Embodiment Construction

[0030] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0031] A kind of abnormal vehicle behavior detection and tracking device based on DSRC of the present invention, such as figure 1 As shown, including vehicle-mounted terminal, roadside dedicated short-range communication unit, road-based computer unit and management center computer;

[0032] The vehicle-mounted terminal is recorded as OBU, and the vehicle-mounted terminal is installed on the motor vehicle;

[0033] The roadside dedicated short-range communication unit is recorded as RSU, which is set on the roadside of the detected area. The roadside dedicated short-range communication unit includes an antenna array and a multi-input multi-output transceiver hardware platform. The antenna array communicates with the multi-input multi-output information through the feeder Hardware platform connection, multi-input multi-output information sending and r...

Abstract

The present invention discloses a vehicle abnormal behavior detection and tracking method based on DSRC. The method comprises: a road side personal communication unit is configured to obtain information from a vehicle device, a roadbed computer is configured to calculate the information to obtain the speed of the vehicle, the traffic flow of the road and the traffic density, perform speed abnormity determination through adoption of a threshold value comparison method by a abnormity detection module and determine the vehicle illegal parking and retrograde motion through a design algorithm. Through adoption of a DSRC communication technology between vehicles and roads, the vehicle abnormal behavior detection and tracking method based on DSRC provides a calculation method of microcosmic traffic volume, vehicle speed, macroscopic traffic volume, traffic flow and traffic density so as to solve the problem that the vehicle abnormal behavior is identified and tracked with low cost and accuracy in the car networking environment.

Description

technical field [0001] The invention relates to vehicle networking technology and DSRC communication technology, in particular to a DSRC-based abnormal vehicle behavior detection and tracking method, which belongs to the field of computer technology. Background technique [0002] In 2013, the number of motor vehicles was 137 million. By the end of 2014, the number of motor vehicles was 264 million. By the end of 2015, the number of motor vehicles was 279 million. With the increase of vehicle ownership, illegal and criminal accidents related to vehicles emerge in an endless stream. In 2012, there were 190,756 motor vehicle accidents, with 57,277 deaths and 210,554 injuries. In 2013, there were 183,404 motor vehicle accidents, 55,316 people were killed in motor vehicle traffic accidents, and 198,317 people were injured in motor vehicle traffic accidents. In 2014, there were 18,321 motor vehicle traffic accidents, with 54,944 deaths and 194,887 injuries. In order to reduce t...
