Abstract

The invention provides a road intersection early warning control method and system. The road intersection early warning control method comprises the following steps that image frames and radar signalscontained in road video data at each entrance of a road intersection are detected to obtain road information at each entrance; the road information includes moving object identification information,lane line identification information, vehicle turn signal identification information, vehicle position information and vehicle speed information, wherein moving objects include vehicles, pedestrians and non-motor vehicles; the road information is calculated to obtain traveling information of the moving objects, wherein the traveling information comprises traveling paths and traveling speeds; and according to the traveling information of the moving objects, whether conflict exists between the moving objects or not is judged, if the conflict exists, an alarm is sent to the moving objects. According to the road intersection early warning control method and system, conflict prediction and early warning can be made in advance, and the safety at road intersections is improved.

Description

Technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a road intersection early warning control method and system, and a used sensing device. Background technique [0002] With the rapid economic development and the continuous improvement of living standards, the number of motor vehicles has increased rapidly. Among them, private cars are constantly influx into the limited urban transportation network, which has brought huge pressure to the urban transportation network. , Especially to the road intersections in the urban traffic network. A road intersection is the intersection of two or more roads. It is the place where vehicles and pedestrians must pass, turn and evacuate. It is the throat of the urban traffic network. Therefore, reducing congestion and conflict at road intersections is An important means to improve the safety and efficiency of the urban traffic road network. [0003] With the rise of intelligent tran...
