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

Multimodal PackagesLevel of Service PerformanceThe following figures show the level of service for the highway and transit systems assumedfor Package 3. Package 3 added capacity to I-66 but restricted it to HOV 3+ inbound andHOV 2+ outbound. In the inbound direction all three lanes were restricted to HOV 3+. In theoutbound direction only the new added lane was restricted. The levels of service here are verysimilar to the CLRP+ Baseline. Due to the lane restrictions, the added capacity attracted veryfew new users. It did provide for a slight improvement in the outbound bus speeds.The major arterials in the study area showed similar levels of service to the CLRP+ Baseline.There was no real difference in performance. This was representative of the VMT by level ofservice which showed similar levels of congestions as the CLRP+ Baseline.Package 3 improved transit service along U.S. 50. This resulted in an improved quality level ofservice for transit. The transit service shows improved frequency for buses. Along U.S. 50 atthe western end of the study corridor there are 22 buses per hour in Package 3 compared to 11buses per hour in the CLRP+ Baseline.The coverage area is the same as in the CLRP+ Baseline scenario, with added levels of servicefeeding into the Metrorail system along existing bus routes. Load factors are summarized forPackage 3 in Table 3.9. Package 3 shows lower load factors on Metrorail at each of the cutlines,consistent with an increase in bus and SOV travel. Meanwhile, the bus load factors are relativelyunchanged for Package 3 at all cutlines as compared to the CLRP+ Baseline scenario.Table 3.9Package 3 Transit Load Factors for the Morning Peak PeriodMetrorail Bus Peak Period Bus Service(Passenger per Car) (Passengers per Bus) (Buses per Hour)Cutline CLRP + Package 3 CLRP + Package 3 CLRP + Package 3Beltway 36 34 36 38 37 51Glebe Road 67 66 33 33 68 87Clarendon 85 83 35 35 71 89Potomac River 90 89 39 37 44 593-44 I-66 Multimodal Study
