Embodiment Construction

[0016] The technical solution of the present invention will be further described below through specific embodiments according to the accompanying drawings of the specification.

[0017] The GPS-based BRT vehicle positioning and traffic signal control method and device designed in the present invention realizes a priority and fast traffic signal control system when BRT vehicles are at traffic intersections or shared public areas. This device uses the technology that combines GPS continuity, real-time positioning and RF wireless transmission.

[0018] The system composition of this device is as follows figure 1 Shown. The vehicle-mounted device installed on the BRT vehicle sends the dynamic position information of the BRT vehicle in real time and automatically. When passing through various intersections or public areas, the information is received by the ground receiving and processing device installed in the traffic signal control unit. The ground receiving and processing device Ef...

Abstract

The invention relates to a rapid public bus positioning method and device based on GPS technology. The device is an vehicle device composed of modules such as a GPS, a MCU and a RF wireless transmission on a BRT vehicle to send the BRT vehicle positioning information obtained in real time and automatically to a ground receiving and processing device mounted in the communication signal controller via the RF wireless transmission module. The ground receiving and processing device processes data information related to the two positions of the BRT vehicle and the communication signal obtained, andcalculates relative position coordinate, distance and vehicle steering direction between the BRT vehicle and the ground receiving and processing device. Then the information is transmitted to the communication signal controller in real time and automatically, then switching the communication signal at crossing in time and effectively by the communication signal controller, preferably giving way to the BRT vehicle, which ensures prior and rapid pass of the BRT vehicle and exerts greatly superiority of the BRT.

Description

Technical field [0001] The invention belongs to the technical field of ITS (Intelligent Transportation System), and is a traffic signal control system that provides priority access for urban rapid transit system (BRT) vehicles, and specifically relates to a method for positioning and traffic signal control of rapid transit BRT vehicles based on GPS technology And device. Background technique [0002] With the expansion of urban construction in my country and the increasing number of vehicles, public transportation is of great significance to guiding the sustainable development of cities. Although subways and light rails play an important role in the public transportation systems of major cities, due to the large investment in subways and light rails, the high engineering difficulty, and the many problems they face, not every city has the capability. Implemented in a short period of time. The BRT system with low investment, quick results and short construction period will be one...
