Abstract

The invention discloses a method for constructing a rail transit station passenger flow prediction model on the basis of network topology characteristics. The method comprises the following steps that: (1) selecting the population density, the employed population density, the economic poverty coefficient and the road length density of an administrative region to which the station belongs, a rail transit station number in a range far away from the station for 1000/700/400m, a bus station number in a range far away from the station for 100/200/500m, a distance between the rail transit station and a downtown, a betweenness, a clustering coefficient, a degree and the station entering and exiting passenger flow data of different time periods of each station as variables; (2) obtaining the dataof each variable selected in (1); (3) importing parts of data of each variable in (2) into a Poisson regression model to fit, and independently simulating station entering and exiting passenger flow prediction of different time periods; and (4) checking the prediction model by residual variable data. The method is high in accuracy and rationality.

Description

technical field [0001] The invention relates to the technical field of rail transit station passenger flow forecasting, in particular to a method for constructing a rail transit station passenger flow prediction model based on network topology characteristics. Background technique [0002] With the development of society and economy, the number of cars in the society is increasing year by year, and the limited road resources and the pressure of use are gradually increasing. More and more cities are beginning to choose to develop large-capacity public rail transportation. Good transportation environment, large transportation volume, fast speed and other characteristics have gradually become the main body of transportation in some cities. At the same time, how to accurately predict the passenger flow and station size of rail transit stations has become a research hotspot in this field. At present, domestic and foreign rail transit station passenger flow forecasting is mainly ...
