Way of Working

1. Central platform remote control mode

Access to the intelligent traffic integrated management and control platform to realize the remote control of the central platform. The control management personnel can use the signal control system software of the monitoring center computer to optimize the control system adaptively, preset multi-stage fixed timing, manual direct intervention control, etc. way to directly control the signal timing at intersections.

2. Multi-period control mode

According to the traffic conditions at the intersection, each day is divided into several different time periods, and different control schemes are configured in each time period. The signal machine selects the control scheme for each time period according to the built-in clock to realize reasonable control of the intersection and reduce unnecessary green light loss.

3. Coordinated control function

In the case of GPS time calibration, the signal machine can realize the green wave control on the preset main road. The main parameters of the green wave control are: cycle, green signal ratio, phase difference and coordination phase (coordination phase can be set). The Networked traffic signal controller can implement different green wave control schemes at different time periods, that is, the green wave control parameters are set differently at different time periods.

4. Sensor control

Through the traffic information obtained by the vehicle detector, according to the preset algorithm rules, the timing length of each phase is allocated in real time to obtain the highest clearance efficiency of vehicles at the intersection. Inductive control can be implemented for all or part of the phases in a cycle.

5. Adaptive control

According to the status of traffic flow, the signal control parameters are automatically adjusted online and in real time to adapt to the control mode of traffic flow changes.

6. Manual control

Toggle the manual control button to enter the manual control state, you can manually operate the networked traffic signal controller, and the manual operation can perform step operation and direction hold operation.

7. Red Control

Through the all-red control, the intersection is forced to enter the red forbidden state.

8. Yellow flash control

Through the yellow flash control, the intersection is forced to enter the yellow flash warning traffic state.

9. Power board takeover mode

If the main control board fails, the power board will take over the signal control mode in the fixed-period mode.
