Park and Ride
Loads of cities do this, with some success. I think there are about 6 of these dotted around York, and they get quite a lot of use. It's relatively cheap for a bus ticket, buses are frequent, and avoids having to take your car round car-unfriendy medieval streets and council parking at £2.00 an hour. There are still traffic problems and lots of congestion, but the city would grind to a standstill without Park and Ride.
