Silver Line and Bus Network Can Be Arranged To Work More Efficiently

It may shock a few non-Tysons residents, and maybe a few in town, that Tysons has a very solid bus network which can get you to several Metro Stations, the Pentagon, DC, and Arlington already in existence. It seems many are unaware of the Tysons Transit Center located on Jones Branch Drive, although on a typical weekday rush hour the station does become quite busy. The design and layout of those bus routes were based on a city without metro stations of its own. Several of the buses routes are designed to move people to the orange and blue rail lines. The Silver line will of course allow major changes, and more efficient consideration of people movement, to be incorporated into the system.

As part of the comprehensive plan and transportation master plan for Tysons, Fairfax County has been preparing a study to analyze the best circulator system options. Currently there are several options ranging from only two routes (a decrease to the number of circulators and not a serious option) and five routes (filling in the gaps where the four metro stations can’t reach). I think the study is fairly solid, other than that two route idea which is a complete rip-off. One thing I want to note to readers is that more routes isn’t necessarily better. The key is the frequency of the routes and the time frame in which they run. It would be preferable to have buses that run at the same frequency as the rail headways at the silver line stations, as this will allow for bus routes to be kept in sync with the rail system, and reduce waiting times at transfers. To this point, it may be better for a 3 route system with 4 buses running at rush, instead of 5 routes each with only 2 buses running at rush.

The discussion of the circulators is one of those elements that residents should be a part of and educate themselves so that they can make their best case in advance of decisions being made in 2013. One thing that hasn’t been discussed is what happens to the inter-city bus networks that are now redundant systems to the silver line?

One such route is the 23A and 23C. Currently this system starts from the Tysons Transit Center, does a lap around the mall, back down International Drive, and then finally heads out of town towards Crystal City as well as Langley. This system spends 30 minutes of its route simply circling Tysons, and will pass by three metro stations once Silver line is up and running. This is a terrible use of limited transit funds. The key will be gaining access for people from Tysons to those same destinations (Crystal City, Arlington, and Langley). By rearranging the map to remove the Tysons component, the route can now start at the Silver Line McLean station, avoid much of the worst traffic, and make straight shots to each terminal.

Right now this system takes 3 hours to make a full lap to Crystal City from Tysons. That means at rush hour it runs 6 buses on this route in order to maintain a 30 minute headway. Changing the Tysons terminal to the McLean silver line station will reduce the lap time to only two hours. To maintain the current service level the system would only need 4 buses, or a 33% reduction in operation cost. Of course, these buses could remain and the headways could be reduced to 20 minutes and improve mobility for residents in McLean, Arlington, Tysons, and Crystal City also. Either way, maintaining the current route would be wasteful folly.

Is there a bus line that you believe could benefit from the silver line that you want to inform us about? Let us know and we will take a look. The point is not to reduce our transit dollars, but to use them better to assure more mobility and options for people coming to and leaving Tysons.

    Maps are hard to read even enlarged but we need a bus coming down Beulah Rd to serve communities just like one on old courthouse road.

      Connection between Vienna and Tysons will be very important, especially in eastern Vienna. I believe the 28T is another example of a bus route which should be re-aligned to better serve intercity trips instead of acting like a circulator in tysons. Currently it runs between West Falls Church and West Park Transit via Old Courthouse/Route 7/Gosnell. It could instead run from the Tysons Central Station, down 123 to Beulah, up to what would become a bus only onramp onto the DTR, and then off at Route 7.

      That would serve a significant residential component, as well as additional access to Route 123 to some of the most popular commercial/retail areas of Church Street and Maple Ave.

      Good suggestion

    Would these routes replace the FF County Connector route 427? None of these options have busses that go by either gate of the Rotonda. We have many older residents for whom walking to one of the new metro stations would not be feasible. Also, these routes won’t be efficient for local residents if you can’t go directly from the transit station to a the closest metro station.

      Beyond the age of the residents at Rotonda is also the fact that Rotonda is the single highest density residence in Tysons and therefore will have far greater transit demands than other properties. I believe there will be bus options for Greensboro and Spring Hill based on this map as well as the continued operation of the Transit Center. The question becomes, can the 425 and 427 be better positioned to remove travel to WFC, and instead focus on transporting residents to the Tysons stations, and therefore run more efficiently with less headways (time between buses)
