There are several notable examples of successful ridesharing in the United States. There is, however, currently no general body of evidence that can be used by employers, government officials, and developers to predict the percentage reductions in both long-term parking demand and in employee automobile trips that can be achieved at a specific employment site as a result of establishing an organized ridesharing program. To gather information about the effects of a ridesharing program, Seattle/King County Commuter Pool initiated a parking use study in the winter of 1983 that involved 14 office sites in suburban King County. Suburban sites were selected because they tend to minimize the number of extraneous variables that can complicate a parking use analysis. The 14 sites selected were similar in terms of (a) surrounding land use, (b) employee density, (c) employee activity, (d) site configuration, and (e) level of available transit service. The only notable difference among the sites was that 7 of the 14 operated organized ridesharing programs for their site employees. Average parking use rates for these two groups were compared to determine if a measurable difference in parking demand, which was due solely to the presence of the organized ridesharing programs, could be detected. The study's objectives, research methodology, and basic findings are discussed and some key factors that emerged in association with the ridesharing programs and the different levels of parking demand are analyzed.
