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

Multimodal PackagesCost EstimatesPackage 4 has the highest transit capital and operating cost, which reflects the high level oftransit service programmed for this alternative, as shown in Table 3.13. Transit operatingexpenses are incurred annually. Transit costs do not include additional costs associated withincreased maintenance and storage needs. The highway cost reflects the construction of theshoulder lane along U.S. 50, which is designed as a bus only lane.Table 3.13 Package 4 Cost SummaryCapital ($2011) Annual Operating ($2011)Highway $211 million $1Transit $9 million $46 millionAppendix D provides more detailed documentation of the cost estimation assumptions.Key FindingsThis package focused on enhancing transit service throughout the study area. It had the highestnumber of commuters using transit and the lowest number using single occupant automobiles.It produces slight decreases in overall vehicle travel (VMT) and congested VMT.3.8 Integrated Corridor ManagementICM brings together a variety of technology elements, providing drivers, transit users, carpoolers,and bicyclists with information to be able to make informed transportation decisions inadvance or in real time. When ICM elements are implemented, users can expect greater traveltime reliability and more efficient use of corridor infrastructure. The I-66 Active TrafficManagement (I-66 ATM) project is addressing several such improvements. Specific elements ofICM considered in the I-66 Multimodal Study include:Enhanced Ramp Metering (I-66 ATM);Dynamic Merge (Junction Control) (I-66 ATM);Enhanced Dynamic Message Signs (I-66 ATM);Continuous Closed-Circuit Television Coverage (I-66 ATM);Speed Harmonization;Advanced Parking Management System;I-66 Multimodal Study 3-59
