Title: Full Cost Analysis of Accessibility

Abstract: Accessibility measures the ease of reaching valuable destinations. For transport systems, accessibility combines travel costs and opportunities into a single metric, which represents both the transport network and land-use. Traditional accessibility metrics have been analyzed from the perspective of travel time – considering the time cost of travel. This fails to fully capture the full travel costs, especially the external costs of travel. In this presentation, a framework of extending accessibility analysis is proposed combining the significant cost components of travel, time, safety, emission and money, with accessibility analysis. By examining both private costs, which individual travelers consider when making travel decisions, and external costs, which society should consider when making investment decision, this approach better aligns accessibility with the goals of evaluation for transportation planning. A proof-of-concept analysis based on a toy network was conducted to prove the practicability of the framework. The current studies focus on the implementation of the framework on Minneapolis-St.Paul metropolitan region.
