Problems solved by technology

However, such a pre-calculated travel route cannot reflect the actual operating status of the route network, because the actual operating status of each station in the route network will change dynamically due to various reasons, and the pre-calculated influence selection probability The factor of will change with time or special state, so the measured path and path selection probability are inaccurate

Embodiment Construction

[0023] The technical solution of the rail transit travel route estimation method and system will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to make it more clear.

[0024] Such as figure 1 Shown, in one embodiment, a kind of rail transit travel path estimation method comprises the following steps:

[0025] Step S102, obtaining connected paths according to the origin and destination of the trip.

[0026] For example, the starting point of travel is Xiangmihu Station, and the destination is Huaxin Station. The connecting path from Xiangmihu Station to Huaxin Station is route 1: Take Line 1 for 2 stops to Exhibition Center Station, then transfer to Line 4 Line 2 to Children's Palace Station, then transfer to Line 3 for 2 stops to Huaxin Station; Path 2: Take Line 1 for 1 stop to Shopping Park Station, then transfer to Line 3 for 4 stops to Huaxin Station. From 6:00 to 22:30, both path 1 and path 2 are connected, an...

Abstract

The invention relates to a rail transit trip path estimation method and system. The method comprises the following steps: acquiring a communication path according to a starting place and destination of the trip; selecting a valid path from the communication path; building a trip impedance function according to trip impedance factors, and calculating out a trip impedance according to the trip impedance function, wherein the trip impedance factors comprises a transfer factor, a transfer time, a trip time, a trip factor and a crowding degree, and the crowding degree is an average of a real-time crowding degree and a historical crowding degree; and substituting the trip impedance in a pre-built probabilistic model to calculate out a selection probability distribution of the valid path. The rail transit trip path estimation method and system provided by the invention, can amend trip impedance function by amended crowding degree parameters obtained based on the real-time crowding degree and the historical crowding degree by calculating, the calculated out trip impedance has timeliness and is more accurate, and accordingly, the path selection probability distribution obtained based on the trip impedance is more accurate.

Description

technical field [0001] The invention relates to computer application technology, in particular to a method and system for estimating rail transit travel routes. Background technique [0002] The urban rail transit industry is developing rapidly. More and more rail transits have developed from single-line independent operation to multi-line operation. Multi-line operation can facilitate pedestrians to choose different routes to reach the same destination according to travel time and congestion conditions. [0003] Traditionally, the path selection probability distribution of pedestrians from one place to another is measured by pre-calculating the path from any origin to destination in the route network and the selection probability of each path. However, such a pre-calculated travel route cannot reflect the actual operating status of the route network, because the actual operating status of each site in the route network will change dynamically due to various reasons, and the...
