"The information on the signs comes from 15,000 sensors Caltrans has placed on freeways to measure traffic speed. The fiber optic system has a sensor every half mile of urban freeway, transmitting information every 30 seconds. Officials pick key commute markers and calculate the commute time given the traffic flow. Each sign contains commute times for two destinations."

"It won't ease congestion, but officials are hoping it will ease congestion anxiety."
