L’Enfant Plaza Station Capacity Improvements Study

December 6th, 2012 No comments

The L’Enfant Plaza Station is one of busiest stations in the Metrorail system and handles thousands of passenger transfers on four of the five Metrorail lines.  It ranks third among all stations in absolute ridership growth over the last five years.

Earlier this year, Metro initiated a station capacity improvements study, similar to previous studies that evaluated the feasibility of station access and capacity improvements and station circulation enhancements at Gallery Pl-Chinatown and Union Stations.  The purpose of this study is to identify and address the physical and operational internal capacity constraints of L’Enfant Plaza Station.  Both short-term and long-term capacity enhancement solutions will be sought with operational improvements and constructability in mind.

Current and Future “Hot-Spots” at L’Enfant Plaza Station Platforms during the AM Peak

In order to assess the current and future conditions within L’Enfant station, Metro has used a pedestrian simulation tool that enables the quantification of crowded conditions.  The maps included here show existing and future condition profiles of the upper and lower level platforms within the station.  Future conditions were estimated using MWCOG/TPB travel demand model, Metrorail ridership growth forecasts and Metro origin-destination data sources.  Cumulative mean density maps help to identify “hot-spots” within the station – areas where high levels of crowding are sustained.

Analysis of current pedestrian activity during the AM peak 15-minute interval showed that the station currently operates at safe levels on both platforms in the morning peak hour, and identified a large volume of transfers between the northbound upper platform where Green and Yellow lines run and the westbound lower platform where Orange and Blue lines operate.   By year 2030, however, these conditions are expected to worsen with growth of transfers.  The levels of crowding in the transfer areas leading to the lower platform intensify due to increased passenger flows and space restrictions adjacent to escalators.  Also, high passenger densities are shown to occur at the westbound Orange and Blue platform during the morning rush hours.

A reversed pattern of crowding is shown between the eastbound lower platform and the southbound upper platform for the returning passengers during the PM peak 15-minute interval.  As expected, conditions worsen with increased passenger flows and transfer activity forecast for 2030 on the southbound upper platform.

Given the existing and future “no-build” scenarios presented here, Metro is currently working to develop short and long-term design alternatives for detailed evaluation.  Stay posted for additional simulation and conceptual design results as they become available.

New Pedestrian Paths at College Park Station

June 6th, 2012 3 comments

In conjunction with the Bike & Ride facility, Metro recently constructed multiple sidewalks on the east side of College Park – U of MD station to provide easier and safer pedestrian and bicycle access to the station and the Bike & Ride.  One of the sidewalks provides direct access to Paint Branch Parkway which leads to the Northeast Branch Trail less than ½ mile away.  In addition to the sidewalks, we installed curb ramps to meet ADA standards, and established a safer pedestrian route across the bus loop to the station entrance.

We undertook this work as part of Metro’s Pedestrian and Bicycle Element of 2012-2017 Capital Improvement Program.  We will be making bike, pedestrian, ADA and sidewalk improvements next at Cheverly, Landover, New Carrollton, Glenmont, Shady Grove, Brookland-CUA, Huntington, W. Falls Church, Vienna and Van Dorn.  What key bike and pedestrian connections at stations do you recommend be made?

Gallery Pl-Chinatown Capacity Improvements Study Underway

September 22nd, 2011 13 comments

Ridership growth at the Gallery Place-Chinatown Metrorail station from 1977 – 2011.

The Gallery Pl-Chinatown Station is the third-busiest station in the Metrorail system, with an average of 26,000 daily passenger boardings in May 2011.  Combined with the Metro Center Station less than 1,000 feet away, these two stations facilitate downtown transfers on all five Metrorail lines, with the Yellow, Green and Red Lines at Gallery Place and the Orange, Blue and Red Lines at Metro Center. The Gallery Place Station consists of two side platforms that serve the Red Line on the upper level and one center platform that serves the Green and Yellow Lines on the lower level.

