ABSTRACT

This chapter discusses time-geography and its role in facilitating sustainable mobility. It highlights two research projects that use time-geographic techniques and perspectives to answer research questions surrounding more sustainable forms of travel. The chapter discusses the concept of sustainable mobility, and contrasts conventional transportation planning with sustainable mobility planning. It also discusses the Green Accessibility project addressing the expected emissions associated with space-time and network-time prisms. The chapter describes the Moving Across Places Study (MAPS) project addressing active transportation. Mobility researchers and planners use the space-time prism and the network-time prism (NTP) to delineate individuals' accessibility considering scheduling constraints and the ability of the given environment to afford the trading of time for moving in space. NTPs model accessibility for the case where individuals' movements are confined by spatial networks like streets, highways, biking lanes and pavements. The chapter concludes with some summary comments and research frontiers.
