Emerging Techniques for Urban Transportation Planning

摘要

Despite several decades of intense effort, urban transportation planning is in its infancy of development and refinement, as evi-denced by the fast pace of new techniques and methodologies being proposed and developed. In this series of two special issues on urban transportation planning, the first issue [Journal of Urban Planning and Development, 128(4), 2002] focused on reviews of recent methodological advances. This second issue covers emerging techniques that extend the boundries beyond the traditional four-step planning methodology. Some of these techniques are drawn from other fields of studies. Others introduce new dimensions to reconsider the problem. All in all, these approaches open up new possibilities and dimensions as well as make planning procedures more robust, thereby enabling the planning results to be applicable to a wider range of scenarios and for the longer-term future.
