A Method for Predicting the Arrival Time of Buses Based on Historical Data

Abstract

A public transport vehicle arrival time prediction method based on history data comprises the following steps: a)receiving GPS real-time data uploaded by a GPS device on a public transport vehicle and vehicle arrival information data in real time; b) processing the GPS real-time data after the GPS real-time data of the vehicle is obtained successfully; and c) after the vehicle arrival information is obtained successfully, searching station devices to send information from on-line station devices according to the line serial number and the running direction in the vehicle arrival information and obtaining the closet vehicle distance of a target station; and through obtaining the history data and today's data of the running speed of a vehicle between adjacent stations on the line at set time running period, by utilizing a weighted average method to estimate the average running speed of the vehicle between the adjacent stations on the current line and at the current time period, and on the basis of the bypassed inter-station distances and inter-station average running speed of the vehicle running to the station, each inter-station running time of the vehicle can be estimated, and the vehicle arrival time can be predicted jointly. With the method, the prediction distance is long, the real-time performance is good and the accuracy is good.

Description

technical field [0001] The invention relates to the technical field of intelligent public transport, in particular to a method for predicting the arrival time of public transport vehicles. Background technique [0002] The development of public transportation is one of the important ways to alleviate traffic congestion in large cities in my country. Improving the service level of public transportation will greatly improve the efficiency of traffic operation. The electronic stop sign on the platform is the most widely used public transportation infrastructure, which can provide passengers with timely Vehicle arrival information greatly facilitates the travel of passengers. With the continuous acceleration of my country's urbanization process and the continuous improvement of public transportation, the number of bus stop signs is increasing. Quality is very important. [0003] Existing vehicle positioning technologies include bus positioning technology based on CAN bus, bus pos...
