Embodiment Construction

[0010] The present invention comprises the following steps:

[0011] 1) Record the driving track of the vehicle in real time by a driving recorder with GPS, and transmit the driving track signal to the control center of the remote traffic police management department through a wireless signal transmitter, and the wireless signal transmitter controls the start of the vehicle through the signal provided by the speed sensor. Closed, the vehicle speed sensor is used to detect the rotational speed of the wheel, when the vehicle speed sensor detects that the rotational speed of the wheel is not zero, the wireless signal transmitter works, and the transmission frequency of the wireless signal transmitter is 0.1s / time;

[0012] 2) The control center stores the collected driving trajectories of each vehicle in the database, and the control center stores the collected driving trajectories of each vehicle in the database, and each vehicle in the database only records the driving trajector...

Abstract

The invention discloses a method for analyzing traffic accidents. The method includes the steps that an automobile data recorder with a GPS is used for recording driving tracks of vehicles in real time; driving track signals are transmitted to a remote traffic police administrative department control center through a wireless signal transmitter; the control center imports the collected driving track data of all the vehicles into an electronic map in real time, and a driving track group is formed on the map; whether accidents happen or not is judged according to the driving track group, and the confirmation of responsibility of the accidents is also judged. By the adoption of the method, efficient, low-cost and high accuracy analysis can be made according to specific traffic accidents.

Description

technical field [0001] The invention relates to an analysis method, in particular to a traffic accident analysis method. Background technique [0002] At present, there are many traffic accident information collection systems in China. All provinces, cities and the Ministry of Public Security have launched relevant traffic accident information systems, but they only stay at the stage of data entry. All kinds of traffic accident databases can only perform simple data statistics and queries. And other functions, the analysis of traffic accidents only starts from the data, and analyzes the accident frequency of each road section, so as to infer which road sections need strict traffic control, and which road sections can relax manpower and material resources. [0003] However, the above-mentioned analysis is mainly aimed at the problem of unified urban traffic planning, and provides solutions. The analysis for specific traffic accidents is basically carried out through manual id...
