and can dispa...
