Abstract:Throughout the United States, transportation agencies have begun implementing advanced parking information systems to increase customer satisfaction and to improve traffic operations. Through the use of variable message signs, these systems provide motorists with real-time information about parking availability at appropriate decision points on their route so that they can make an informed decision about where to park. These systems are being deployed in a variety of environments including central business districts, airports, and transit park-and-ride lots. The goals in deploying such a system can vary depending on the operating environment. When deployed in a transit environment, goals can include improved user satisfaction, increased parking utilization at a lot that is currently under-utilized, and increased transit ridership. This report presents the results of an independent national evaluation of two transit applications of parking management systems: one that was deployed in conjunction with two Metra Stations in suburbs southwest of Chicago, Illinois and the other which was deployed in conjunction with two Metro Stations in Montgomery County, Maryland. The study documents quantified system impacts in terms of parking utilization, transit ridership and mode choice, traffic circulation within and between transit park and ride lots, and customer satisfaction. It also includes an institutional issues review that includes organizational and institutional challenges encountered by the project stakeholders throughout the course of deployment and operation of these systems. The evaluation involved conducting passenger intercept surveys of transit riders, gathering data on transit ridership, gathering archived system data that documents in and out counts at the lots, as well as conducting a series of interviews with the staff. The results of the study indicate that it is unclear whether the parking management systems increased parking utilization or transit ridership, or whether they reduced circulation within and between park-and-ride lots. The results do indicate that commuters are in general satisfied with the sign locations and accuracy (and that they would like to see similar signs at other locations). In terms of mode share, although not many, a few respondents did indicate that the signs have affected how often they take transit and that he parking availability information has caused them to take transit rather than driving. Finally, the results show that, depending on the circumstances, parking management systems can increase driver awareness of parking alternatives or reduce circulation within and between lots.
