9. Update Action Plan the TSOs continue to be met. Achievement of the TSOs depends upon successful imple- mentation of the actions, measures, and programs 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 achievement 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 ve- hicle ridership. The TSOs should be monitored, as part of the updating of the Action Plans. The following describes how each should be measured. Each jurisdiction should report the results of their monitoring activities to the TV T AC for review. Any TSO violations should be forwarded to the TVTe with recommended actions. Freeway Levels of Service. The TSOs are expressed both in terms of volume-to-capacity ratio (VIe) 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 auxil- iary lanes). Traffic counts can also be used to show duration of congestion. Freeway monitoring should be done by Caltrans or the C!v1A. 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 intersection lies. The in. tent of the TVTP is to maintain the intersection TSO at all signalized intersections. How- ever, to avoid extensive data collection, each jurisdiction should establish a list of critical intersection for monitoring. Mode Split. Mode split is virtually impossible to measure in the field, except through exten- sive home interview and work place surveys. These data are available every decade from the U.S. Census and periodically from MTC. In between times, transit ridership should be monitored as a surrogate for mode split. The mode split goal of the TVTP can only be met if transit ridership increases annually. The transit operators routinely collect and report annual ridership. 18 April 2000 Page 69
