Bus arrival prediction method and system based on bus GPS data

Abstract

The invention discloses a bus arrival predication method and system based on bus GPS data, and belongs to the field of intelligent transportation. The bus arrival predication method includes the steps of reading in topological data of bus stations, building a topological relation of the bus stations, receiving the bus real-time GPS data, and obtaining and outputting in-station delay, inter-station delay and next-station arrival delay, of buses in various lines, in the topological relation according to a set time interval. The bus arrival predication system comprises a topological relation building device, a GPS data reading module and a bus running model building device. According to the bus arrival predication method and system based on the bus GPS data, due to the fact that the calculating process of the running time between stations is simplified to be achieved through the bus GPS data and the inter-station abstract road conditions, the calculating process is greatly simplified, and calculating errors introduced in the road section running time calculating and accumulation processes can be further reduced correspondingly. In addition, the delay of the buses inside the stations serves as a parameter to be described, and therefore the bus arrival time can be accurately calculated.

Description

Technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and system for predicting bus arrival at a bus stop based on bus GPS data. Background technique [0002] With the acceleration of my country's urbanization process, major and medium cities have entered a period of rapid growth of motor vehicles. The contradiction between urban traffic supply and demand has become increasingly prominent, and problems such as traffic congestion and environmental pollution have become increasingly serious. In this context, major cities have prioritized the development of public transportation as a key measure to alleviate traffic problems. [0003] To increase the proportion of citizens traveling by public transportation, in addition to improving the construction of hardware facilities such as lines and stations, it is also necessary to focus on increasing the attractiveness of public transportation. For most of the current cities, the l...

However, the current system does not take into account the delay of the bus in the station, and also introduces calculation errors to the final arrival time prediction.
