V2X Method and System for crosswalk safety walking support for visually impaired using Vehicle to Everything

摘要

By applying V2X technology, it is possible to comprehensively determine traffic guidance information and information about approaching vehicles for the visually impaired at a crosswalk, and through this, a method of supporting safe walking in crosswalks for the visually impaired that can prevent vehicle safety accidents of pedestrians in crosswalks; system is provided. Crosswalk safe walking support system according to an embodiment of the present invention, receives GPS location information, receives signal information from a signal controller of a traffic light, and a communication unit for receiving vehicle state information from the vehicle terminal (OBU); And by collecting GPS location information, signal information, and vehicle state information, predicting the stopping position of the vehicle, and according to the prediction result, a warning message to warn a pedestrian of a dangerous situation or a gait message to induce a walking guide to a pedestrian is output. processor; including. Thereby, the vehicle stop position (stop sight distance) according to the vehicle position and vehicle speed before walking in the crosswalk is comprehensively determined, and through this, when there is an accident risk, the pedestrian (blind person) is warned, Accidents can be prevented in advance. In addition, when a walking signal or traffic light blinks, the pedestrian information (BSM) of the visually impaired is transmitted to the vehicle terminal (OBU) to inform the presence of pedestrians in the crosswalk, and blind spots and poor visibility, drowsy driving, and non-observance of forward gaze Pedestrian accidents caused by collisions can be prevented.
