Title:

Simulation Evaluation of External Costs in Road Transport Under the Openness of a Gated Community

Abstract:

Most residential quarters in Chinese cities are typically walled off from their surrounding roads for a purpose of making themselves secure. Recently, the Chinese government has decided to open the gated residential community thoroughly in order to improve traffic capacity and coordinate major roads in the road network, which will inevitably pose a direct impact such as environment pollution to dwellers in the community. Unfortunately, before this decision, it is less addressed whether this measure works for road traffic and how far the residence can be adversely affected. Hence, this paper proposes a comprehensive method combined by microscopic traffic simulation, Comprehensive Modal Emisssions Model (CMEM), CALINE4 and vehicle noise emission and attenuation model, as well as with a consideration of social cost, to evaluate the influence of the openness between residential quarters and surrounding roads. The hybrid model was then examined to evaluate an assumptive case of a rectangular gated community under different traffic flows and opened ways. The case study shows that the hybrid method is reasonable to be a consultation method for the road re-planning around an opened community. Appropriate extent of openness and re-planning based on actual situation is the foundation of healthy development for communities and cities. Based on the case study results, this paper supports some strategical suggestions for improving the enclosed residential areas to make their openness more friendly between traffic capacity and environmental risks.
