Sensing can realize special functions such as phase residency and pedestrian crossing once.
The adaptive sensing control automatically adjusts the signal control parameters in real time according to the status of the traffic flow to adapt to the change of traffic flow control method.
The fixed-cycle control performs phase signal output according to a preset control scheme. During the operation of the scheme, the period length, green letter ratio and phase sequence do not change with the road conditions.
Multiple time periods are controlled at different time intervals, and the traffic conditions at the intersections are also different. In order to achieve better control effects, different control schemes should be set.
Signals can be divided into a number of periods 24 hours a day, each period running the corresponding cycle, green letter ratio program.
Dynamic scenario selection control Dynamic scenario selection control is based on the scenario selection model, and is based on the actual traffic conditions.
Single-point optimization control Single-point optimization control is a control method that optimizes cycle and green signal ratios by using real-time traffic data at intersections.
The single-point optimization control performs traffic intensity-period optimization based on the 5-minute data of the sensing and strategy detectors, and optimizes the green signal ratio based on the inflow sensing detector flow. The cycle and green letter ratio are optimized every 5 minutes. There is no transition plan when the old and new programs are converted.
Cableless coordination control Cableless coordination control is a type of line coordination control. Signals do not communicate with each other. Requires that the semaphore clock be completely synchronized and the same time period plan is implemented in the time table to perform cableless coordination control. By setting the phase difference, traffic signal coordination at each intersection is achieved.
The cableless inductive line coordination control signalling machine uses the inductive control principle to optimize the green time of each phase in real time according to the vehicle phase arrival at the key phase of the intersection, and maintains the starting point of the coordinated phase unchanged, thus ensuring the ideal intersection phase. The difference does not change, and then the main road green wave control is realized, and the purpose of the green light time of the secondary road traffic is effectively utilized.
The main function of intelligent traffic signal
The signal green time is changed in real time based on the detected traffic flow data. The phase runs at least green minimum. If there is a car passing, extend one extended green time, and continue to extend the green time until the maximum green is reached.
