Arrival bus stop and departure bus stop calculation method based on urban bus GPS information

Abstract

The invention relates to the technical field of vehicle departure bus stop calculation and particularly relates to an arrival bus stop and departure bus stop calculation method based on urban bus GPSinformation. The method comprise the steps of determining whether a vehicle loses GPS caused by passing a tunnel and the like according to the real-time GPS information and vehicle line information ofa bus, performing reasonable estimation by the information of a last GPS point before the GPS loss if the vehicle loses the GPS, calculating lost GPS information to form a complete time series GPS sequence, calculating the arrival bus stop and departure bus stop information of each GPS point through an electronic fence algorithm for an updated time series GPS sequence, and finally sending the calculated arrival bus stop and departure bus stop information to a smart bus system which issues an instruction to an electronic voice station report system of the vehicle to perform accurate stop voiceannouncement. According to the method, the GPS error of the bus vehicle is reduced, the accuracy of an electronic stop voice announcement function in the smart bus system is improved, and convenienceis brought to passengers.

Description

technical field [0001] The invention relates to the technical field of calculation of departure and departure of vehicles, in particular to a calculation method for arrival and departure of stations based on urban bus GPS information. Background technique [0002] In the urban public transport system, when a bus vehicle enters a certain station, the bus driver usually makes a voice announcement to remind passengers to get off in time, so as to avoid unnecessary conflicts caused by passengers missing the correct station. [0003] The traditional bus system has not achieved complete intelligence. The bus station announcement can only be realized by manual buttons, which cannot be separated from the corresponding operation of the driver or conductor. Manual station announcement increases the driver's operating burden. The driver distracts himself from the station announcement while driving, which poses a certain safety hazard. False reporting, missing reporting, or even no rep...

AI Technical Summary

Problems solved by technology

In the current smart bus system, the electronic voice broadcast function depends on the real-time location GPS information of the bus vehicle, but in the actual urban bus operation and production, the real-time location GPS information reported by the bus vehicle to the smart bus system, due to the equipment Errors, transmission network delays and other reasons lead to a certain error between the inbound and outbound information of the actual operation of the bus and the inbound and outbound information reported to the dispatching monitoring center, and even in some areas there are GPS blind spots, that is, GPS signals Not at all, such as tunnels, underground parking lots and other areas, resulting in errors in the information of buses arriving and departing from the station, resulting in confusion in the function of electronic voice announcements
