Abstract: A method for determining traffic in a geographic area is shown. The method includes generating parking reservation data corresponding to a plurality of peer-to-peer parking reservations, each of the peer-to-peer parking reservations comprising a reservation by a user of the traffic management system of a parking spot offered by another user of the traffic management system. The method further includes determining a subset of the peer-to-peer parking reservations associated with the geographic area. The method further includes generating an indication of the traffic in the geographic area using the parking reservation data for the subset of the peer-to-peer parking reservations associated with the geographic area.
