The Influence of Built-Environment Factors on Connectivity of Road Networks in Residential Areas: A Study Based on 204 Samples in Nanjing, China

Over the past decades, China has built a large number of superblocks and gated residential areas, which have contributed to increased congestion on urban road traffic. Although some studies found correlation between environments travel convenience, there is little quantitative evidence explain factors influence connectivity networks. This paper aims clarify indicators in Chinese areas that affect accessibility their proportions through more method provide basis for planning design decisions. To this end, study took 204 three districts Nanjing, as sample calculated 16 built-environment indicators. The path distance (D) pedestrian route directness (PRD) from center these nearest intersection were measured by GIS outcome variables. First, analysis was used screen significant variables, multiple linear regression models examine influencing D PRD. Then, binary logistic performed model could determine whether environment area met requirements convenient travel. results revealed length long side, size, total significantly related D, entrances exits, density, X ratio positively correlated with network complexity, boundary shape according degree correlation. Meanwhile, other such density negatively D.
