"The three modified Caltrans applications providing highway traffic information for the public were made available on the California portal. One site provides access to live video of traffic. The user selects the metropolitan area and the camera location to see realtime traffic at a particular point along the freeway. Another application, the Realtime Freeway Speed Map, displays current freeway traffic speeds in selected areas. The Photolog allows users to select a section of highway and take a virtual tour along that route."
