Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The invention is an intelligent timing method for traffic signal lights at intersections, which is used for intelligent timing matching based on traffic flow information. The range is controlled within [Tmin,Tmax], where Tmin is 0, Tmax is 70 seconds, the following is combined with the attached Figure 1 to Figure 4 Describe its specific implementation steps:

[0036] 1) figure 1 Each of the four intersections 1, 2, 3, and 4 needs a set of cameras. figure 2 Collect the traffic flow information of the current intersection lane in the intersection detection area as shown: Determine the traffic flow fuzzy set accord...

Abstract

The invention discloses an intelligent timing method of intersection traffic signal lamps. The intelligent timing method includes the following steps: collecting intersection phase position traffic flow information in real time, determining initial releasing time of lanes of intersections according to waiting traffic flow of the lanes of the intersections, initializing intersection passage states, switching the passage lanes according to left passage time, updating passage state arrays while the new lanes are switched to carry out releasing, repeating the steps to carry out intelligent timing on the traffic signal lamps, and controlling the traffic signal lamps according to timing signals. By means of the intelligent timing method, timing control over the traffic signal lamps can be effectively carried out, seamless switching on releasing of the lanes of the traffic intersections can be achieved, and the passage rates of the intersections can be maximized.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to an intelligent timing method for traffic signal lights at intersections. Background technique [0002] With the rapid development of China's economy, the development speed of urban transportation is also getting faster and faster. But on the whole, China's traffic problems are becoming more and more serious. Traffic congestion will cause waste of resources, environmental pollution and many other problems. Cause the reason of traffic congestion to mainly contain two: one, traffic intersection traffic capacity is limited; Therefore, in the case of road conditions that are difficult to change in a short period of time, improving the traffic situation requires finding a better timing method for traffic lights. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent timing method for traffic lights ...
