Many states, regions, localities and private entities promote the use of alternative modes, alternatives to signal occupant automobile travel, for a variety of reasons. Of interest to this research, many regions and states use the promotion of alternative modes as an air quality strategy. A reduction in the amount and timing of automobile travel is often one element of a region's air quality strategy. In Arizona, the two largest urban areas, Maricopa and Pima Counties, each have travel or trip reduction programs, aimed at reducing automobile emissions by shifting commuters to alternative modes. The Arizona Department of Transportation (ADOT) commissioned this research to assess current experience with the use of alternative modes as an air quality mitigation strategy. This includes investigating what other state departments of transportation (DOTs) are doing to promote, support, and evaluate alternative modes. It is hoped that the information provided here will assist Arizona planners and program managers to inform state policy and provide the perspective and insights necessary for ADOT personnel to effectively communicate with their counterparts at the state's regional and local agencies and state air quality planners. |
