@sfchronicle: It sounds absolutely dire. Proponents of a Bay Area transit sales tax measure warn that rejecting it on Nov. 3 could unleash a traffic apocalypse, with rush hour delays on the Bay Bridge potentially doubling. A new analysis by the Chronicle and UC Berkeley’s Mobiliti Labs found that the added congestion may be more modest, though it would hinge on the depths of cuts to BART service and riders’ ability to adapt. Currently, it takes about 13 minutes to cross the bridge westbound during peak morning hours. That figure could rise if BART were to close 15 stations, a concept officials presented earlier this year to illustrate how they could possibly slash service if the rail system were to enter a death spiral. Just how much it would change depends on what displaced riders do next. Read more via the link in our bio.
