Trips123 provides traffic and transit conditions for New York City and the surrounding area. It formally launched April 6, five years behind schedule, and has cost $20 million, half of which came from a federal grant. The New York Times has the details behind the delay (free registration required). Design-wise, and in terms of the maps, it does look a bit dated, even crude; I imagine that it would have been much more spectacular in 1999. Via Urban Cartography.
