Traffic light control method for straight-through bus lane

Abstract

A traffic light control method for a straight-through bus lane realizes control of the signal light through the comprehensive adoption of a photoelectric signal emitting and receiving device, a signal processor and a Bluetooth module. According to the invention, a uniform signal processor is arranged on each bus; the signal light is in point-to-point signal communication with buses within 1.5 standard bus long distance on the corresponding lane; the bus is in point-to-point communication with the adjacent bus lane; if the red light or the green light is terminated, the signal light starts working and sends signal backwards to the next bus; in such a way, until the first bus generates the value of a final counter, the value is sent to the processor of the signal light; and if the value is larger than or equal to 3, when the red light is turned on, the green light is turned on in advance, that is, the green light time is prolonged when the green light is nearly terminated. According themethod for controlling the signal light provided by the invention, the time of the bus waiting for the red light is shortened, the bus priority passing right is endowed when the green light is turnedon.

Description

technical field [0001] The invention belongs to the technical field of traffic signal devices, and relates to a traffic signal lamp control method for through-type bus lanes. Background technique [0002] With the process of modernization, the number of various types of vehicles continues to increase, leading to serious traffic congestion in some cities. And vigorously developing public transportation is one of the best solutions to solve this problem. And bus priority driving is wherein investment is few, quick effect, the scheme of green environmental protection. With the country's emphasis on bus priority, many cities have built some dedicated bus lanes. However, due to unreasonable signal cycle and signal phase settings, buses still have to obey fixed traffic light signals, so bus priority does not Not as efficient as it should have been. As a result, the number of bus passengers has not yet increased, while the number of private cars has risen sharply, so the problem...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is: the existing bus lanes are affected by the setting of traffic lights, and the effect on the priority of buses is not obvious, and the expected effect cannot be achieved
