This fall, San Francisco will test 6,000 of its 24,000 metered parking spaces in the nationís most ambitious trial of a wireless sensor network that will announce which of the spaces are free at any moment.
Drivers will be alerted to empty parking places either by displays on street signs, or by looking at maps on screens of their smartphones. They may even be able to pay for parking by cellphone, and add to the parking meter from their phones without returning to the car.
Although this sounds cool, can you imagine 20 drivers getting the same message on their cell phone and rushing to one open parking space! Hey maybe this is next "spectator amusement" sport ...:)

It needs a queuing system so that when you get within a mile or so of your destination you push a button and it sends a signal to the one or two PDAs that are closest to the available parking spot that have requested a spot.
Or maybe you put the address in your GPS, push "parking" and then alerts you to an available spot when you get within .5 miles of your destination but it would still need some kind of a queuing system.
It is being "studied" in Philly as well.
