I-66 Multimodal Study Final Report - Virginia Department of ...

Multimodal PackagesCost EstimatesPackage 3 has a high estimated cost due to the highway capacity expansion, as shown inTable 3.10. The highway costs reflect the addition of a lane in each direction and controls associatedwith HOV restricted operations during the peak periods. There is no tolling option inthis package, reflected by the lower highway cost than Package 2. The transit costs reflect theadded transit service. The majority of the transit cost is for operating expenses, which will beincurred annually. Transit costs do not include additional costs associated with increasedmaintenance and storage needs.Table 3.10 Package 3 Cost SummaryCapital ($2011) Annual Operating ($2011)Highway $340-665 million $3 millionTransit $6 million $26 millionAppendix D provides more detailed documentation of the cost estimation assumptions.Key FindingsThis package adds lane capacity and provides a Bus/HOV 2+ only lane in the reverse peakdirection. There is a slight increase in HOV 2 usage but HOV 3+ usage does not increase.Multimodal mobility increases during the off-peak periods, when the added lane on I-66 isopen to all traffic (not during the peak commuter periods due to the HOV 3+ requirement).This package improves travel times for HOV and transit.3.7 Package 4 – Support of Enhanced Bus ServiceDescriptionThe key elements of Package 4 include:Increased transit service for all routes entering the study area, including increased frequencyon local, commuter, and regional bus services.Headways on individual routes, that did not already have headways less than 15 minutesand were not part of trunk line services, were set at a minimum of 15 minutes in the peakand 30 minutes in the off-peak.Trunk line routes, which did not have a combined headway less than 15 minutes, were setfor a combined headway of 15 minutes in the peak and 30 minutes in the off-peak.
