Supervisors authorize contract to upgrade traffic signals

The San Diego County Board of Supervisors voted 5-0 June 23 to authorize the advertisement for bid and subsequent award of a construction contract to rehabilitate or update traffic signals at 64 intersections, including nine in Fallbrook and one in Bonsall.

The replacements are expected to improve pedestrian safety, enhance traffic flow, and reduce traffic congestion and air pollution. The work includes cabinet, controller, and video detection replacements.

“It’s just upgrading old electronics,” said Murali Pasumarthi, the traffic engineering manager for the County of San Diego’s Department of Public Works. “It’s part of the maintenance to replace controllers and cabinets that have had some problems in the past.”

The Department of Public Works operates and maintains 185 traffic signals in unincorporated San Diego County, including 20 in Fallbrook and two in Bonsall (a traffic signal at the intersection of a county road and a state highway is maintained by the California Department of Transportation, so Caltrans is responsible for all signals along State Route 76 or off Interstate 15). When traffic signal equipment surpasses its service life, replacements are needed to ensure the signal’s reliability.

In November 2006 the state’s voters approved Proposition 1B, which provides $2 billion for California’s local streets and roads. In October 2009 the county supervisors included the signal operations improvement project in the county’s list of projects using Proposition 1B funding. The Proposition 1B funding was received on May 14, so it will become fund balance for fiscal year 2010-11 when the signal project will begin. The signal improvement work is scheduled to commence in September 2010 and be complete by September 2011.

The signals at the intersections of Ammunition Road and South Mission Road and East Vista Way and Gopher Canyon Road will be provided with cabinet equipment replacement. Controller replacements will take place at the intersections of Fallbrook Street and Magarian Road; Main Avenue and East Mission Road; East Mission Road and Stage Coach Lane; South Mission Road and Stage Coach Lane; South Mission Road and Sterling Bridge; South Mission Road and Winter Haven Road; and West Mission Road and Pico Avenue.

Video detection improvements will be provided for the signals at East Vista Way and Gopher Canyon Road; South Mission Road and Olive Hill Road; and South Mission Road and Stage Coach Lane.
