Green Corridors

This chapter describes how greenways can be a constituent of sustainable urban mobility (SUM) systems that reduce automobile dependence while simultaneously having positive environmental and social co-benefits. It begins by providing a brief background on the harmful effects of automobile dependency. A chronological review of the evolution of greenways as a typology, divided into five generations starting from pre-1900 until today, demonstrates how various economic, political, environmental, and social factors have shaped blue-green corridors in different cities, mainly in English-speaking countries. The discussion then focuses on the integration process between greenways and SUM planning, as well as highlighting some of the planning challenges and opportunities of (re)developing greenways to support as non-motorized transport corridors. By critically analyzing the evolution of greenways in relation to urban mobility and their integration process, this chapter supports green space, transport, and design professionals to work toward a shared vision of sustainable cities.

AbstractAs the transport challenges facing urban areas intensify, innovative solutions are required to address the social, economic and environmental impacts arising from overreliance on private motor vehicles. Velomobiles offer a range of advantages but do not feature on the radar screen of urban transport policy makers. This chapter explores the challenges and opportunities of increased adoption of velomobiles as an urban mobility option. A scan of existing velomobiles is used to define typical characteristics of these vehicles and place them into perspective against relevant travel options before they are assessed in the context of typical vehicle regulations and facility design guidelines. The opportunities and challenges associated with greater adoption of velomobiles in the context of urban travel are examined through the lenses of technology adoption and the sociotechnical framing of independent travel options. Shared mobility is identified as one potential way of broadening the base for velomobile adoption in urban areas.
