How does parking interplay with the built environment and affect automobile commuting in high-density cities? A case study in China

Abstract

This study investigates an important but often overlooked problem – the interaction between parking and land use – to examine the effects of the built environment on car commuting. Using the case of Shenzhen, China, a structural equation model is employed to examine the tripartite relationship among the built environment, parking supply and car commuting. The parking–built environment relationship partly reflects the parking supply mechanism that is collectively influenced by the parking market and regulations. The results indicate that, because of the high cost of constructing parking, property developers are reluctant to build sufficient parking spaces for the residential population in densely built neighbourhoods with small lot sizes. However, minimum parking standards often lead to more parking provisions in dense central locations. Therefore, the benefits of compact land use and transit-oriented development (TOD) for reducing car use are either reinforced or offset depending on the various interrelationships between parking and the built environment. In the context of policy implications, a fine-grained urban fabric should be particularly supported, considering its significant effects in reducing car commuting, as well as its potential role in fostering a well-functioning parking market.
