Existing Levels of Service - In most cases, existing levels of service will be certified and supplied by the City of Pleasanton. Where no such existing surveys exist, the traffic engineers conducting the new study shall perform new peak hour traffic surveys to determine existing levels of service. The methods described below in Method of Calculating Level of Service, shall be utilized. Existing levels of service are listed in Table III. Appendix 1 contains a listing of current existing traffic volumes, volume-to-capacity ratios and levels of service at key intersections in the City of Pleasanton, as of the latest Citywide traffic survey. Trip Generation Rates - Trip generation rates shall be certified by the City of Pleasanton prior to commencement of the traffic study. Current approved rates are shown in Table IV. These rates are derived from standard sources and represent conditions with standard vehicle occupancy and working hours and with no transit usage. Where previously certified rates do not apply, a traffic engineer may request the use of new rates. Ride Sharing - For employee-intensive uses such as office buildings, trip rates may be reduced to account for the effects of ridesharing. The text of the report shall justify the use of any ridesharing percentage adjustments. The current maximum allowable assumption is 10 percent. Normally, ridesharing reductions shall not be applied to such uses as hotels, restaurants, or retail-financial and medical-related uses. Transit Reduction - Daily trip rates may be reduced for those land uses potentially served by transit. Transit can include the local proposed Dublin/Pleasanton transit service, any public or private shuttle service connecting with BART or other long distance commute service. The effects of vanpooling would not be considered as "transit" but would instead be considered as a portion of "ridesharing". The use of any transit percentage adjustments shall be justified in the text of the report. The current maximum allowable transit use assumption is 5 percent. Normally, transit reductions would only apply to employee-intensive uses and residential uses. Uses not expected to have transit reductions would include hotels, restaurants, co~ercial and financial uses. Local Trips - Existing trips, or trips accounted for in previous traffic studies or diverted existing trips shall be accounted for with this adjustment. Joint purpose trips would also be accounted for with this adjustment factor so that double counting of trips is avoided. Typical "local trip" adjustment factors would be 10 percent for employee-intensive uses, 50 percent for commercial use and no reductions for hotels and restaurants. Peak Hour Percentages - After the daily trip adjustment factors have been applied to produce daily trips, the peak hour trips are to be calculated. The percent of the peak hour will be based upon -2-
