The Four Pillars of Sustainable Urban Transportation

Abstract

The unsustainable nature of current urban transportation and land use is well recognized. What is less clear is the prescription for how to move towards a more sustainable future, especially given the many interest groups involved, the complexity of urban systems and the fragmented nature of decision‐making in most urban regions. It is argued that the process of achieving more sustainable transportation requires suitable establishment of four pillars: effective governance of land use and transportation; fair, efficient, stable funding; strategic infrastructure investments; and attention to neighbourhood design. A review of each pillar identifies key issues. The characteristics of an ideal body for governance of land use and transportation are considered. Trade‐offs are identified with: spatial representation; organizational structure; democracy; and market philosophy. Effective financing and pricing of urban transportation may be distorted because responsibility for infrastructure is separated from service provision. Financing mechanisms are categorized depending on vehicle use and location. Investment in infrastructure for alternative fuel vehicles and intermediate semi‐rapid transit may be required in many cities. Major investment in public transit infrastructure will likely not suffice if macro land use and micro neighbourhood designs are not supportive of these investments.
