In this Friday, Oct. 18, 2013 photo, cars pass over Caltrans traffic sensors on the State Route 134 Freeway State Route 2 Freeway workers monitor traffic on Southern California freeways on a large electronic display and small computer screens at the Los Angeles Regional Transportation Management Center in Los Angeles. About one-third of traffic sensors that Caltrans operates on highways statewide do not work. There are various reasons for this, including equipment failure, copper wire theft and construction projects that sever the systems locally. (AP Photo/Reed Saxon)
