Crossing traffic signal control system and control method thereof

Abstract

The invention relates to a crossing traffic signal control system which comprises a vehicle flow rate statistic analysis module, a traffic control preemption decision module and a crossing signal lamp module which are connected sequentially. The invention also relates to a crossing traffic signal control method utilizing the system. According to the control method, based on a clock phase, the traffic control preemption decision module controls the crossing signal lamp module, when phase execution is finished, if the traffic control preemption decision module determines that a phase green light time of a phase is longer than a preset phase time, the phase is executed first to realize preempt control based on the clock phase, then the clock phase is executed according to a preset sequence, thus a phase of a high vehicle flow rate is released preferentially, city traffic pressure is effectively alleviated, and a traffic pass efficiency of a city is raised. The system and the method in the invention have the advantages of a simple system structure, low cost of method realization, and a wide application range.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to the technical field of automatic control of traffic signals, in particular to an intersection traffic signal control system and a control method thereof. Background technique [0002] With the development of productivity and social progress, problems such as traffic congestion, traffic accidents and traffic environmental pollution have become the focus of people's general attention, and such traffic problems are more prominent in cities. At present, many countries and local governments are working to find effective solutions to this problem. Therefore, on the basis of the existing intelligent transport system (Intelligent Transport System, ITS), it is necessary to explore solutions to urban traffic problems. [0003] In recent years, people have achieved fruitful theoretical results in the research of intelligent transportation systems, and some of the results have bee...

Problems solved by technology

Therefore, if the traffic control system suitable for ordinary roads is applied invariably to cities, the control effect is not ideal, and there is room for further improvement.
