Integrated land-use and transport planning for future cities: and the importance of active transport
Land-use-transport integration (LUTI) is concerned with the development, management and operation of urban transport systems that provide for sustainable outcomes for our cities. LUTI is primarily concerned with the optimal distribution of facilities and services in an urban area so that these are available to all of its inhabitants in ways that minimise adverse environmental impacts, whilst maximising opportunities for sustainable economic development and social interaction. LUTI is a key consideration in low carbon mobility. A major means for achieving this is through the encouragement and use of the active transport modes walking and cycling and public transport, because access to public transport generally requires substantial use of the pedestrian and cycle modes. The key concept behind LUTI is in fact the basic driver of urban development: accessibility. In the planning context, accessibility is about the effort required for people and enterprises to engage in everyday life. Integrated planning of transport and land use can offer high levels of accessibility based on the use of active transport. Amongst the many issues facing planners are environmental impacts, both local (e.g. noise and air quality) and global (climate change and greenhouse gas emissions), economic productivity, conservation of resources (especially the use of land), traffic congestion, social severance and public health. Following the established principles and practices of LUTI - while these may not always coincide with what has been past practices in our cities - offers a systematic path to long-term resolution of these issues. This chapter will explain why and how this can be accomplished.
