Abstract

The invention belongs to the technical field of an ITS (intelligent traffic system), in particular to a device and method for controlling speed of a BRT (bus rapid transit) with a bus exclusive lane. The device comprises a vehicle-mounted GPS (global position system) positioning module, an RF (radio frequency) wireless transmission module, a signal period time meter, a vehicle-mounted MCU (micro control unit), a display screen and a voice prompt device; the running speed range of the BRT at green light time regions between two adjacent crossing roads is calculated through the vehicle-mounted MCU by using the device, and a driver is reminded of controlling the speed within a running speed range as so to pass a level crossing intersection smoothly within the green light running time. The green light is on all the way under the condition that the signal lamp cycle period at the crossing road is not interfered and the traveling orders of other vehicles at normal operation are not disrupted, the stand-by time at the crossing roads of the BRT is eliminated, the aim of high speed, large traffic volume and arrival on schedule of the BRT is realized, the running quality and efficiency of the BRT are optimized, the stoppage at an intersection is eliminated, environmental pollution and energy consumption caused by the set-up procedure are reduced.

Description

1. Technical field [0001] The invention belongs to the technical field of ITS intelligent transportation systems, in particular to a vehicle speed control device and method for BRT express buses with bus lanes. 2. Background technology [0002] The patent authorized by the China Intellectual Property Office is CN101256717A, a patent titled "A GPS-based BRT vehicle positioning and traffic signal control method and device", which proposes to realize the signal priority of urban BRT by adjusting traffic lights to reduce The time delay in the operation of BRT vehicles and the purpose of realizing the priority of BRT vehicles. [0003] The BRT vehicle positioning and traffic signal control device disclosed in this patent is composed of GPS and MCU modules installed on the BRT vehicle, RF wireless transmission module, MCU module installed in the traffic signal control machine and other devices. The vehicle-mounted GPS device sends the obtained BRT position information to the grou...
