Parking information - aggregating it and figuring out how to use it is a hot topic that can be used to help people drive smarter.

One example of a City that is embracing smart parking is Walnut Creek. They recently released an RFP that offers details about what they are looking for in their smart parking program as well as a potential architecture around it. More info is available here -

San Francisco, San Jose, Berkeley, and others also have similar projects going which are at various stages of development.
