The Metropolitan Transportation Commission in the San Francisco Bay Area embeds FasTrak toll transponders on area highways to determine traffic conditions in real time. These transponders are in place even outside of toll bridges for the purpose of measuring traffic flow. You can see these traffic conditions at 511.org.
