DRAFT 3. Circulation Element Table 3-7 illustrates the existing and buildout levels of service for the signalized intersections in Pleasanton. As Pleasanton approaches buildout, the congestion levels, especially near the freeways, a=unroach the acceptable limits identified as LOS D. Figure 3-5 shows existing levels of service while Figure 3-6 shows buildout levels of service with additional mitigations. At buildout, except for exempted Downtown and gateway intersections the entire city would operate at level of service D or better with all mitigation measures implemented, as detailed in Table 3-8 and Figure 3-7. Traffic Safety On an ongoing basis, the Traffic Engineering Division in consultation with the Police Department monitors collision trends in Pleasanton. The City annually ranks intersections based on collision freduency and identifies intersections with the highest number of collisions for more detailed analysis of collision causes and possible solutions. Efforts to reduce congestion and calm traffic also help to reduce collision-risk factors such as speeding and red-light running In addition to monitoring the existing roadway network's traffic safety, traffic studies for new development should also address roadway safety. Project traffic studies should address necessary improvements to network traffic safety as well as to pedestrian, bicycle, and existing local roadway safety needs. Traffic safety analyses should address project impacts with mitigation and improvement measures. These measures should focus on the arterial network's level of service improvements as well as on general roadway saw For traffic safety the City has established minimum roadway right-of--way widths -including sidewalks, parking, landscaping, and bicycle lanes - ranging from 30 feet for alleys to 166 feet for thoroughfares with frontage roads. According to the Municipal Code, new residential roadway rights-of--way should be between 42 and 60 feet wide, depending on roadway type.3 During the Planned Unit Development~rocess, the City may approve narrower roadways, if these would provide more safety for pedestrians while still providing adeduate bicycle and motor vehicle access. Future Conditions Traffic Projection Model In order to forecast General Plan buildout traffic volumes and Llevels of service, the City of Pleasanton has developed a comprehensive traffic forecasting model. Summarized briefly, the model utilizes information regarding the city's existing and future land uses as well as the existing and future roadway network to project traffic volumes and the performance of major intersections within the city. 3 Pleaaantan Munici~ad Code. 19.36.040 Streets and thoroughfares -Width and geometries 2007.
