traffic signal tuning services

A detailed overview of traffic signal optimization services and traffic signal tuning services. Regional coordination is the overall control of traffic signal control from point to line, and then from line to surface.Traffic signal control is implemented from single-point intersection signal control to green wave belt control on one road, and finally, through multiple crisscrossing roads that realize the green wave belt, green wave belt control in the entire urban area is achieved, so that all roads are smooth and green. The effect of wave passage is to achieve the best effect of traffic signal control in the area.

Map interface: The system has its own map function. There is no need to import additional maps. Set up signal machines on the map according to actual requirements.

Simplified diagram interface: It can concisely and clearly display the road sections or areas we want to optimize, and set the parameters related to roads and intersections.

Quickly enter intersection coordinates and integrate map coordinate search functions

Integrated online and offline map functions, you can quickly enter the intersection location on the map into the system, allowing the system to automatically calculate the distance between intersections

During the calculation process, the system can lock the calculated intersection to ensure that when calculating the green wave belt in other directions, it will affect the calculation results of the previous green wave belt.

Time distance diagram interface: display the optimized road section or regional green wave belt effect diagram through different calculation methods.

Functional advantages: 

1. The regional coordination signal optimization system has low investment and quick results. It maximizes road traffic efficiency based on existing facilities and conditions;

    2. The regional coordination signal optimization system has a complete calculation process and does not require manual calculation at intersections. , to ensure calculation accuracy and save labor and working hours; 

    3. Support green wave optimization of asymmetric traffic flow, asymmetric vehicle speed, and different bandwidths on arterial roads; 

    4. Support green wave optimization of dual arterial roads at intersections;

    5. Support setting cycle range, Calculate the green wave belt effect separately and choose the best solution; 

    6. Support multiple calculation methods, and can achieve the green wave belt effect based on priority calculation, region-by-section calculation, road priority calculation, and regional priority calculation.

    7. Support dual-cycle coordination. For some intersections with small traffic between arterial intersections, when the actual operating cycle is close to half of the coordination period, dual-cycle coordination can be adopted, that is, coordination is achieved every two cycles at small intersections. ; 

     8. The optimized timing plan can be adaptively adjusted according to the original timing and the existing signal optimization system.
