Intelligent Warning Scheme against Secondary Traffic Accident Based on Multi-Source Data

Traffic accidents have been the main concern in traffic safety improvement and the research focus of intelligent transportation. An initial traffic accident may make an area prone to secondary accidents. This paper uses traffic accident data of Guiyang 2015, with reference to secondary accident judgment standard. The time and place of secondary accidents are extracted to build an intelligent warning system for secondary accidents. When a traffic accident occurs, a smartphone is used to upload the vehicle sensing data of the accident location and the driving direction of the vehicles. Based on historical traffic accident data, the warning system determines whether the site is a secondary accident-prone location. Using mobile clients, the system sends accident warning information to phones in the vehicles between the warning area and the accident area to prevent secondary accidents. This intelligent warning system is inexpensive, stable, reliable, and capable of real-time warning.
