Spatial development and the sustainability of urban areas: Proceedings of the 14th Hong Kong Society for Transport Studies (HKSTS) International Conference on Transportation and Geography

This paper explores the potential impact of alternative spatial development strategies on the sustainability of urban areas. A Land-Use and Transport Interaction model (TAMMS) is used to generate data regarding the performances of three specific development strategies for Tyne and Wear, UK which are then measured against the baseline of a ‘Trend’ option. The area’s changing industrial and population base over recent decades has affected demands for dwelling space and mobility causing pressures to develop particularly in outer urban areas. The spatial development strategies tested are a ‘Compact City’, ‘Market-led dispersal’ and ‘Planned urban expansion’. Performance is tested against key sustainability indicators covering transport and travel, the environment, society, economic performance, land requirements and energy use. Results indicate that the strategies would have limited impact on the long-term sustainability of the area. Instead, it is suggested that technology-driven solutions in key sectors are more likely to have a bigger impact.
