Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

Provides insights on historical and current issues in transportation planning. The first section describes the last five decades of planning efforts, funding initiatives and the increasing use of the roadway system. The second section is a series of fact sheets and maps of each subregion that presents the extent of the roadways, traffic volumes on major streets, transit and bicycle facility availability, future planned improvements, issues within the subregion, an overlay of the draft biological reserve, and in the northwest, a further overlay of pygmy-owl habitat with a detailed analysis of bond projects.

Provides background information relevant to the Circulation Element of the draft Comprehensive Land Use Plan. It describes historic traffic volumes for roads within the various subregional planning areas of Pima County, and compare Pima County trends to national data in areas such as vehicle ownership, travel time, vehicle miles traveled, work trip modes of travel, registration, and vehicle costs.

In order to work effectively, concurrency requirements and level of service standards mus be an integral part of long term planning and the development review process. To create incentives for density, affordable housing, and mixed use development, staff will propose the application of lower level of service standards for land use types appropriate to certain growth areas.
