Embodiment Construction

[0069] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0070] see figure 1 Shown is a schematic structural view of the intersection traffic signal control system of the present invention.

[0071] In one embodiment, the intersection traffic signal control system includes a traffic flow statistical analysis module, a traffic control preemption decision-making module and an intersection signal light module, and the output end of the traffic flow statistical analysis module is connected to the traffic control preemption decision-making module The input end of the traffic control preemption decision-making module is connected to the input end of the intersection signal light module.

[0072] In the method for realizing intersection traffic signal control using the system of this embodiment, the traffic control preemption decision-making module sequentially controls the intersection signal light modu...

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...
