Purpose of this study was to determine the best location and the optimum feasible quantity of additional parking spaces that would effectively serve potential demand for change-of-mode parking at the interface between highway and passenger rail systems. Selection criteria, such as available land, accessibility to highway system, current rail ridership, and current parking demand, were used to identify 20 potential fringe parking sites. Future demand for parking spaces at the selected sites was determined in four steps. The first step dealt with trip interchanges. All future trip makers who reside in the influence area of each of the potential sites, and whose trip destinations lie in the distribution service area of the passenger rail system were identified and quantified. In the second step, the market share of each mode was calculated by using a disutility mode-choice model. Disutility rates for the automobile and rail modes were computed for each of the trip origin areas, and the percentage of passenger rail trips was derived from diversion curves. In the third step, the proportion of projected commuter rail patrons demanding parking spaces at each site was established by using a relationship between the distances patrons travel to the station and their access modes to the station. Finally, additional parking spaces over and above the number of spaces already existing or planned were calculated for each site. /Author/
