Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Since the bus travels according to the established route, the bus route between two adjacent stations is the smallest division unit for the bus to travel according to the route. If the lines between two adjacent stations are abstracted and used as the atomic unit expressed by the bus traffic conditions, the calculation process of the travel time between stations can be simplified as: bus GPS data → abstract road conditions between stations (that is, the travel time delay between stations ). This not only greatly simplifies the calculation process (such as eliminating the construction of the bus floating vehicle processing system), but also can reduce the calculation error introduced in the calculation and accumulation process of the travel time of the road ...

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 bus arrival prediction method and system based on bus GPS data. Background technique [0002] With the acceleration of urbanization in our country, large and medium-sized cities have entered a period of rapid growth of motor vehicles, the contradiction between supply and demand of urban transportation 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] In order to increase the proportion of citizens traveling by public transport, in addition to improving the construction of hardware facilities such as lines and stations, it is also necessary to focus on improving the attractiveness of public transport. For most cities at present, the bus capa...
