Abstract: Disclosed is a system that facilitates finding on-street parking. A community of users has an application on their mobile communications devices that allows them to inform each other when vacating on-street parking spaces. When a user operates his automobile to vacate an on-street parking space, a message is transmitted wirelessly that indicates the position of the parking space. Another user in the community who is driving around looking for a parking space can specify a desired area. The availability of the parking space vacated by the one user is matched with the desired area of the other user. A message indicating the available parking space in the desired area is transmitted to the other user for display on the wireless communications device of the other user.
