Embodiment Construction

[0042] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0043] In the practical application of the present invention, the vehicle detector can be used to detect the traffic flow at the entrance of each lane at the intersection, and the traffic flow data can be uploaded to the signal control machine or the background in real time, and then the signal control machine 2 can calculate the average saturation of the lanes at the intersection. degree X, traffic lights are controlled according to the size of the average saturation degree X. Its vehicle detector can use a microwave detector, and the microwave detector adopts the way of forward installation, which is based on a large-area tracking detection method: its radar antenna will continuously emit radar microwave beams and project them on the...

Abstract

The invention discloses a signal lamp self-adaptive control method based on road intersection average saturation, which solves the flaw of the signal lamp control method in the range of the 0.5<=X<=9. The signal lamp self-adaptive control method disclosed by the invention comprises steps of setting a statistics time period T2, wherein the statistics time period T2 comprises m signal periods, defining average phase saturation X<->, wherein the average phase saturation X<-> is the average phase saturation of the phase in the time period T2, determining a regulation mode for green light distribution time g according to the average phase saturation. The signal lamp self-adaptive control method based on the road intersection average saturation considers the regulation of green light time distribution during a certain time period, guarantees the stability of the system and the smoothness of the traffic at the intersection, effectively utilizes the green light time to reduce the stop delay and improve the traffic capacity.

Description

technical field [0001] The invention relates to the technical field of signal lamp control, in particular to an adaptive control method for signal lamps based on the average saturation of road crossings. Background technique [0002] At present, the most widely used and mature intelligent signal control system in the world mainly includes SCOOT (SplitCycleOffsetOptimizingTechnique), Sydney Adaptive Traffic Control System SCATS (Sydney CoordinatedAdaptiveTrafficSystem) and traffic network research tool TRANSYT ( TrafficNetworkStudyTool) and other systems. Among them, the phase of the SCOOT system cannot be automatically increased or decreased, and the phase sequence cannot be automatically changed. It is quite cumbersome to install and debug on site, and the control effect is not ideal for traffic conditions where the traffic volume is close to saturation or already saturated; the SCATS system does not have a real-time traffic model. Instead, signal control parameters are se...
