Gis-based urban density on the impact of travel demand analysis

Abstract

Urban density is one of the important factors to measure the occurrence of traffic in a region. It can not only reflect the intensity of traffic demand well, but also provide a way to quantitatively analyze the influencing factors of urban traffic demand. Take Nanchang and Jiujiang, cities with different geomorphic features, for example. The spatial analysis technique of GIS is used to calculate the urban density that can reflect the density difference. According to the characteristics of urban traffic demand, urban density is divided into single density and compound density. Through spatial statistical analysis, the impacts of various urban densities on traffic occurrence, travel distance, travel time and travel mode are analyzed. The research shows that different urban density corresponds to different traffic demand characteristics; In a certain threshold range, there is an obvious monotonic relationship between urban density and traffic demand.
