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 multi-scale simulation method for land use and traffic, which belongs to the technical field of urban planning. This method is based on land use and traffic integration theory, system dynamics model theory, irregular cellular automata model theory and scenario planning theory, combines macro model and micro model, and uses urban socioeconomic data to simulate Urban land evolution and transportation system evolution. The present invention uses the aggregation results generated by the macro model in the distribution of the micro model, and constructs a model that combines both the system angle and the individual angle, and the macro and micro characteristics, which is more in line with the general development law of the city and the people-oriented urban planning idea. Combining the irregular cellular automaton model of the frontier research in the urban model neighborhood with the traditional four-stage traffic model, constructing a microscopic land use and traffic integration model based on specific evolution rules, and more targeted planning for different scenarios Analyze and forecast.

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...
