Embodiment Construction

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

[0017] A GPS-based BRT vehicle positioning and traffic signal control method and device designed by the present invention realizes a traffic signal control system with priority and rapid passage when BRT vehicles are at traffic intersections or shared public areas. This device adopts the technology of combining the continuity and real-time positioning of GPS with 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 automatically sends the dynamic location information of the BRT vehicle in real time. When passing through each intersection or public area, the information is received by the ground receiving and processing device installed in the traffic signal controller. The ground receiving and pr...

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, and calculates 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 traffic for urban BRT vehicles, and specifically relates to a GPS-based BRT vehicle positioning and traffic signal control method and device. Background technique [0002] With the expansion of my country's urban construction scale and the increasing number of vehicles, public transportation is of great significance to guide 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, high engineering difficulty and many problems faced by subways and light rails, not every city has the ability implemented in a short period of time. The BRT system with less investment, quick results and short construction period will be one of the best choices to improve the service level and operation ef...
