Urban tramcar level crossing automobile early warning system and method based on vehicle-road cooperation

The invention provides an urban tramcar level crossing automobile early warning system and method based on vehicle-road cooperation. The method comprises the steps that when a vehicle driver selects adestination in a navigation system and a navigation path is determined, a path planning module detects whether the path passes through a level crossing of an urban rail and a motor vehicle road or not; if yes, when the vehicle is driven to a certain distance away from the level crossing, a vehicle information module and an information communication module collect state information of the vehicleand the nearby tramcar respectively and transmit the state information to the analysis module. An analysis module judges and analyzes the situation according to the received information and gives a corresponding instruction. An information prompting module sends out a corresponding passage suggestion or warning prompt after receiving the instruction. According to the invention, reasonable promptsare given according to the condition information of the vehicles and the tramcars before the vehicles pass through the level crossing of the tramcar rail and the motor vehicle lane, so that the vehicles can safely and orderly pass through the level crossing of the urban rail and the motor vehicle lane.
