Sustainable Transportation


The Problem: Unsustainable Transportation

Urban areas are facing significant transportation challenges that can make or break their economic, social and environmental futures. These include:

  • Rising traffic congestion and decreasing productivity as more vehicles drive more miles each year, while also increasing dependence on petroleum.

  • Worsening local air pollution and a substantial contribution to global warming. The U.S. emits 25% of total global greenhouse gas emissions, one-third of which come from the transportation sector.

  • A declining sense of the quality of life in urban areas in the face of congestion, increasing road safety concerns, and growing noise and air pollution.

  • Decreasing access by the poor to transport options as public transit declines in favor of private vehicles
The Solution: Smart Transportation

A few but growing number of cities are now adopting sustainable transportation strategies which demonstrate that a transportation system can be designed, managed, financed, and operated in a manner that reduces transportation demand growth and fixes these problems. These strategies enhance economic development, improve the quality of life, and reduce congestion, local air pollution, and global warming.

They....
  • Integrate land-use and transportation decisions through Smart Growth initiatives.

  • Provide well-funded transportation alternatives such as public transportation, walking, and biking.

  • Promote multiple occupancy vehicle use.

  • Eliminate the need for travel through telecommuting and electronic commerce.

  • Improve vehicle design and use clean alternative fuels.
