Method for evaluating risk level of road area

The invention provides a method for evaluating the risk of a road area, which comprises the steps of collecting vehicle parameter information by using sensors and OBUs carried by a vehicle, taking a certain area in front of the driving vehicle as a target, and collecting parameter information of all...

Beschreibung
Zusammenfassung:	The invention provides a method for evaluating the risk of a road area, which comprises the steps of collecting vehicle parameter information by using sensors and OBUs carried by a vehicle, taking a certain area in front of the driving vehicle as a target, and collecting parameter information of all vehicles in the target area; and processing the parameter information of the vehicles in the targetarea, calculating the energy association strength of two vehicles and an inter-vehicle relation of the two vehicles, and obtaining group energy of the target area according to a group energy formulaof a vehicle cluster; abstracting the road into a grid lattice, calculating the risk level in each grid according to the inter-vehicle relation of the two vehicles and the group energy formula of thevehicles in the target area, and obtaining a risk level thermodynamic diagram of the area. The method for evaluating the risk level of the road area is closer to the actual road condition and is moreeffective in dealing with th
