Where Are Silver Line Riders Going?

October 9th, 2014 8 comments

Ridership patterns on the Silver Line show that Metro’s new line is serving a truly regional market.

Now that school is back in session, the new Silver Line just completed its first full week where “normal” travel patterns are beginning to emerge. Ridership is strong, but where are these new passengers going? The diagram below shows destinations of all riders entering a Silver Line station in the week of September 8-12, 2014.

Early Ridership on the Silver Line

October 8th, 2014 6 comments

After just two months, ridership on the Silver Line is off to a solid start: Wiehle Ave is already over projections, reverse commuting is strong, and more. 

Now that school is back in session and most summer vacations over, here is an in-depth look at the week of September 8-12, 2014, when “normal” routines may have begun to emerge.

At around 15,000 entries per weekday, the Silver Line is off to a solid start.  Compared to the official projections from the 2004 Final Environmental Impact Statement (FEIS), we are achieving about 60% of the ridership projected for the end of the line’s first year:

Typical Weekday SV Ridership vs. ProjectionsWiehle station is already over opening-year projections and shows the highest ridership of all the new stations.  Tysons Corner station is strong as well, but we still have room to grow at all four stations located in the Tysons area.

Looking at ridership by time of day shows the Wiehle is a commuting powerhouse, but also that a strong reverse commute market is emerging at the other stations:

SV Ridership by 15-minute increment

  • McLean (in blue) is showing an early lead as a a “traditional” commute station, where most riders enter in the morning.
  • Tysons Corner is much more dominated by reverse commuters, and its morning rush extends into mid-morning (around 10:00am).  Evening ridership at Tysons Corners is also heavy. (More on off-peak ridership at Tysons coming soon)
  • Greensboro and Spring Hill show relatively light ridership so far, but ridership is expected to grow over time as development catches up with the new station.

What do you think?  Have you taken the Silver Line on a weekday? What was your experience?

The raw data by quarter-hour interval underlying this analysis is available in two formats: by station alone (2MB, .xlsx), and by origin-destination station (3MB, zipped tab-delimited .txt).

Nationals Playoff Games and Metrorail Ridership

October 3rd, 2014 No comments

When the Nationals reached the playoffs in 2012, about 12,000 fans per game took Metrorail – from all over the region, and even late at night!

Now that the Nationals have clinched a spot in the playoffs, Nationals Park will once again host October baseball beginning this afternoon. How many fans might take Metrorail to and from the game?

To answer that, let’s look back to 2012, the last time the Nats reached the playoffs. Games 3, 4, and 5 of the National League Division Series (NLDS) were played here at Nationals Park – Wednesday at 1:07 pm, Thursday at 4:07 pm, and Friday at 8:37 pm. Attendance at all three games was around 45,000 people. Here’s what ridership (Metrorail system entries) looked like at Navy Yard-Ballpark station on those days:

Nationals Ridership_NavyYard_NLDS2012_byHalfHour_v2

The sheer volume of passengers through Navy Yard station were impressive.  Sustaining over 4,000 entries per half-hour for nearly two hours is roughly equivalent to 4-lane highway, and exceeds what even the busiest stations achieve on a typical day.  For comparison, normal peak-of-peak volumes through Union Station, Metro Center, and Farragut West rarely exceed 3,000 entries per half hour.

Off-Peak Ridership at Tysons Corner is Strong

September 24th, 2014 6 comments

Even though Tysons Corner station on the Silver Line is only two months old, off-peak ridership is particularly strong. Saturdays are busier than weekdays, and the station stays busy past 10:00pm. 

Tysons Corner station is already serving a solid reverse commute market, but ridership is also strong during midday hours, and reaches its peak during the afternoon rush and evening hours.

Tysons Entries - first 2 weeks

Tysons Exits - first 2 weeks

Ridership is fairly well balanced throughout the day, relative to other Metrorail stations.  There’s a clear reverse commute market exiting the station during morning rush and re-entering in the evening. In the evening, however, nearly just as many people are exiting the station as are entering the stations, suggesting the commuters are mixing with other riders bound for the malls or other activities.

Metrorail Riders Go Car-Free… Every Day!

September 19th, 2014 No comments

Many pledge to leave their car at home for a day on Car-Free Day September 22,but 20% of Metrorail riders don’t own a car and go car-free every single day!

Of course, Metrorail riders from zero-car households vary significantly across the stations – from over half of all riders at places like Columbia Heights, Benning Road, and Dupont Circle – to less than 10% at more suburban areas like Rockville, East Falls Church, or Franconia-Springfield.  The diagram below shows the share of riders who live in a zero-car household, by station:

RailMap-Diagram_CarFreeHHsPCT_forweb

Of course, ridership varies across stations too, so the next diagram shows the total number of rail riders from zero-car households:

RailMap-Diagram_CarFreeHHs_forweb

In addition to riders who are completely car-free, many others come from “car-light” households of one or no cars.  58% of Metrorail riders come from “car-light” households.  For many, access to Metrorail and Metrobus and other transit services is a big reason they can drop down to one or zero cars and still get around.  In fact, DC’s zero-car households number is climbing, with 88% of new DC households car-free.  For others, car ownership is a heavy financial burden they may not be able to afford. Stay tuned for a coming post which estimates riders who are car-free by choice, vs. by necessity.

Do you live in a car-free household?  How does Metro help meet your mobility needs?

