Parking is costly and limited in almost every major city in the U.S., contributing to increased congestion, air pollution, driver frustration, and safety problems. Furthermore, limited parking can also constrain transit ridership in dense regions, such as the Bay Area, where transit parking is full or close to capacity at 26 of BART's 29 transit stations. Job growth is projected to increase by 25% by 2010 in the Bay Area; thus, greater parking shortfalls are expected at transit facilities and in dense urban areas. With parking construction and land use costs increasing, innovative alternatives for meeting near-term parking demand are needed. With powerful innovations in wireless Internet technology and enhanced transit data systems, service oriented smart parking management approaches such as "dynamic space sharing" are on the verge of providing a cost-effective solution. The concept we call "dynamic space sharing" can be employed to increase available parking inventory (without building additional facilities) and improve the driver experience through the use of wireless communication and matching logic technologies that increase parking capacity by managing privately-owned or previously restricted spaces. These spaces, such as private parking (e.g., corporate, apartment, hotels), private driveways, driveway curb space, loading zones, access alleys, could be made available for public parking utilizing dynamic management technology that accounts for the specific needs of the rights' holders. When valuable space is made available to the public, the rights' holders share in revenue generated from the space provided. Preliminary estimates suggest that space sharing can increase available parking inventory by 15-40% in many areas (Victoria Transport Policy Institute, 2001). Because space sharing is highly desirable for both the public and the rights' holders, it is expected to generate significant revenue. By employing sophisticated database technology, pricing can be adjusted dynamically (e.g., value pricing based on time of day) to foster localized behavior shifts.
