devices. The four-lane configuration was originally designed in the early 1980's, and Stoneridge Drive was planned and built to be this inter-city connector. There is no planned new development along this section of West Las Positas Boulevard, so future traffic volumes should remain at current levels. To analyze the pros and cons of widening this roadway from a traffic perspective, the traffic forecasting model was used to study roadway users during the morning and evening peak hour to assess: · Who would use the widened roadway (local or cut-through)? · Where were Pleasanton drivers coming from or going to as they used the road? · What was the purpose of the trip (work, school, shop, recreation, etc.)? What impact did the roadway widening have on driving times and driving distances for local drivers? · How did the roadway widening effect traffic volumes at 135 City intersections? · How did the roadway widening effect cut-through traffic in Pleasanton? The following is a summary of the traffic forecast model outputs assuming Buildout of the 1996 General Plan Land Use and Roadway Network. · The only change noted was that not widening the roadway would reduce travel speeds along this section of West Las Positas Boulevard relative to a 4-lane divided roadway. Not widening the roadway would result in a collective driving time increase of about four hours of travel time during the morning and evening peak hours. · The miles traveled by local drivers remained the same in both alternatives. · No cut-through traffic uses West Las Positas Boulevard east of Fairlands Drive during the Morning or Evening peak Hours whether the roadway is two or four lanes wide. * The 4-lane and 2-lane alternatives resulted in the same Level of Service at all study intersections. Proposed Widening/History: Foothill Road to Muirwood Drive The 1996 General Plan Roadway Network assumed that between 2000 and 2005, West Las Positas Boulevard would be widened to be a 4-lane divided road from Foothill Road to Hopyard Road. The interchange portion of this planned network, including overpass widening, is addressed under the "West Las Positas Boulevard Interchange" section of this report; this section covers that portion of the road between Foothill Road and Muirwood Drive. This section of roadway has the two center lanes undeveloped, with interim landscaping in place within the median. A part of the City's original 1960's planning which anticipated much more extensive development along Foothill Road and West Las Positas Boulevard being the only interchange with 1-680 north of Bernal Avenue (no Stoneridge Drive interchange was planned), this segment was installed as two lanes within a four-lane right-of-way by the initial area developers.
