Traffic safety early warning method and device and system comprising device

Abstract

The invention relates to a traffic safety early warning device. The device comprises a map database pre-stored with information related to a road environment. The device further comprises an information acquisition module, a collision probability estimation module and an early warning module, wherein the information acquisition module is used for acquiring information related to a current runningstate and information related to a current moving state of a road user; the collision probability estimation module is used for calculating the collision probability between the vehicle and the road user; and the early warning module is used for transmitting early warning instructions on different levels to the road user and / or the vehicle according to the collision probability calculated by the collision probability estimation module. The invention further relates to a traffic safety early warning system comprising the device, and a corresponding traffic safety early warning method.

Description

technical field [0001] The present invention relates to the field of road traffic safety, more specifically, the present invention relates to a traffic safety early warning method, device and system including the device. Background technique [0002] Since the real-time position of pedestrians on or near the road is not fixed, and their action direction cannot be predicted, there is a potential collision risk for vehicles on the road. [0003] In order to avoid pedestrians, drivers usually need to stop the vehicle to wait for pedestrians to pass, and the driver and pedestrians cannot communicate smoothly, usually only rely on gestures to signal pedestrians to pass, which causes unnecessary time costs for both parties and increases Risk of traffic jams. [0004] Furthermore, besides pedestrians, the protection of other Vulnerable road users (Vulnerable road users, VRUs) such as cyclists, motorcyclists is an ongoing topic in vehicle development. Especially for special pedest...
