Costs and Effectiveness of Lower-Speed, Environmentally-Friendly Urban Highway Designs

项目名称：	Costs and Effectiveness of Lower-Speed, Environmentally-Friendly Urban Highway Designs
摘要：	Adding capacity to ameliorate urban road congestion is often thought to be infeasible due to its great expense. This proposal seeks to investigate differentiated design standards as a source of capacity additions that are more affordable and have smaller "footprints," thus smaller aesthetic and environmental impacts. The research will examine the tradeoff between providing capacity for high-speed off-peak travel, when peak travel is severely congested, versus providing more capacity but only for moderate-speed travel. It will also examine the potential savings in cost and footprint from designing certain roads to be for passenger vehicles only. Thus, the research will show under what conditions lower-speed, environmentally-friendly highway designs are cost-effective. The results will provide guidance for metropolitan transportation planning, in particular guidance concerning the emphasis given to different types of highways for handling anticipated traffic growth.
