number of cut-through vehicles on City roadways by about 20 to 50 vehicles during the morning peak hour. Morning Peak Hour Congestion Levels At the 135 study intersections, traffic volumes collectively decrease by about 2,010 vehicles per hour (VPH) during the morning peak hour when the Foothill Road widening is removed from the 1996 General Plan Roadway Network. Traffic collectively decreases by about 620 VPH at the 24 intersections in the City with 35 seconds or more of average delay, and collectively decreases by 1,390 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. Morning Peak Hour School Traffic Significant congestion occurs along Foothill Road approaching and adjacent to Foothill High School during the morning peak hour. Traffic backups all the way to Bernal Avenue and West Las Positas Boulevard are not uncommon. This impacts High School traffic, motorists trying to get to Lydiksen Elementary and all other motorists in the area. Widening Foothill road to four lanes from West Las Positas Boulevard to South Muirwood Drive would allow local drivers to pass the stopped northbound and southbound queues near the High School. This would significantly reduce travel time along Foothill Road without requiring significant widening north of West Las Positas Boulevard. Traffic Safety Widening sections of Foothill Road between South Muirwood Drive and Castlewood Drive to provide a 2-way left turn lane and bike lanes / paved shoulders, is not recognized by the traffic model as capacity enhancing. With or without these features, the roadway is modeled based on the two through lanes. However, this widening would significantly improve motor-vehicle, pedestrian and bicycle safety along Foothill Road in areas that currently have no shoulders, limited sight distance, and no left turn storage. Evening Peak Hour Foothill Road Users The following map shows that about 2,280 Pleasanton drivers would use the section of Foothill Road just south of West Las Positas 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 130 cut-through drivers would use this roadway, primarily in the southbound direction. SR 05:027 Page 38
