Abstract

The invention discloses a method and device for adjusting lanes and signal lamp periods based on vehicle queue lengths. The method comprises the following steps that a video detecting device detects the instantaneous vehicle queue lengths of respective lanes; an analyzing unit calculates the average queue lengths of respective lanes with different lane attributes within set time; the analyzing unit calculates a ratio of the average queue lengths of respective lanes with different lane attributes; and a control unit adjusts a corresponding lane attribute or the corresponding period length of a corresponding signal lamp according to the ratio of the average queue lengths of respective lanes with different lane attributes. The method and device for adjusting lanes and signal lamp periods based on the vehicle queue lengths improve the passing efficiency of an intersection by means of the variable lanes and the variable signal lamp phase periods.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for adjusting the cycle of a lane and a signal light based on the vehicle queuing length. Background technique [0002] With the development of economy, the phenomenon of urban road congestion is also becoming more and more serious. Intersections are the bottleneck of urban roads, and the traffic efficiency of vehicles at intersections directly affects the traffic efficiency of the entire urban road. [0003] In the 1970s, foreign developed countries developed representative adaptive control systems such as SCOOT and SCATS, which have achieved certain results in reducing the number of stops and improving the efficiency of intersection traffic. In the domestic existing technology, in the invention patent application with the publication number CN1441369A and the invention name "Traffic Control Law and Facilities", according to the preset or automatic induction c...
