Abstract

The invention discloses a bus rapid transit arrival information release system and method accurate to the second, and belongs to the technical field of intelligent transportation application. When bus rapid transit is dispatched, a bus rapid transit vehicle provided with a vehicle-mounted GPS positioning unit and a vehicle-mounted mileage counting unit is used for driving once in advance according to a bus rapid transit line, information determined every second by the vehicle-mounted GPS positioning unit and the vehicle-mounted mileage counting unit serves as reference, a current actual position of the vehicle is directly determined in an actual running process, under the conditions that the vehicle travels to a tunnel, below an overpass and the like, GPS signals are shielded, and position data can not be output, the system determines the current position of the vehicle according to traveling mileages read by a mileage counting submodule, and accuracy of bus rapid transit vehicle dispatching is greatly improved. An electronic information display unit on a platform displays the traveling position of the bus rapid transit vehicle and simultaneously displays arrival remaining time of a latest bus rapid transit vehicle, and the remaining time can be accurate to the second.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a second-accurate rapid bus arrival information publishing system and method. Background technique [0002] Urban road traffic is the "blood vessel" of the city, and making it smooth is the guarantee for the sustainable development of the city. At present, the supply of urban road traffic is far from meeting the traffic demand, resulting in urban road traffic congestion. The causes of urban traffic congestion are multi-faceted. How to improve the efficiency of public transportation to meet traffic demand and alleviate traffic congestion is one of the main issues that traffic management decision-makers care about. [0003] Traffic demand refers to the requirements for people and things to move in various ways in social public space for various purposes. Therefore, it is the pursuit of traffic management decision makers to use transportation means with large p...
