Problems solved by technology

In this case, the traffic conditions at road intersections are ever-changing. When a certain direction is congested or multiple directions are congested, the road intersection is still controlled according to the predetermined method of traffic lights, which not only does not alleviate the traffic situation, but often leads to congestion. getting more serious

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0033] like figure 1 As shown, the urban area traffic classification induction method provided by the present invention includes:

[0034] Step 1. Detect the number m of traffic flow through the urban intersection camera and intersection sensor;

[0035] Step 2: Detect the speed v of the vehicle passing through the intersection i , acceleration a i , and the number of traffic m to estimate the delay time of a single vehicle;

[0036]

[0037] Among them, t i,j Indicates the delay time of the i-th vehicle on the j-th road segment, l j is the length on the jth road segment, v i,j is the actual driving speed of the vehicle, Indicates the expected driving speed of the vehicle in the free-flow traffic state, a i , j is the acceleration of the i-th vehicle passing thro...

Abstract

The invention discloses a city region road classification inducing method. The method comprises the steps that a bicycle delaying time change rate signal and a traffic flow change rate signal are input in a first fuzzy controller, and the traffic flow congestion grade is output; the road surface temperature and air humidity are detected, and rod surface width is combined to obtain a city road condition evaluation index; the traffic flow congestion grade and a road condition evaluation index change rate signal are input in a second fuzzy controller, the rod passage grade is output, a driver isprompted to make a detour or pass according to the road passage grade, city region roads are effectively utilized, and partial congestion is avoided.

Description

technical field [0001] The invention relates to the field of traffic classification judgment, in particular to a road classification induction method in an urban area. Background technique [0002] With the continuous advancement of the urbanization process, the number of motor vehicles has increased rapidly, and urban road congestion has become increasingly serious. In order to ensure the normal operation of vehicles between urban roads, traffic signal control at road intersections is particularly important. The traffic signal control at the intersection is mainly realized by the traffic signal controller. Therefore, traffic signal controllers play an increasingly important role in daily life. [0003] In the prior art, the control of the traffic lights at the intersection is usually controlled according to the preset time, and once the green passing time of each direction of the intersection is set, it does not change during operation. In this case, the traffic conditio...
