Morning Peak Hour Cut-through Traffic The 1996 General Plan Roadway Network Model projects that about 590 cut-through vehicles use portions of Bernal Avenue during the morning peak hour. At Buildout, or the year 2025, 1-580 is forecast to be congested in both directions and, thus, cut-through traffic is present on Bemal Avenue almost evenly split between the eastbound and westbound direction. Based on the miles traveled and travel times for cut-through traffic, it appears that not widening Bernal Avenue would divert some cut-through vehicles onto the collector streets in the downtown area. The number of cut-through vehicles on City streets would remain about the same during the morning peak hour if Bernal Avenue is not widened as shown in the 1996 General Plan. Morning Peak Hour Congestion Levels At the 135 study intersections, traffic volumes collectively decrease by about 1,380 vehicles per hour (VPH) during the morning peak hour when the Bernal Avenue widening is removed from the 1996 General Plan Roadway Network. Traffic collectively decreases by about 650 VPH at the 24 intersections in the City with 35 seconds or more of average delay, and collectively decreases by 730 VPH at the 111 other study intersections when the roadway widening is removed from the network. Due to the number of possible roadway alternative combinations, the resulting LOS calculations will be performed based on future traffic model runs based on a more refined roadway network alternatives combination. The above traffic increases or decreases may occur on non-critical approaches to many intersections and have little impact on congestion at the intersections. Also note that the volumes described herein are only those at the study intersections. Shifting traffic from a route with many study intersections to one with few will "decrease" vehicles at study intersections, although traffic as measured by miles traveled or total intersections affected may actually increase. The volume of traffic at study intersections is a possible short-hand way to estimate possible impacts to levels-of-service, but it is only an approximation. Care should be taken to observe where traffic is shifted. Whether this traffic can be accommodated on the new route and its intersections cannot be known until further analysis. Evening Peak Hour Bernal Avenue Users - East of First Street The following map shows that about 2,250 Pleasanton drivers would use the section of Bernal Avenue just east of Sunol Boulevard during the evening peak hour if the roadway were widened as part of the 1996 General Plan Roadway Network. In addition to these local users, about 1,200 cut-through drivers would use this roadway, about 1/3 westbound and 2/3 eastbound. SR 05:027 Page 29