DataDownloadFuzzyMay 2013 and 2014 Metrorail ridership data is available: what patterns do you see?

Following up on our last data download of rail ridership from May 2012, 2013 and 2014 are now available. These data now represent three “snapshots” in time of rail ridership, at a very fine level of detail.  This data can help answer questions, such as: where is ridership growth the strongest? Which destinations are becoming more or less popular?  How has off-peak vs. peak ridership changed?

A Half-Mile Walk to the Nearest Metrorail Station, Mapped

August 4th, 2014 19 comments

Here’s a map showing the walkable area around the nearest Metrorail station.

eGISBaseLTR_RailPedSheds NonOverlap

Did you ever wonder which Metrorail station is closest? Where’s the breakeven point between two stations? This map shows the areas you can actually reach within a half-mile walk along the roadway network, as we described previously. The twist this time is that I disallowed “overlap” within the GIS network analysis, so land is allotted to the closest station only, calculated by network walk distance.

What do you see in this map?  Here’s a regional view with all stations, as well.

Update 9/2/2014: the GIS source file for this map is now available for download, in geodatabase (.gdb) format.

Eight-Car Trains on Metro is Equivalent to Widening I-66 in Arlington by Two Lanes

July 14th, 2014 8 comments

Adding two extra cars to a six-car Metrorail train might not seem like much, but it is equivalent to widening I-66 through Arlington by two lanes. Plus, it’d likely be cheaper and faster for commuters, too.

Sometimes it’s hard to wrap one’s head around how just many people Metrorail can move. But where Metrorail operates in heavily congested corridors, seemingly small improvements can yield big results. In fact, matching the capacity of all eight-car trains system-wide would require 16-18 lanes of freeway into downtown, each way.

To match the capacity of eight-car trains on Metro, we’d have to widen I-66 in Arlington by at least two lanes. (Photo by wfyurasko, click for original)

In Arlington for instance, going to eight-car trains on the Orange Line as part of Metro 2025 is like widening I-66 by two lanes.  Let’s do the math:

  1. One lane of highway can move around 2,200 cars per hour, at its theoretical maximum.
  2. Today, every morning Metrorail runs about 18 trains per hour eastbound on the Orange Line through Arlington, and about a third are scheduled eight-car trains. That’s a train every three minutes, and equates to around 121 rail cars per hour, or 12,060 passengers per hour.
  3. By 2025 with eight-car trains, Metrorail will be able to run 21, eight-car trains per hour eastbound on the combined Orange and Silver Lines, which equates to 168 cars per hour.
  4. This means Metro 2025 will bring the line’s capacity to 16,800 riders per hour, or an increase of 4,740 passengers per hour.
  5. To accommodate 4,740 more people on I-66 at 2,200 cars per hour, 2 people per car, we’d need 4,740 / 2 / 2,200 = 1.1 highway lanes in each direction.

That means we’d need at least two new lanes on I-66 to match the capacity of Metro 2025. In addition, eight-car trains would be cheaper, and would likely move people faster through the corridor.

  • Eight-car trains on Metro would be over two times cheaper: the estimated cost to widen I-66 works out to about $3.50 per rush-hour trip over the life of the project, whereas Metro 2025 would be about $1.50.
  • Metrorail would likely move travelers faster than I-66 in the end.  Orange Line trains today normally run at around 35 miles per hour, while congested travel speeds on I-66 average around 18 miles per hour. While new highway lanes might move cars faster at first, the improvements would eventually be eroded by growing congestion.

Blue Line Riders Helped by Dedicated Signage

June 17th, 2014 7 comments

AlwaysShowBlueLinePIDSv2Some train arrival signs now always show the next Blue Line train, and it’s helping Blue Line riders determine their best route.

At rush times, Blue Line riders know they can sometimes see two or three Yellow or Orange Line trains go by before a Blue Line train arrives. For some riders, knowing just how far away the next Blue Line train is can help them decide: is it worth waiting, or should I get on the next train and transfer at L’Enfant Plaza?

To help Blue Line riders, Metro changed the arrival signs to always show the time until the next Blue Line train arrives, even if it’s more than three trains away.  That means that riders can always tell how far away a Blue Line train is, and decide whether to wait for it, or use the Yellow Line instead.

Fixing Core Stations in Metro 2025 Helps Riders from All Jurisdictions

June 12th, 2014 3 comments

Though many of the stations that Metro 2025 seeks to improve are in the District of Columbia, the capacity expansion would help riders from all jurisdictions.  

Metro needs to improve the capacity at over a dozen stations:  some of these stations are at capacity today, and our 100% eight-car train program will bring even more customers to already crowded stations.  We know we need to build new escalators, expand mezzanines, and build pedestrian passageways to meet this future demand.

The fact is that Metro 2025 is designed to benefit the Washington metropolitan area, residents of the District, Maryland and Virginia, as well as visitors from around the country and the world.

If you’re a commuter in Maryland or Virginia, it may look like the benefit of these improvements are focused on D.C. residents.   After all, 10 out of the 15 stations are located in the District of Columbia.  But the diagram below shows most of the riders who use these stations – those who create the need today, and who would benefit from fixing it – live in Maryland or Virginia.  In fact, 77% of the users of the Metro 2025 stations live in the suburbs.

 Three-quarters of riders benefiting from the station improvements in Metro 2025 live in Maryland and Virginia
