Description

Method for determining construction scale of head and tail stations of matched buses
Technical Field
The invention belongs to the field of urban traffic planning, and particularly relates to a method for determining the construction scale of a head station and a tail station of a matched public transportation.
Background
The prior development of urban public transportation is an important means for improving the utilization efficiency of road traffic resources and relieving urban traffic jams, and is also a necessary requirement for improving urban living environment and promoting urban sustainable development. The public transportation station is an important infrastructure of conventional public transportation, and is effectively provided with important functions of guaranteeing operation of public transportation vehicles, optimizing public transportation networks, improving urban public transportation service quality and enhancing public transportation travel attractiveness. However, the urban bus station construction in China has the problems of lack of land, difficulty in implementation of planning land and the like for a long time.
The bus head and the bus tail stations can be divided into bus head and tail stations which occupy the land independently and are matched with other buildings for construction. At present, many urban land uses enter the stock development stage, and under the background of land use high-strength development, the traditional independently occupied bus station building mode faces the problems of difficult land implementation, intensive land use and the like, and the land use needs are more difficult to guarantee. The matched construction of the first and the last buses refers to a mode of combining civil building construction projects such as city updating, guaranteed housing, large development projects and the like to form matched construction of the first and the last buses and related facilities in the range of land red lines, and the method is a bottom-up bus station implementation method. The matched bus head and tail stations have the advantages of low dependence on land, close combination with land and passenger flow distribution and the like, so that the problem of difficulty in land implementation of the bus head and tail stations can be solved, the bus head and tail stations can be closely combined with the bus passenger flow, the accessibility of buses is improved, and high-quality bus service from door to door is realized.
At present, the construction mode of public buildings such as houses, businesses, offices and the like for constructing public buses and stations is explored in part of domestic cities. The related requirements of public transportation first and last station construction are met when the cities of Shenzhen, guangzhou, xishan, zhanzhou, zhanjiang, yangtze, yangbuck, kunshan and the like go out, and the public transportation first and last stations are required to be built in a matched mode when new (changed and expanded) transportation hubs, residential communities of more than 2 ten thousands people, commercial centers, industrial concentration areas, tourist attractions, schools, hospitals, large public places and the like are built. The transportation department issues "urban public electric bus station configuration Specification (JT/T1202-2018) in 5 months of 2018, which specifies the general requirements of civil buildings and transportation hubs for configuring public electric bus parking lots, first and last stations, intermediate stations and hub stations, and the construction scale and construction content requirements of public electric bus station configuration sites.
In general, the configuration specification of urban bus and electric field stations (JT/T1202-2018) and the related configuration specification or standard of each place only give the starting threshold value of the bus head and end stations to be configured, namely, how large area the building needs to be configured, the specification is simpler, and the starting threshold value to be configured and the calculation model or method of the scale to be configured are not given. In fact, whether the first and last buses are required to be built in the building is influenced by various factors such as whether the first and last buses in the block are sufficient, whether the peripheral bus lines can provide enough residual passenger capacity, whether the building can provide the first and last buses with a certain scale, and the like, so that the method is a relatively complex decision process. The inventor researches for a long time to find that if a calculation method for building the construction scale of the first and last buses can be built, and a quantitative relation between the demands and the supplies is built according to the actual situation of the demands and the supplies of the buses in the areas and the buildings, whether the first and last buses are built and how large-scale first and last buses are built by combining the buildings can be scientifically determined through interactive feedback of the demands and the supplies.
