Open service area site selection distribution method

Abstract

The invention relates to an open service area site selection distribution method, which comprises the steps of S1, calculating an influence radius R of the expressway; S2, determining layout alternatives of a target expressway service area, building a site selection model based on the maximum flow, and solving the built site selection distribution model so as to form a plurality of layout alternative schemes of the target expressway service area; S3, optimizing the plurality of layout alternative schemes of the target expressway service area, and determining a final layout scheme. According to the open service area site selection distribution method, influence factors and site selection principles for determining open service area site selection are analyzed by applying a regional transportation economic theory and a operational research planning theory on the basis of predicting target expressway transportation development and service area social demand, a qualitative and quantitative combination method is adopted, and optimization analysis is carried out on the plurality of layout alternative schemes after the layout alternative schemes are determined, so that unceasing transformation and reconstruction caused by unreasonable design of service area planning are effectively avoided, and a purpose of saving resources is achieved.

Description

technical field [0001] The invention relates to a layout planning method for expressway service areas, in particular to a site selection and distribution method for open service areas. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and has achieved great results in terms of total facility scale, transportation capacity supply, and service quality. Transportation has begun to enter the coordinated development of various transportation modes, capacity expansion and quality improvement. A new stage of development for the comprehensive construction of a modern comprehensive transportation system. However, there is still a considerable gap in terms of adapting to the requirements of economic development, promoting social progress and improving people's quality of life. [0003] At present, social and economic development has put forward new requirements for the construction and management of service areas. First, the fo...

The shortcoming of this model is that it does not consider the flow and direction of passenger flow from the entire network system, resulting in a lack of overall consideration in the location selection of the hub

The basis of this model is: in the process of communicating between each point (or OD pair), the node that has been passed the most times has good road conditions and traffic conditions, and is located on the shortest path of traffic between multiple pairs of nodes. However, this type of model tends to pursue the shortest path too much when calculating the shortest path, ignoring some functional applications, and there is also a certain distortion
