City replaces traffic control backup batteries

The city of Santa Clarita installed new battery backup systems (BBS) as part of the city's traffic signal maintenance program.

BBS provide reliable emergency power to traffic signals in the event of power failures or interruptions, attributing to a reduction in traffic congestion and the likelihood of accidents.

BBS batteries are rechargeable and last for five years. During full traffic signal operation, the batteries are continually recharged.

When a power outage occurs, the BBS is activated and can support the traffic signal for two hours until power is restored.

"In addition to numerous city intersections, signalized intersections adjacent to railroad crossings are now also equipped with the battery backup system, potentially preventing injury and accidents," Mayor Frank Ferry said. "By providing emergency power during an outage, the BBS allows traffic signals to continue to operate, clearing vehicles and from the railroad tracks and allowing pedestrian travel to continue safely at intersection crosswalks."

The new BBS alerts city staff when the backup systems are engaged due to power failures and other interruptions, providing statistics on how often the backup systems are activated.

In addition, city staff can directly monitor the status of all BBS systems from the city's Traffic Operations Center.

Installation of the new BBS replaces previous batteries installed between 2001 and 2003. When batteries are replaced every five years, the disposal is performed by the manufacturer at no cost to the city.
