Signal Modernization Project in Oakley


City staff has been working over the past weeks to complete various signal improvements in Oakley. The Laurel Road/Empire Avenue and Main Street/Cypress Road intersections now have video detection cameras at all approaches to the intersection to improve vehicle detection. Fine tuning of the signal timing is also taking place to ensure the intersections are operating at an optimum level of service. Crosswalk markings are also being refreshed to improve safety for pedestrians. Signal modifications and striping at O’Hara Ave/Carpenter Road will be complete in the upcoming week to add protected left turn lanes on O’Hara Avenue, which will help improving the traffic operations at this intersection.

The overhead cameras you see at a traffic signal are solely for detecting the presence of vehicles in order to provide the best distribution of green time based on traffic demand. They are cost-effective replacements for in-ground induction loops that are cut into the pavement.

The cameras are not focused on you the driver, but instead on your vehicle as it moves towards the intersection. As your vehicle enters defined areas or “zones” within the camera’s field of view, the camera’s processor detects a change in the “zone”. An output is sent to the traffic signal’s controller (the computerized “brain” housed in a nearby metallic cabinet controlling the intersection’s timing) that says a vehicle is requesting green time for its direction.
