The principle of road traffic signal control
- Apr 09, 2018 -

1. Set the traffic light signal control parameters at each intersection to minimize the pause delay time at the intersection at all intersections.

2. In order to meet the above conditions, it is also required to ensure the formation of a two-way green wave band when the signal is interlocked with green wave control at multiple intersections, and the green wave bandwidth is the widest.

3. Establish a traffic flow time-sharing model, such as daily time division, and establish a traffic matrix for each daily time period.

4. Solve the best timing plan for each time period.

5. Set the controller parameters according to the timing table, and ensure that it operates normally on time.

6. Re-solve the flow model reconstruction and parameter optimization seasonally.
