LADOT Celebrates The Expansion Of ATSAC Center

LADOT Celebrates Launch of $60 Million South LA EcoLab

Today LADOT joined Mayor Eric Garcetti and representatives of the LA28 Olympic and Paralympic Games for the ribbon cutting and celebration of the expansion of the LADOT ATSAC (Advanced Transportation Systems and Coordination) Center! ATSAC allows LADOT to manage traffic control systems citywide to improve the efficiency of travel. ATSAC was initially established in 1984 to prepare the city for the '84 Olympics. 

When the original ATSAC facility was established in 1984, the system managed 118 signals. Today, the system manages 4850 traffic signals and is capable of providing prioritization for buses, rail, and pedestrians as well as manage bike signals throughout the city. Additional functions include adaptive traffic signal control to react to changing traffic conditions as well as real time data on congestion and signal malfunction. The new location allows more space for a larger team of specialists to collaborate on these efforts as well as prepare the city to host major events  such as the upcoming 2026 World Cup and 2028 Olympics. .

Some of the advantages of the new headquarters include: 

  • Multiple independent control stations for traffic engineers, traffic officers, transit operators, fire, and police to share the same room and better coordinate their activities during emergencies or special events;
  • An advanced video wall display system to better capture, display, and share information; 
  • Greater capacity for teams to work on site and from remote locations by decoupling the hardware from the workspace so that staff can access the operations even if not able to access the control room during an emergency

This new center will ensure LADOT and Los Angeles remain a technology leader for the next generation and ensure we can manage both large events and improve the every day travel experience of residents whether they move about our city by transit, foot, car, or bike.
