TABLE 4.3.4 2010 TI Calculation Comparison Roadway Segment Location 2010 No Project 2010 Proposed Project Unne Road -West of MacArthur Drive 12.5 12.5 MacArthur Drive - North of Line Road 11.5 11.5 Urine Road - East of MacArthur Drive 13.0 13.0 MacArthur Road - South of Unne Road 12.0 12.0 Chrisman Road - North of Line Road 12.0 12.0 Table 4.3.4 indicates that the addition of project traffic in 2010 would not increase the TI values and } therefore would not result in changes to the design requirements for the roadway structural sections. Intersections Operating Conditions Figures 4.3.2 4.3.3,4.3.4,and 4.3.5 display the intersection traffic volumes analyzed for this study. For each intersection the figures also indicate laneage and right-of-way control device. Figure 4.3.6 displays the level of service results of the intersection operations analysis. Appendix C contains the technical calculations for the intersection operations analysis. According to the analysis results, the study intersections do not exceed the evaluation criteria standard of LOS D under any analysis scenario. 1 Although this analysis focuses on intersections in the vicinity of the project, Caltrans responded to the NOP with concerns over potential operational impacts at the intersections of Chrisman/1- 1 580/State Route 132 and Corral Hollow/1-580 as well as other state highway intersections in the vicinity. Traffic distribution and assignment for the project indicates that project trips would not access the Corral Hollow/1-580 intersections but that some project trips would access the C W- State Route 132 intersection. Approximately 10 compost/recyclable track trips _ would access the intersection in 1995 increasing to 27 by 2010 on a daily basis. Over the course of the day, this level of truck traffic would not impact the operation of the intersection. Safety Conditions An NOP response raised the question of safety at the intersection of MacArthur Drive and Unne Road. Table 4.3.2 above indicated that over the past five years there were a total of &eV49A four --- accidents, none of which involved fatalities These accidents appear to be the result of driver decisions and are nota function of roadway design conditions. In support of this conclusion is the fact that the County does not list the intersection as a high accident location warranting safety improvements. As such, there is not sufficient evidence to conclude that the addition of project traffic through the intersection will increase the existing rate of accidents at this location. Public Transit Service Project traffic would not place new demand on existing or planned public transit service nor would it after existing or planned service. x ER-93-1 (9-27-93)
