A bus operation method that supports dynamic adjustment of routes

Abstract

The invention discloses a bus operation method that supports line dynamic station reporting and adjustment, comprising: determining the waiting stop that needs to be stopped indicated by the stop sign, obtaining the road congestion index and station coordinates of the waiting stop, and converting the waiting station coordinates As the reference coordinates of the station, the threshold value of the station announcement to be stopped is determined based on the road congestion index; the GPS positioning data is obtained at a predetermined time interval, the current coordinates of the bus are extracted from the GPS positioning data and the coordinates are corrected to determine the current station announcement Coordinates; determine the Euclidean distance between the current reporting coordinates and the station reference coordinates, and compare the Euclidean distance with the threshold of the station announcement; if the Euclidean distance is less than or equal to the threshold of the station announcement, perform the station broadcast and set the station entry Marked as having entered the station; if the Euclidean distance between the current station reporting coordinates of the bus and the station reference coordinates is greater than the exit station reporting threshold, and the entering station is marked as having entered the station, the bus exit broadcast will be performed. The bus operation method of the invention supports dynamic adjustment of routes.

Description

technical field [0001] The invention relates to the technical field of urban public transportation, in particular to a public transportation operation method supporting dynamic adjustment of lines. Background technique [0002] At present, with the continuous acceleration of the urbanization process, the role of the public transportation system in the urban transportation system is becoming more and more important. In order to meet the travel needs of passengers and alleviate the pressure of urban traffic, the bus operation method based on the communication system has gradually replaced the manual auxiliary operation method based on the bus driver or flight attendant. [0003] In the bus operation method of the prior art, the bus operation system stores the coordinates of each station in the bus operation line, and the voice and text prompt information of the arrival and pre-arrival of each station in the vehicle-mounted terminal on the bus . In bus operation, the vehicle-...

AI Technical Summary

Problems solved by technology

This calculation method cannot solve the problem of GPS coordinate drift when encountering special road sections, such as next to high-rise buildings or under urban elevated roads, and there will be a phenomenon of late station reporting; and on roads with curved tracks, there will be premature station reporting.

These factors affect the accuracy of automatic station announcement and passenger experience
