Advantages of traffic signal control method:

1. Facilitate pedestrian access

If the traffic signal is planned and set up the pedestrian signal, then the traffic of the signal will be more than the signal without the signal.

The distribution of road rights is reasonable

Using traffic signal to control intersections, the distribution of road rights is more fair, reasonable and efficient than other manipulative methods. For example, when the vehicle is used to control or annular maneuver, it is necessary for the vehicle to enter the main traffic flow to find a suitable space for the vehicle, and then the demand will take a long time to wait. The use of traffic light control ensures that the driver has a special time slot.

3. Cut right angles and conflicts

Under normal circumstances, traffic signal control can be used to reduce the incident of a right Angle collision. If left to the left vehicle alone, then the left vehicle side will also be reduced.

4. The driver should not be self-reliant

Traffic light compared with other control methods, able to clearly inform you driver way distribution, drivers do not need to distinguish way distribution, simply pass when parking at a red light, green light, usefully dropped down the driver make error identification probability.

5. Be able to control each other's traffic flow

Traffic lights are different in different directions and different kinds of traffic flow can carry out orderly distribution of control. It can be useful to transform traffic flow from disorder to order, and then reduce traffic resistance, enhance traffic safety, and improve the capacity of pass-through.

6. Can control and manage the interpenetration of large traffic flow

Traffic signal control can be used to control the traffic flow situation, such as: multi-channel penetration. On the contrary, only the traffic control of the branch road can be used to control the traffic, which can cause traffic violation and traffic safety problems。
