Signal lamp self-adaptive control system and method for large park traffic safety

Abstract

The invention discloses a signal lamp self-adaptive control system and method for large park traffic safety and overcomes the defect that the fixed timing control method of large- and medium-sized park traffic signal lamps cannot flexibly adapt to park pedestrian flow change. The method includes the steps of firstly, using camera devices distributed on various road sections of a park to perform video collection, and processing images according to a set human body recognition algorithm to obtain pedestrian flow information so as to achieve pedestrian flow detecting; secondly, by a control module, judging road section busy states according to corresponding pedestrian flows, and providing corresponding signal lamp control signals; thirdly, by the signal lamps, responding to the received control signals from the control module, and controlling passing rights. The method has the advantages that the pedestrian flows of the various road sections in the park are judged, the passing rights of the road sections are controlled in real time by controlling the switching of the signal lamps at the intersections of the park, pedestrian passing requirements are satisfied effectively, and road safety is guaranteed effectively.

Description

Technical field: [0001] The invention belongs to the field of road traffic safety, in particular to an adaptive control system for traffic lights of large parks. Background technique: [0002] For a long time, experts and scholars in the field of traffic control have paid more attention to the research of urban traffic control, but there are relatively few research contents related to road traffic control in large parks (such as industrial parks, universities, large living areas, etc.). For this type of park, the roads are intricate, the traffic volume is large and the pedestrian flow is often higher than that of the roads outside the park. The mixed traffic conditions of people and vehicles make the roads in the park bear greater traffic pressure. For special time periods such as commuting and the entry and departure time periods of some large-scale activities, the flow of people in the park is relatively large, and the mixed traffic conditions at road intersections and in ...

AI Technical Summary

Problems solved by technology

This kind of traffic signal control system is suitable for the type of area where the traffic flow can be estimated and the traffic pressure is small. It cannot meet and adapt to the short-term fluctuations of traffic flow. General period, not real-time

Therefore, when the traffic flow in the park changes suddenly, the traffic efficiency is low and traffic conflicts are likely to occur, which does not meet the traffic needs of the park, which not only wastes time but also poses certain safety hazards
