Problems solved by technology

Relevant road traffic regulations strictly prohibit drivers from using mobile phones while driving, but there are no clear requirements for pedestrians to use mobile phones. The above situation has brought great challenges to the safety of pedestrians at intersections and crosswalks without signal control

Embodiment Construction

[0044] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0045] The rapid development of intelligent transportation provides technical means to solve traffic problems. Among them, vehicle-road coordination technology has become a popular technology and research focus in the field of international intelligent transportation, and European and American countries have also achieved phased research results. Vehicle-road coordination is the use of advanced wireless communication and new-generation Internet technologies to implement vehicle-vehicle and vehicle-road dynamic real-time information interaction in an all-round way, and to carry out vehicle active safety control and road coordination on the basis of full-time and spatial dynamic traffic information collection and fusion. Management, fully realize the effective coordination of people, vehicles and roads, so as to form a safe, efficient and environmentally...

Abstract

The invention provides a traffic safety pre-warning system for pedestrians using mobile phones. The system comprises mobile terminals arranged in the mobile phones of the pedestrians; on-board units arranged in vehicles; a pedestrian crossing warning light arranged on a pedestrian crossing and used for giving alarm light when receiving a pre-warning instruction sent by a road side unit; and the road side unit arranged at the roadside of a pedestrian crossing of an intersection or a road section and used for analyzing whether conflict occurs between vehicles and pedestrians according to pedestrian dynamic information and vehicle dynamic information in a radiation area, and sending the pre-warning instruction to the mobile terminals of the pedestrians and the on-board units of the vehicles, wherein the pedestrians and the vehicles may have conflict, as well as the pedestrian crossing warning light. The system is arranged on the pedestrian crossing of an unsignalized intersection or road section, so that information sharing between drivers and crossing pedestrians can be realized efficiently and safely; and a unified safety early warning judgment criteria is established, thereby making up for the dangers possibly brought about by sensory differences between the drivers and the pedestrians.

Description

technical field [0001] The invention relates to the fields of intelligent transportation, Internet of Vehicles and traffic safety, in particular to a traffic safety early warning system and method for pedestrians using mobile phones. Background technique [0002] In unsignal-controlled intersections or crosswalks, drivers and pedestrians often have traffic accidents due to misinterpretation of the intentions of both parties and miscalculation of the speed and distance of both parties. There are more and more pedestrians, and relevant studies have shown that pedestrians use mobile phones when crossing the road to distract pedestrians, ignore road and vehicle conditions, and often miss the best response time when there is an accident. The proportion of pedestrian traffic accidents to the total number of pedestrian accidents is increasing year by year. Relevant road traffic regulations strictly prohibit drivers from using mobile phones while driving, but there are no clear req...
