Plan Implementation, Monitoring, and Review Monitoring Transportation Service Objectives The Transportation Service Objectives (TSOs) are the heart of the TVTP. While certain growth assumptions are a part of the plan, they serve merely to guide the specification of a planned transportation system and financing program. The TVTP does not control growth directly but indirectly through the TSOs. Under existing conditions, the TSOs relatihg to freeway and intersection levels of service are largely being met. Future growth should be matched with road improve- ments so that the TSOs continue to be met. Achievement of the TSOs depends upon successful implementation of the actions, measures, and progr3ms set forth in Chapter 9, "Action Plan." In Contra Costa County, if, following good faith implementation of the Action Plan, a TSO is not met, then the Plan would need to be reevaluated through the forum of TVTC and SWAT. Amendments to the Plan could include a relaxation of TSOs, a strengthening of actions, or a combination of these approaches. In Alameda County, the jurisdiction with the TSO violation can elect to modify growth rates, improve the facility, or seek a lower TSO standard through the amendment process set forth in this chapter. The TSOs related to mode split and average vehicle ridership are goals for achieve- ment by 2010. They need to be monitored and adjustments to the plan made if progress is not being made. Progress should be defined as increasing transit ridership and increasing average vehicle ridership. The TSOs should be monitored every two years. The following describes how each should be measured. Each jurisdiction should report the results of their monitoring activities to the TV TAC for review. Any TSO violations should be forwarded to the TVTC with recommended actions. Freeway Levels of Service. The TSOs are expressed both in terms of volume-to-capacity ratio (V/C) and hours of congestion. Volume-to-capacity ratio and hours of congestion can be measured with traffic counts or speed runs and should apply to mixed-flow lanes only. The plan uses a capacity of 2,200 vehicles per lane per hour (1,100 vehicles capacity for auxiliary lanes). Traffic counts can also be used to show duration of congestion. Freeway monitoring should be done by Caltrans or the CMA. Intersection Levels of Service. Intersection levels of service should be calculated using the VCCC program for AM and PM peak hours based on turning-movement counts. Intersection monitoring should be conducted by the jurisdiction in which the intersec- tion lies. The intent of the TVTP is to maintain the intersection TSO at all signalized intersections. However, to avoid extensive data collection, each jurisdiction should establish a list of critical intersections for monitoring. Barton-Aschman Associates, Inc. 235
