A method for automatic selection of large-scale bus arterial routes based on land use

Abstract

The invention discloses a method for automatic selection of large-scale public transport trunk lines based on land utilization, the main steps are as follows: S1 simplification of the public transport network; S2 construction of a mathematical model; S3 single-objective planning and solution; S4 double-objective planning and solution; The selection method is based on the existing public transport network scheme and the passenger flow matrix of the predicted origin and destination points, and quantitatively selects routes on the basis of the existing network to overcome the difficulty of subjective design and planning schemes, the variety of station and line network structures, and many influencing factors It leads to problems such as difficulties in the selection of schemes, and improves the scientificity and rationality of public transportation route planning.

Description

technical field [0001] The invention belongs to the technical field of public transportation network planning, and in particular relates to a method for automatically selecting large-scale public transportation trunk lines based on land use. Background technique [0002] Overview of public transport route planning [0003] Public transport route planning is the prerequisite for building an efficient and reliable urban public transport system. The main purpose is to guide the reasonable setting and arrangement of urban public transport lines in a prudent manner, and ensure the functional applicability and operational efficiency of the lines. At present, many cities in China are carrying out large-scale public transportation planning or construction, providing planners with scientific and quantitative public transportation route planning methods will help reduce the workload of planners and improve the standardization and quality of route planning. scientific.

AI Technical Summary

Problems solved by technology

[0017] 1. Urban land use changes frequently, urban renewal is fast, and the old line planning scheme does not provide enough support for urban development;

[0018] 2. The preset scale of the planned route lacks traffic quantification analysis and does not consider urban expansion;

[0019] 3. In terms of rail transit, the rail layout in the urban center area has not been deeply thought out, and the lines are only evenly distributed in each development axis of the city, and the rail coverage rate in the central urban area is low;

[0020] 4. In terms of rail transit, due to the lack of stable rail network guidance, transfer conditions are basically not reserved, resulting in the subsequent stations and the first phase of the project mainly using passageways for transfers, which is inconvenient;

[0021] 5. The planning does not reserve flexibility, and the line network planning indicators are not properly selected, resulting in serious passenger flow congestion during the current peak period;

[0022] 6. The line network has a single layer, lacks urban express lines, and the difference between backbone lines and ordinary lines is not obvious

[0023] (2) Planning a section, constructing a section, operating a section, lack of integrity

[0026] 2. No transfer conditions are reserved, resulting in difficulties in the construction of transfer and connection projects between subsequent stations and preliminary projects, and insufficient transfer redundancy;

[0027] 3. The early route planning did not consider the overlapping and double-tracking issues between the early route and the later route;

[0028] 4. Under the existing domestic conventional public transportation and rail construction and operation mechanism and system, the possible problems of collinearity have not been fully considered, especially the problem of collinearity of lines at different levels;

[0030] 6. The mode of connection between the new town line and the central city line is single, and the connection mode between the new city or peripheral line of the city and the central city line or the current main line network is relatively single, and most of them are single-line connections

The biggest problem brought about by this connecting transfer mode is that the transfer point is located on the edge of the city, and there is a lack of a large number of jobs around the transfer station, so most passengers need to choose to transfer to other lines to enter the central city. and its transfer stations bring greater passenger flow and operating pressure;

[0031] 7. Insufficient transfer station capacity leads to network bottlenecks. Since some transfer stations are used as transportation hubs, segmental planning may lead to continuous addition of multiple lines to a single hub transfer station, resulting in insufficient transfer capacity of the transfer station and becoming a network bottleneck.
