Enhancing Resource Sustainability by Transforming Urban and Suburban Transportation


Urban regions worldwide are dominated by the need to provide for large numbers of high-speed, high-mass vehicles. Current strategies result in congestion, social fragmentation, and environmental degradation. An alternative urban design is presented that incorporates two separate road systems: one for light, low-speed vehicles and another for heavy, high-speed vehicles. This design enhances travel efficiency and sense of community, while minimizing energy use, water pollution, and nonrenewable resource consumption.
