Abstract

The application provides a signal control method and device. The method includes: obtaining the number of queuing vehicles in the corresponding lanes of each entrance road at the road intersection; judging whether the signal phase jump condition is satisfied according to the number of queuing vehicles in the corresponding lanes of each entrance road; , then determine the signal phase to be skipped according to the number of queued vehicles in the corresponding lanes of each entrance, and control the traffic lights at the road intersection to jump to the signal phase to be skipped. By using the vehicle as the basic control unit to count the number of queuing vehicles, compared with simply counting the queuing length or traffic flow, it has higher accuracy and stronger applicability, and through the limitation of signal phase jump conditions, it can avoid too frequent Unconventional phase jumps, so using this application can improve traffic control efficiency.

Description

Technical field [0001] Technical Field The present application relates to traffic control, and particularly to a method and apparatus for controlling signal. Background technique [0002] By optimizing traffic signal control methods to improve the efficiency of traffic intersection, it is an effective way to improve urban traffic environment. [0003] Currently, using a surveillance camera provided at the entrance to the intersection, in order to obtain the queue length of the vehicle, and thus the length of each queue in accordance with a signal phase at the inlet determine the need to jump to achieve adaptive control of the traffic signal, traffic signal control such that way traffic state to adapt. [0004] However, since the camera identified vehicle is a vehicle queue length from the queue, it is limited recognition accuracy, especially when the cart passes there, resulting in the camera field of view is blocked by the identified queue length less accurate, so that the effic...
