Opening up the corridor planning process makes a difference. The holistic transportation perspective can lead to environmental integration. Local transportation funding makes a big difference. The Suburban Sprawl Future Metropolitan sprawl rules. Densities required for TODs are controversial.
Planners assume densification can occur in increments.
Transportation projections favor roads. In the absence of real models, TODs are often feared and misconstrued. While we have found few institutional models which integrate transportation and land use authority, we conclude that several approaches do exist which could be beneficially adapted, in whole or in part, by elected officials, citizen activists and transportation and planning professionals across the country. These models can be augmented by specific examples we found such as Florida's use of roadway tolls to protect adjoining sensitive environments, and San Diego's coordination and sharing of city and transit authority staffs. Further research in several areas could open new opportunities for connecting transportation and land use in positive ways including a state by state inventory of interjurisdictional enabling legislation, exploring ways to implement road pricing strategies, and developing better tools for making the transition from collaborative planning to implementation.
