Principles of sustainable development extend also to the important functions that transportation systems provide. The Akwahnee Principles, developed by the New Urbanists (When City and Country Collide), advocate the following sustainable development principles:

• All planning should be in the form of complete and integrated communities containing housing, shops, workplaces, schools, parks, and civic facilities essential to the daily life of the community
• Community size should be designed so that housing, jobs, daily needs, and other activities are within easy walking distance of each other
• As many activities as possible should be located within easy walking distance of transit stops
• A community should contain a diversity of housing types to enable citizens from a wide range of economic levels and age groups to live within its boundaries
• The location and character of the community should be consistent with a larger transit network
• Streets, pedestrian paths, and bike paths should contribute to a system of fully connected, interesting routes to all destinations. Their design should encourage pedestrian and bicycle use by being small and spatially defined by buildings, trees, and lighting, and by discouraging high-speed traffic
• The community design should help conserve resources and minimize waste

WWU’s strategy for sustainable transportation planning is based on maintaining a central pedestrian corridor connecting all campus activities, encouraging safe and efficient bike access not in conflict with pedestrian uses, encouraging the use of public transit access to the university campus, and concentrating private vehicle parking on the periphery of the campus in high density structures to more efficiently use limited land areas for people-oriented uses.
