Embodiment Construction

[0019] The present invention is applicable to the traffic flow in large cities, especially the urban roads with bus-only lanes where the bus flow is relatively large. For the bus queue in the straight direction with the number of vehicles greater than or equal to 3, the signal phase of the signal lamp is controlled to make the bus priority pass, such as figure 1 , which actually becomes:

[0020] 1. Install DSP digital signal processing equipment combined with single-chip microcomputers, Bluetooth transmission equipment, and photoelectric signal transmitting and receiving devices at large urban intersection signal lights. The DSP digital signal processing system schedules and controls the function of the corresponding timing program of signal lights. Wired connection, transfer information to each other.

[0021] 2. Each bus is equipped with a photoelectric signal transmitting and receiving device at the end to ensure that the photoelectric signal transmitting and receiving de...

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...
