Mobility OptionsFigure 2.17 Interline Connection – Option FKey FindingsThis option changes the operating plan for Metrorail to provide direct service between theRonald Reagan Washington National Airport, South Arlington, the Rosslyn‐Ballston corridor,and points west along the Silver Line. This option provides additional service on the Orange/Silver Lines between Court House and East Falls Church and direct connections to new markets.Flexibility of Metrorail is enhanced, but ridership effects in the study area are modest.Other findings based the MOEs detailed in Table 2.3 include:Levels of congestion remain relatively constant when compared with the CLRP+ Baselinescenario;Total PMT in the study area increases over the CLRP+ Baseline scenario as shown inFigure 2.18, with the largest increase of PMT occurring on freeways; Transit mode share increases slightly over the CLRP+ Baseline scenario, with about 300more transit trips to and from the corridor. The majority of these trips are within the studyarea or from the west of the study area; andMetrorail throughput increases slightly at all of the cutlines, except the Potomac River cutlinewhich is probably related to the new direct rail service to points south.An alternative Metrorail operating plan for the corridor also was studied, in which half of theeastbound Orange and Silver Line trains made use of a second interline connection betweenArlington Cemetery on the Blue Line and L’Enfant Plaza on the Yellow/Green Lines.
