City impedance calculation method based on points of interest

Abstract

The invention relates to a city impedance calculation method based on points of interest, comprising the following steps: (1) acquiring data of points of interest in a city from an Internet medium, including the name, type, latitude and longitude positions and operation time data of each point of interest; (2) sorting the operation time data of the points of interest, and outputting a standard format; (3) using city road network data to mark out plot units and determine the center of each plot with a polygon completely closed by a road system in the city as the basis, and mapping the points of interest to the corresponding plot units based on the latitude and longitude positions; (4) planning the routes from the center of each plot to all the points of interest within the reachable range, and obtaining route parameters; and (5) calculating the impedance value corresponding to each plot unit in the city according to the route planning result by considering the route parameters and population parameters in the corresponding plot unit. The method is beneficial to quantifying the impedance values of different plots of a city in different periods of time, thus providing reference for traffic management and urban land use planning.

Description

technical field [0001] The invention relates to the technical field of smart city planning, in particular to a method for calculating urban impedance based on points of interest, which provides reference for urban traffic management and plot planning. Background technique [0002] For the calculation of urban travel impedance, domestic and foreign scholars have carried out corresponding research on this in recent years, and put forward some calculation methods. Among them, the utility model based on the discrete choice model sets a utility value with the population or density as a parameter for each end point in the region, and the individual will choose the point with the highest utility as the travel choice to judge the size of the impedance, but ignores the Complex urban road conditions make the accuracy of the method not high. The traditional BPR speed-flow model obtained through regression analysis and its improved method, although the road impedance function of factor...
