Transportation: Sustainability Principles
Transportation represents the second largest (19%) household expenditure in the United States, after housing. Since WWII, the automobile has been the preferred mode of transportation, both by individual choice and public investment. However, increasing gasoline prices and a greater awareness of the environmental cost of cars are shifting public perceptions and priorities. Cities increasingly understand that they can benefit from more sustainable transportation options -- in lower parking congestion, improved air quality and increased disposable income available to their citizens. The bottom line: cities and their residents want and need a broader range of transportation options, both for financial and environmental reasons.
Prioritize Transportation Modes
Promote walking first, cycling second, public transit third, multi-passenger/shared vehicles fourth and single-passenger vehicles last.
Advocate Alternative Forms of Transportation
Cars are major contributors to air pollution, traffic congestion, fuel consumption, and health problems. Promote alternative modes of transportation through public service campaigns, incentives, and other programs.
Integrate Transportation Modes
An environmentally sustainable transportation network is maximally successful when it is coordinated to produce a seamless system among all transportation modes. Individuals should be able to transfer easily and conveniently between sub-networks (pedestrian walkways, bicycle routes, public transit, multi- and single-passenger vehicles).
Ensure Accessibility for All
Always consider a community's diversity of needs when planning or improving a city's transportation system. For example, provide options for people with limited incomes, people with disabilities, the elderly, and parents with baby strollers.
