Method for evaluating influence of built environment on traffic operation condition

Abstract

The invention discloses a method for evaluating the influence of the built environment of an urban hot spot area on the traffic operation condition, and the method comprises the specific steps: collecting the multi-source data of POI, road networks, public transport stations and the like, and carrying out the cleaning processing of the data; based on the POI data, using a kernel density estimation algorithm to extract a city hot spot area; establishing a hot spot area buffer influence area, and measuring and calculating POI data density, a land utilization entropy index, a road network density and a public transport accessibility index in the area to establish environmental element indexes; acquiring the road congestion proportion of the hot spot area, and obtaining a traffic operation index through conversion, thereby describing the traffic operation condition of the hot spot area; and establishing an evaluation model of the influence of the built environment on the traffic operation condition, and quantitatively evaluating the influence of the built environment of the hot spot region on the traffic operation condition. The method can guide reconstruction and remodeling of the construction environment of the hot spot area, optimizes the traffic operation condition of the hot spot area, and provides a theoretical basis for urban traffic resource allocation reconstruction and new planning construction.

Description

technical field [0001] The invention relates to an evaluation method for the impact of built environment in urban hotspot areas on traffic operation status, and belongs to the field of urban land use and traffic impact evaluation. Background technique [0002] The agglomeration effect of big cities has gradually increased the density of urban land development, especially in the hotspot areas with large traffic flow and high commercial density within the radiation influence range of rail transit stations, which have caused a huge impact on urban traffic operations. Built environment factors such as land development and utilization, block design, and accessibility of public transportation facilities are closely related. Optimizing traffic operation conditions in hotspot areas is an important way to solve the bottleneck of rail transit travel services and improve the efficiency of commuting throughout the process. Research on the built environment of urban hotspot areas It has ...
