Streetfilms: Behind the Scenes at LA Traffic Control

I have to admit: The thought of filming a control room designed to move vehicles more efficiently didn’t excite me at
first. But once I met Senior Transportation Engineer Bill Shao and the
friendly staff at Los Angeles’ Automated Traffic Surveillance and Control (ATSAC), I was full of curiosity.

Developed to help direct traffic during the 1984 Olympics, ATSAC has grown to monitor and control over 3,000 of
L.A.’s 4,100 signalized intersections, some of them incredibly complex.
ATSAC is one of the only such systems in the country that is publicly
owned, and the technology is so advanced that even on its busiest days the control
room only requires a few people to run it.

I’m told there are regular group tours of the facility. Next time you visit LA I recommend checking it out.

    I believe the system currently covers Third Street, the Embarcadero and several intersections in SOMA, with the eventual goal of covering all signalized intersections in the city. There is also talk of combining it with Muni Central Control, which would make sense, budget permitting.

    Among other benefits, the technology allows a traffic signal to detect an LRV several intersections away, and accordingly adjust the signal timing so that the signal is green when the LRV arrives (in theory).

Oakland Unnecessarily Pits Safe Bicycling vs. Transit on Telegraph Avenue

|
At two workshops last week in Oakland, attendees overwhelmingly called for a bolder plan to make Telegraph Avenue safer and include protected bike lanes. Oakland planners ditched their original proposals for parking-protected bike lanes, instead proposing buffered, unprotected bike lanes on most of the street. In Temescal, the street’s most dangerous and motor traffic-heavy section, planners insist […]
