In a move unprecedented in the Bay Area, the citys traffic engineers have created a traffic signal with attitude. It senses when a speeder is approaching and metes out swift punishment. Residents and commute-jockeys said Tuesday that the light, which the city plans to unveil today on Vineyard Avenue at the intersection of Montevino Drive, is either an inspired leap into the future or a blatant example of government overzealousness. Its kind of big-brotherish, but sometimes its the price we pay for safety, said JoAnne Brewer, 49, who walked her golden retriever past the new signal Tuesday morning and predicted it would be a success. Drivers on the two-lane Vineyard, as they approach Montevino, will see an electronic sign that gives the speed limit - 40 mph heading west and 35 mph going east - then flashes their actual speed. A camera about 350 feet from the intersection measures speed and tells the light whether to do its business. Traffic engineers plan to give drivers a few miles per hour of wiggle room. But once speeding is detected, the red light will turn on for at least 10 seconds - or 30 seconds-plus if cross traffic is waiting. Its all a little too much for Ken Pattee, a 52-year-old construction inspector from Livermore who sometimes rides his Harley-Davidson down Vineyard Avenue. Its depriving you of another one of your liberties - going fast, Pattee said. If they implement it everywhere, there will be nothing but red lights. The Bay Area is increasingly consumed with its traffic woes, as seen in a recent fight over neighborhood traffic barriers that divided Palo Alto residents. Top political issue Pleasanton has become a capital of traffic hand-wringing, with a spot between Interstates 580 and 680 that invites cutting commuters.
The Police Department even allows citizens to borrow radar guns to document speeders near their homes and send out warning letters to offenders. The punitive nature of the signal on Vineyard appears to have the united support of neighbors and the Police Department, which hasnt seen an unusual number of accidents on the route but envisions a low-cost way to make people feel safe. The intersection sits near large stucco and brick homes with manicured landscaping. The route, connecting downtown Pleasanton to the Ruby Hill gated community and Highway 84 in Livermore, is not the country road it used to be, and it attracts a healthy stream of regional commuters. Many neighbors are so peeved with the popularity of the road that they didnt want a traffic signal at all at Montevino because it would allow traffic to flow better than the stop sign it replaced. At least the stop signs made speeding impossible and persuaded some commuters to steer clear, neighbors said. Pleasanton public works director Rob Wilson said the city has no plans to build more of the signals. Mark Senkle, who heads traffic enforcement, said, If it works, Id like to see it done in a few other areas in town. Thousand Oaks light At least one other place in California has put together a traffic signal that is deputized against speeders. The Ventura County city of Thousand Oaks installed one in 2000 that Pleasanton traffic chief Jeff Knowles, who used to work in Thousand Oaks, has been watching closely. The people who were concerned about speed are pleased with it, but youll hear a different story from some of the users of the road, said Thousand Oaks senior civil engineer Jim Mashiko. Pedestrians, for example, must be given the green on all four crosswalks in the intersection at the same time, so they are not confused by a sudden yellow and red aimed at a speeder. In addition, red rage could become an issue as drivers can be guilty by association if a speeder is just in front of them, just behind them or moving simultaneously in the opposite direction. Pleasanton plans to address at least one of those issues: the opposite- direction speeder. The Pleasanton signal will allow a red light to shine in just one direction, letting the light stay green for the nonspeeding driver in the opposite direction. In such cases, any cross traffic will continue receiving the red light.
