Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide an intelligent control method for intersection signal lights. In the set area, it is only necessary to judge whether there is a car or no car in the identified road section of the road area, and then perform corresponding control, which can effectively solve the problem. The problem of inflexibility in the fixed mode ensures the effectiveness of the fixed mode and reduces waiting time, thereby improving traffic efficiency, reducing emissions and idling fuel consumption

Embodiment 1

[0030] Embodiment 1: as figure 1 Shown, a kind of intersection signal light intelligent control method, comprises the following steps:

[0031] Step1: Set and obtain the speed limit value v=50km / h of the roads in each direction at the intersection at the current moment, and the countdown duration t in the fixed mode 1 =10s and the straight travel duration Ts=40s and the left turn duration Tl=20s under the fixed mode;

[0032] Step2: Divide the roads in each direction of the intersection into buffer road sections, identified road sections and non-identified road sections;

[0033] (1) Buffer road section Sbf: the distance from the intersection center point to the opposite direction of traffic is Sbf, which is calculated as follows:

[0034] Sbf=v*t 1 =50km / h*10s=139m

[0035] (2) Recognition of road section Sia: the distance from the end of the buffer road section to the opposite direction of driving is Sia, t 2 is the time for the vehicle to pass through the Sia section, ...

Abstract

The invention relates to an intelligent control method for traffic signal lamps, which belongs to the field of traffic signal lamp control. The invention divides the roads in each direction of the intersection into buffer road sections, identification road sections and non-identification road sections. car, start the countdown in this direction in advance, and then enter the next control phase of the signal light. The invention can effectively solve the problem of inflexibility and low efficiency in the fixed mode, and ensures the effectiveness of the fixed mode, reduces waiting time, thereby improving traffic efficiency, reducing emissions and idling fuel consumption.

Description

technical field [0001] The invention relates to an intelligent control method for traffic signal lamps, which belongs to the field of traffic signal lamp control. Background technique [0002] At present, the control methods of urban intersection signal lights are all based on the fixed duration control mode (hereinafter referred to as the fixed mode), which is characterized in that no matter whether there is a car or no car on the road in each direction of the intersection, the signal lights are controlled according to the set duration. Take control to indicate the vehicle to go or not to go. [0003] At intersections with congested vehicles (city center or bustling traffic section or traffic rush hour), the control of this fixed mode should be said to be effective. But at intersections with few vehicles (urban construction new districts or non-busy sections of traffic or off-peak periods of traffic), this control method is effective but inefficient. [0004] At intersect...
