Fast Company has a post up, ranking Top10 Smart Cities. Interesting list, but you should bear in mind what it is that we talk about. Boyd Cohen, the author of the study, posits:

Smart cities use information and communication technologies (ICT) to be more intelligent and efficient in the use of resources, resulting in cost and energy savings, improved service delivery and quality of life, and reduced environmental footprint–all supporting innovation and the low-carbon economy.

To translate this: Smart Cities are about managing cities.

To which I recommend you read Adam Greenfields weeknote on the Smart City Expo in Barcelona:

In fact, it’s very rapidly becoming evident to me that “the smart city” does not refer to any general conception of the circumstances arising where information technology intersects the urban environment, but is rather a very specific discourse within that larger field of inquiry. To be precise, it’s a discourse about the instrumentation and quantification of municipal processes, specifically for ease and efficiency of management. That’s fine, as far as it goes, but it’s so very partial and limited a conception of things. As we’ve pointed out many times before, it’s a point of view that virtually excludes any conception of the citizen as anything other than an object to be acted upon. It turns its back on by far the greater part of the potential bound up in these technologies.
