Old news... (Score 1)

San Antonio and Detroit were the first two cities in the US to install this type of system. Both of these cities now have extensive networks of sensors on their highways, although I think that San Antonio is much further along in the project. (Launched first in the country.)

There is real-time web traffic data, and signs/cameras/sensors all over the cities huge network of highways, and many major streets, as well. Great idea, but old news, even in the US...
