Carsharing is an exciting new alternative transportation mode that is gaining popularity throughout the United States. Carsharing is becoming increasingly popular because it ties directly into the transit system by providing an alternative to car ownership for trips that cannot be made easily using mass transit. Few attempts have yet been made to introduce carsharing in smaller cities; however, as carsharing continues to grow in popularity, more small cities will undoubtedly be interested in its implementation. Small cities are defined in this paper as cities with populations between 50,000 and 150,000, with a well-defined central business district and a sizeable employment base. These cities present unique situations for carsharing due to their limited transit networks, lower population densities, and varied demographics. This paper analyzes US carsharing organizations, with a focus on small city programs, and provides both the basis for an implementation framework and steps for program analysis. Various studies have been conducted on carsharing in the United States, but only a few have tried to quantify the relationship between characteristics of a city, in terms of form and function, and the size and scope of a carsharing program. Census data will be analyzed in a regression analysis in an attempt to determine relationships between the membership size of a carsharing program and the demographic, social, and economic characteristics of a city. Small city local governments, grassroots efforts, and transit agencies can use these analyses and recommendations to help guide their own implementation efforts.

Notable Practices for Incorporating Rapidly Urbanizing Rural Areas into the Metropolitan Planning Process

There is a demonstrated need to include rural areas projected to become urbanized by 2010 in the metropolitan transportation planning process. This research is to identify, through a peer research process, novel and low-cost tools and approaches for improving metropolitan transportation planning for rapidly urbanizing rural areas. Results of the 2000 Census showed a gap in the planning process for rural communities near rapidly growing urbanized areas and new urban centers. The metropolitan transportation plan (MTP) or regional transportation plan (RTP) for long-range planning should, but often does not, include areas that will be urbanized within next 20 years. Key rural stakeholders omitted from the process are unprepared for the change in status and funding eligibility for urbanized areas. This research report references examples of innovative transportation planning practices by states and metropolitan planning organizations which include rural communities near rapidly growing urbanized areas, or small towns that are expected to become urbanized by the next U. S. Census. The goal is to identify methods to strengthen the involvement and contribution of key rural stakeholders in the metropolitan planning process.
