The relationship between Angelenos and traffic is a dysfunctional one. In a city without much weather, we obsess, instead, over traffic.
So a trip to ATSAC is sort of a traffic pilgrimage. ATSAC is the Automated Traffic Surveillance and Control center located under City Hall East, downtown. The computerized system monitors and controls every traffic light in the city, making real-time adjustments based on traffic conditions at about 4400 intersections. ATSAC was first used to route vehicles around the Coliseum during the 1984 Olympics; now it’s one of the largest and most sophisticated traffic control systems in the world.
Brian Taylor, director of UCLA’s Institute for Transportation Studies, says ATSAC has increased the efficiency of traffic flow but is fighting a losing battle against the city’s high population density and limited road capacity.
Los Angeles ranks second among major American cities in the number of residents per mile of roadway. (Honolulu is #1.) Projects that might significantly ease congestion in the long term, like double-decker freeways or rationed access to roads and parking, are either too expensive or politically unpalatable.
