Connection characteristic analysis method based on rail station

Abstract

The invention discloses a connection characteristic analysis method based on a rail station. The connection characteristic analysis method adopts a mode of combining data with field investigation; through data analysis of planned rail stations, rail networks, planned lands and residence / employment population, and in combination with questionnaire survey of existing operation rail stations, predictive analysis of connection demand proportions of the planned rail stations in different service ranges, in different circle layers, at different station entry and exit ends and in different traffic modes is realized. A planned track station is taken as a center and combines with Thiessen polygon for analysis and identifies a rail station connection service area range, Analyzing results of different distances and different traffic connection mode proportions are investigated on site according to residential population and employment population pairs covered by the service area; more scientifictrack station connection scale and proportion measurement and calculation data of different traffic modes are formed, and a better quantitative analysis method is provided for optimization of the construction scale of connection facilities around the track station and the position of the track line.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for analyzing connection characteristics based on rail stations. Background technique [0002] Rail transit is the main mode of urban travel. For a long time, the integrated connection planning of rail stations, rail network, and ground transportation has been an important part of rail transit planning. Among them, the characteristics of passenger flow and connection methods of rail stations Research is a top priority. [0003] At present, the analysis of the connection mode ratio of rail stations is mostly to classify the planned rail stations according to their functions, such as dividing rail stations into residential stations, transportation hub stations, commercial district stations, and general stations. At the same time, based on the investigation data of the connection mode of stations with similar functions on the operating rail lines, an analogy method is...

Problems solved by technology

Although this analysis method is based on the existing track survey data, there are still the following problems: 1. The analysis of track site types is subjective. For built-up areas with mixed land functions, the division of track site types has certain limitations. Difficult and difficult to adopt a unified standard; 2. In different regions and different locations, the connection between the rail station and the rail station is different due to the size of the service area and the size of the surrounding residence / employment. If you use the direct analogy method, you can directly use the existing rail station to transfer The characteristic data is used as the connection characteristic data of the planned station, which is very likely to produce large errors; 3. The connection mode data and the proportion data of each connection mode of the rail station have not been differentiated between the in-station transfer mode and the out-station transfer mode , there will be errors in the calculated results; 4. Under the influence of different connection distances, the proportion characteristics of different connection methods at rail stations will change. Mainly bullet trains and public transport, it is unreasonable to use the analogy method to determine the connection ratio of rail stations without considering the connection distance directly; It is necessary to take into account the influence of nearby orbital sites, which is not considered by traditional analysis methods
