Road traffic signal algorithm Settings:

Typically, road traffic lights first is the length of the basis through the intersection traffic.

Is not the same as the intersection of usually is not the same, and its calculation process is relatively complicated.

Must be estimated traffic flow data, traffic query may conclude the current traffic flow and import set forms, etc. The so-called traffic flow is each hour each import to the number of vehicles in all directions, import the Settings is refers to the imported one how many straight lane, right lane, right lane and left turn lanes, etc.

Not the same intersection, signal cycle and green light time is not the same. But there are special circumstances, such as the harmonious control (green), two crossroads too close, etc.

The intersection signal control method based on control of primary can be divided into different timing control, inductive control and adaptive control. At present, however, is usually within the city road traffic signals at different time periods and the green light time is different, because of the traffic flow in different time has different characteristics.
