Embodiment Construction

[0048] widely used in traffic research as Figure 4 The Nguyen-Dupuis network shown to test various methods. Table 1 lists road parameters such as free flow travel time and road capacity in this network.

[0049] Table 1 Road parameters of Nguyen-Dupuis test network

[0050]

[0051]

[0052] There are two origins 1 and 4 and two destinations 2 and 3 in the Nguyen-Dupuis network. Assume that the employment increase target for 2018 is 100,000, that is, D=100,000, which is stipulated or predicted by policy makers. The problem is to determine the best optimal commercial land layout pattern for Destinations 2 and 3 in order to take full advantage of the transportation system. A number of N=500 layout patterns are randomly generated by the Dichiclet distribution Dir(α), where α is a vector (1,1). The present invention calculates traffic system performance for each allocation mode. For business centers 2 and 3, the existing employment target attractiveness is 500,000 and ...

Abstract

In order to make urban wisdom grow, policymakers often face a challenging problem, that is, how to carry out the commercial land layout based on the performance of the transportation system, so as tocoordinate the development of transportation and land use. The invention provides a novel two-layer model system to solve the problem, wherein, the upper layer model optimizes the performance of the traffic system through the layout of the commercial land, and the lower layer realizes the traffic system equilibrium through the sequential model with feedback, wherein the upper layer model optimizesthe performance of the traffic system through the layout of the commercial land. In addition, the polynomial logit model is applied to the traffic distribution to fully represent the traveler's decision-making behavior. In order to solve the proposed two-layer model, the present invention is based on Dirichlet distribution, iterative weighting method (MSA), Frank-Wolfe algorithm and Dijkstra algorithm, an efficient Dirichlet assignment algorithm is designed. Finally, Nguyen-Dupuis network is used to validate the feasibility and effectiveness of the proposed method and algorithm. The modelingmethod can be used as a valuable tool to determine the layout of urban commercial land.

Description

Technical field: [0001] The invention establishes a commercial land layout optimization method based on traffic system performance, and belongs to the technical field of traffic planning. Background technique: [0002] Transportation Oriented Development (TOD) is an urban development strategy that optimizes the performance of transportation systems while meeting urban development goals. Therefore, policy makers often face a challenging problem, that is, how to make land use layout based on the performance of the transportation system, so as to coordinate the development of transportation and land use. In fact, the location, scale, and intensity of land development are determined by policy makers (usually the government), while the generation, destination, means of transport, and routes of traffic trips are determined by travelers. The levels are not the same. The government designs land use and transportation policies, while travelers decide their own travel behavior on a ...
