Two new traffic signals--one on the east side of town and another where Bernal Avenue meets Interstate 680--will be activated on today, the city announced.
A traffic signal at the intersection of Vineyard Avenue and Pietronave Lane is expected to improve access to Vineyard Avenue for residents, particularly during the morning and evening peak commute periods. A vertical grade at the intersection limits sight distance, prompting the need for a traffic signal, according to city spokeswoman Joanne Hall.
City traffic engineer Joshua Pack said there are future plans to add a crosswalk for pedestrians, cyclists and equestrians that will allow people to connect to a future trail system there, located at the south side of Shadow Cliffs Regional Recreation Area, but the city has set no specific timeframe.
"It will have pedestrian crossings on both sides crossing Vineyard Avenue and also, an equestrian push button is being put in so people on horses can actually press the button and cross the street so they don't have to get off their horses," Pack said.
"Eventually, Old Vineyard Avenue is going to turn into a really nice trail and there will be a Vineyard Corridor trail running through portions of Vineyard and meandering its way east to west," he added. "That's in the planning stages right now."
A second traffic signal being turned on today is at the intersection of Bernal Avenue and Interstate 680. It's anticipated the signal will reduce the average delay at the intersection and providing protected left turns for vehicles exiting or entering the freeway southbound.
"The signal's going to provide improved access specifically for vehicles making a left turn onto southbound 680," Pack said. "Right now, the delay is pretty significant, especially during the morning."
City engineers, inspectors, contractors and subcontractors conducted final tests on the signals prior to activation, including a thorough analysis of the vehicle detection system, signal timing and operations parameters, pedestrian push buttons, and an emergency vehicle preemption system that allows fire and police vehicles to turn a red light green for quicker response to an emergency situation.
The new signal at Vineyard Avenue and Pietronave Lane, just east of Vintage Hills and Western Garden Nursery, is also in communication to the city's Traffic Operations Center, located in Pleasanton City Hall, through a wireless communications antenna located at the intersection. Upon activation, staff can remotely view fixed-in-place video detection cameras, modify traffic signal timing and receive alarms and event notifications in real-time, Hall said.
While the new signal at Bernal Avenue and I-680 will be operated by Caltrans, the city has installed a Closed Circuit Television (CCTV) camera at the intersection to monitor traffic conditions in the area.
The cost for both signals was $416,000 and funds came from mostly developer impact fees--monies that developers pay to offset the impact to traffic circulation in the area.
