Intelligent fine-grained control system and method for right-turning vehicles and pedestrians crossing the street in the same phase

Abstract

The invention relates to an intelligent fine-grained control system for right-turn vehicles and pedestrians crossing the street in the same phase. The referenced green light on the straight lane in the same direction is defined as the green light for straight ahead, and is characterized in that it also includes: signal phase detection equipment; right-turn vehicle detection equipment for detecting the queuing length of vehicles on the right-turn lane; pedestrian detection equipment. Another technical solution of the present invention is to provide an intelligent and fine-grained control method for right-turning vehicles and pedestrians crossing the street in the same phase. The invention finely divides the timing of going straight according to the green light, and reasonably gives right-turning vehicles and pedestrians crossing the street the right of passage, which not only ensures the needs and safety of pedestrians crossing the street, but also takes into account the traffic efficiency of right-turning vehicles.

Description

technical field [0001] The invention relates to an intelligent fine-grained control system and method for right-turning vehicles and pedestrians crossing the street in the same phase. Background technique [0002] With the continuous development of the social economy, the number of motor vehicles continues to rise, and the chaotic problem of people and vehicles at urban intersections has become increasingly prominent. On the one hand, there are conflicts between pedestrians and right-turning vehicles in both space and time, which easily lead to frequent traffic accidents. On the other hand, due to the policy of giving way to pedestrians and the status of vulnerable groups of pedestrians, motor vehicles sometimes have to stop frequently, which affects the traffic flow capacity. . [0003] At present, the urban intersection signal control system mainly formulates signal timing schemes from the perspective of motor vehicles, and under normal circumstances, the right turn lane ...

AI Technical Summary

Problems solved by technology

However, the duration of the green light for pedestrians under this approach is relatively fixed, so it cannot match the fluctuation of the number of pedestrians crossing the street well; and there is a serious right-of-way conflict between right-turning vehicles and pedestrians crossing the street during this green light phase

[0004] The current signal timing scheme for right-turning vehicles and pedestrians has the following problems: (1) When the pedestrian signal light turns green, a large number of pedestrians waiting to cross the street gather to cross the street. Passing forcibly endangers the personal safety of pedestrians crossing the street; (2) During the final period of the green light of the pedestrian signal light, there are fewer pedestrians crossing the street. At this time, motor vehicles are likely to form a continuous traffic flow, and very few pedestrians cross the street. ability, on the other hand, it endangers the safety of pedestrians
