The Car Park API provides real time occupancy status of selected car parks. This initial release provides results for Opal Park&Ride car parks. Opal Park&Ride is a trial designed to free-up more spaces at commuter car parks for those who want to travel on public transport. The data feed contains the occupancy information by type in real time.
