The traffic model forecasts that if the roadway were not widened, the driving time for local drivers on local roadways would stay about the same (+ 1 hour collectively) during the 4:30 to 5:30 PM peak hour. The traffic volume change is so minor that the additional driving time is most likely due to the lower travel speeds associated with 2-lane roads versus 4-lane divided roadways. By removing the Dublin Canyon Road widening from the 1996 General Plan Roadway Network, local drivers would collectively drive about 18 miles less along local City roadways to reach their destinations during the 4:30 to 5:30 PM peak hour. Unfortunately this shift in traffic may be related to more vehicle shortcutting along Laurel Creek Drive instead of using Foothill Road and Dublin Canyon Road. The traffic model was run to forecast how traffic would change if the Dublin Canyon Road widening were removed from the 1996 General Plan Roadway Network. The following two tables summarize how evening peak hour driving time increases, while diving distances decrease for local drivers when the road widening is removed from the roadway network.
