Road section pedestrian crossing signal dynamic optimization control system and method

Abstract

The invention provides a road section pedestrian crossing signal dynamic optimization control system and method. The system comprises an information acquisition module, an information processing module and an information control and release module. The information acquisition module is used for acquiring a signal lamp color state and road section traffic participant information and sending the information to the information processing module; the information processing module is used for processing the collected information, generating a signal lamp control strategy and sending the signal lamp control strategy to the information control and release module; and the information control and release module is used for receiving the control strategy and scheme from the information processing module and controlling the color of a signal lamp and a sound sensor to work. Signal lamp induction control is achieved by detecting the traffic flow and the pedestrian flow in real time, the passing requirements of motor vehicles and pedestrians are considered, and the crossing efficiency of the pedestrians is improved.

Description

technical field [0001] The patent of the present invention relates to the fields of traffic control and management technology and traffic safety technology, in particular to a system and method for dynamic optimization control of signals at crosswalks in road sections. Background technique [0002] The green light duration of pedestrian crossing signal lights should be sufficient for pedestrians waiting to cross the street safely at one time, and the waiting time of pedestrians crossing the street should not be longer than 90 seconds. Pedestrians, as the main body of slow-moving traffic and vulnerable groups in traffic activities, often fail to effectively meet their crossing needs. Therefore, how to improve the efficiency of pedestrian crossing and ensure the safety of pedestrian crossing is the key work of urban road traffic management. [0003] At present, the pedestrian signal light control method is mainly based on timing control. This control method may cause the foll...

AI Technical Summary

Problems solved by technology

[0003] At present, the pedestrian signal light control method is mainly based on timing control. This control method may cause the following three problems: 1. When the traffic flow is small, pedestrians wait too long for the red light. 2. When the pedestrian flow is large, the signal light time is not long enough; 3. Pedestrians crossing the street The status of the signal light turns red on the way, resulting in a second crossing

However, the button-type street crossing facilities have single functions and no information feedback, and the use awareness and intelligence are not high. Pedestrians often ignore the street-crossing buttons and directly run the red light, which is likely to cause traffic accidents.
