Aggregated Surveillance Camera Resources
This resource from Carnegie Mellon could prove useful with traffic information, weather, and other day-to-day info for commuters:
The Camera Watch project is part of our Surveillance of Surveillances ( SOS) effort. We are constructing a repository of links to publicly available on-line webcams, where the webcams of interest are those that observe the public in public spaces. At present, we estimate there are about 10,000 such cameras displaying public places in the United States. Our goals are to assess the number and nature of such cameras, explore potential uses, and analyze and propose related policies and best practices.
Additionally, Gerrit Visser at SmartMobs points to half a dozen traffic information and camera resources.
