Embodiment Construction

[0045] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0046] The present invention aims to provide a multi-scale model of land use and traffic to simulate changes in urban land and traffic, such as urban land evolution, traffic accessibility, road congestion, and the like.

[0047] The invention is based on the theory of land use and traffic integration, system dynamics model theory, cellular automata model theory and scenario planning theory.

[0048] Step 1: Program setting. Firstly, the key variables are determined, which requires the analysis of three issues: 1. The scale of urban space expansion during the planning period (urban land demand); 2. The spatial form of urban land during the planning period (urban land allocation); 3. Planning During the period, urban traffic is in harmony with urban space. Determine the content of different simulation scenarios based on key va...

Abstract

The invention provides a method oriented to land utilization and traffic multi-scale simulation, and belongs to the technical field of urban planning. The method is characterized in that a macroscopic model is combined with a microscopic model on the basis of a land utilization and traffic integration theory, a system dynamics model theory, an irregular cellular automata model theory and a scenario planning theory, and urban social economic data is adopted, so that urban land evolution and traffic system evolution can be simulated. An aggregation result generated by the macroscopic model is applied to the allocation of the microscopic model in order to construct a model which has a system aspect, an individual aspect and macroscopic and microscopic features and is more accordant with the urban general development law and the people-oriented urban planning thought. A frontier research irregular cellular automata model in the neighborhood of an urban model is combined with a conventional traffic four-phase model in order to construct a microscopic land utilization and traffic integration model based on a specific evolution rule, so that different scenario planning can be analyzed and predicted more specifically.

Description

technical field [0001] The invention belongs to the technical field of urban planning and relates to an integrated planning method for urban land use and traffic. Background technique [0002] (1) Introduction to the model [0003] The research on urban land use and transportation integration model has a long history. Since the mid-1950s, some scholars have begun to conduct theoretical research on land models based on the analysis of location characteristics, including the Central Place Theory and the Sector Model proposed by the Chicago School. With the emergence and popularization of computer technology, the theoretical model of land use and transportation integration began to enter the planning practice level, and a large number of integrated models emerged. According to the principles on which the models are based, these models can be divided into the following three types: ①land use and traffic models based on spatial interaction / gravity models; ②models based on econo...
