Embodiment Construction

[0070] Below in conjunction with accompanying drawing and specific embodiment the technical scheme is further described as follows:

[0071] A calculation method for urban rail transit passenger flow density index, the steps comprising:

[0072] 1) Taking the monitoring data of passenger flow monitoring equipment at urban rail transit stations as input, the basic time granularity station density index is obtained through calculation;

[0073] 2) Taking the basic time granularity station density index as input, calculate the short-term station density index;

[0074] 3) The short-term station density index and the section line full load rate are used as input to calculate the short-term line density index;

[0075] 4) The short-term line density index of each line in the rail transit network is used as input to calculate the short-term network density index;

[0076] 5) Taking the basic time granularity station density index, short-term line density index and short-term netwo...

Abstract

An urban rail transit passenger flow density index calculating method is a station, line and network density index calculating method for establishing different time grains on three levels of point, lines and faces. Comprehensively considering the density factors, influencing station density indexes, of key areas, a station density index model is obtained after a reasonable threshold value is set with the ratios of passenger flow of each area within different time durations to the total passenger flow as the weights according to the ratio of the weighting of management objects larger than the threshold value to the weighting of all management objects; comprehensively considering the influences of stations and intervals, a density index model on the level of lines is obtained through the weighted sum of different weights of the stations and the intervals, wherein the station part includes the ratio of the weighting of all stations, larger than the set threshold value, on the lines to the weighted sum of all the stations, and the interval part includes the average value of interval load factors of the intervals on the lines; a density index calculation model on the level of networks is obtained through weighting of density indexes of all the lines, wherein the weighting includes the ratio of the passenger flow of the lines and the passenger flow of the networks. By means of the method, the congestion conditions of the stations, the lines and the networks of an urban rail transit can be truly reflected.

Description

technical field [0001] The invention belongs to the field of urban rail transit, in particular to a calculation method for evaluating passenger flow congestion index of urban rail transit. Background technique [0002] With the rapid development of intelligent transportation systems, the road traffic congestion index has become an important means of road traffic management in many cities at home and abroad, and plays an increasingly important role in government decision-making and industry management. Beijing, Shanghai, Shenzhen and other cities have studied the road traffic congestion index with different definitions and different algorithms, and achieved good results after release. The concept of density is usually used to reflect the congestion degree of urban rail transit. There is not yet a mature system of achievements in this area at home and abroad, and there are not many studies on the density index of urban rail transit. [0003] After the rapid development of my ...
