542 Global Traffic Technologies (GTT) is to implement its Opticom traffic pre-emption solution at nine of the busiest intersections in the city of Inglewood in California.

Opticom works alongside intersection controllers to help ensure emergency vehicles can move through intersections rapidly and safely, and public transit vehicles can avoid delays and adhere to schedules.

When an emergency vehicle needs to navigate an intersection, the Opticom system on-board the vehicle sends a request to the intersection’s controller ahead of its arrival, which turns the light green when it can do so safely, clearing a path to enable the vehicle’s expedited passage. If a public transit vehicle is running behind schedule, it can send a request for a green signal where possible.

    Jacksonville, US expands traffic signal priority
    Global Traffic Technologies (GTT) has contracted with Jacksonville Transportation Authority in Florida for the expansion of its latest-generation GPS-equipped Opticom transit signal priority (TSP) system. The Opticom TSP system allows public transportation agencies to extend or truncate green cycle times at traffic signals for more accurate schedule adherence. In turn, transit vehicles are on the road less, which reduces fuel and fleet costs for more profitable operations. In Jacksonville, additional bu

    Emergency response teams in the densely populated town of Brookhaven, New York, respond to more than 5,000 emergency calls every month. To enable fire-fighters and emergency services to meet the demand, town officials made the decision to upgrade to Opticom GPS priority control technology on more 500 fire trucks and at almost as many intersections. Opticom GPS uses a global network of GPS satellites to calculate vehicle speed, direction and precise location to pre-empt signals even around corners or obs