Redevelopment in the station area catalyzed by the opening of the Verizon Center in late 1997 has drastically increased the demand at this station, resulting in crowded conditions during the peak travel times throughout the station, including mezzanines, platforms and escalators.  Weekday ridership has increased from an average of 6,500 boardings in 1997 to an average of 26,000 in 2011. Although ridership has stabilized over the past few years, more growth is expected in the near future with new CityCenterDC development currently under construction at the old convention center site at 10th Street and H Street NW.

Metro’s planners are currently undertaking the Gallery Place Station Access and Capacity Improvement study, with the purpose of identifying capacity constraints and developing improvement alternatives at the station.  Similar to the Union Station Access Study, this study will provide simulations of the projected pedestrian environment on the platform at key milestone years, and will measure the effectiveness of the proposed capacity improvements.

Union Station Metrorail Access and Capacity Study

Animation of existing conditions, partial build and full build scenarios

In October, we published a post about the ongoing Union Station Metrorail Access and Capacity Study, and included a pedestrian simulation showing the existing conditions at the Union Station Metrorail station’s north mezzanine.  The study has been completed, and the proposed access and capacity improvements and resultant station performance are described below

Currently, passengers traveling through the north mezzanine experience congestion on a daily basis.   Imagine what would happen at the north mezzanine in the next 20 years, once Union Station’s local and intercity travel facilities have been expanded (including the planned streetcar terminating at 1st and H Streets NE) and the millions of square feet of planned development in the surrounding areas have been completed. Our analysis shows that pedestrian volume through the north mezzanine will increase by 60%.

The biggest challenge faced by Metro during this study was to identify feasible improvements that would provide enough capacity for all users while ensuring compatibility with building functions and historical characteristics.  Metro worked with DDOT and Union Station stakeholders to develop two improvement alternatives: Partial Build and Full Build.  These alternatives are illustrated in the animated graphic below, which rotates between existing conditions, partial build and full build every 15 seconds.

RTSP Rail Enhancement Strategy: Interline Connections and Station Improvements

February 16th, 2011 7 comments

The purpose of this strategy is to allow different rail lines to operate on the same track.  This type of operation can help reduce capacity constraint on some lines and provide new connections between existing Metrorail lines.

The four interline connections proposed include:

1) Connect Orange and Blue at Rosslyn
2) Connect Yellow and Blue at Pentagon
3) Connect Yellow and Green near L’Enfant Plaza
4) Connect Orange and Silver near West Falls Church

Some benefits of these interline connections include:

  1. Orange/Silver-Blue inter-lining south of Rosslyn to allow a Silver Line running between the two airports
    1. BENEFIT: Faster trip to Ballston, Tysons and airports within Virginia
  2. Blue-Yellow inter-lining north of Pentagon to allow I-66 corridor rail lines going through 14th Street Bridge
    1. BENEFIT: Utilize throughput capacity on 14th Street Bridge
  3. Yellow-Green inter-lining south of L’Enfant Plaza to allow a Yellow Line split to Anacostia/Navy Yard
    1. BENEFIT:  Allow direct access between Anacostia and southern Maryland to job sites in southern Arlington and the City of Alexandria.

Additionally, this strategy will explore the benefits of making improvements to several of the system’s core stations:

  1. Pedestrian tunnel between Farragut North and Farragut West;
  2. Pedestrian tunnel between Metro Center and Gallery Place;
  3. Increase amount of vertical capacity at Union Station;
  4. Increase transfer capacity at the three core transfer stations:  Metro Center, Gallery Place and L’Enfant Plaza

Embedded sensor, currently being tested at Fort Totten Kiss and Ride metered parking spaces.

One of the challenges Metro faces is how to best support Parking customers. Good data on parking space utilization at metered Kiss and Ride spaces can be hard to come by and finding a metered parking space at many stations can involve guesswork. To address this lack of space availability information, Metro is beginning a 1-year pilot of sensors in parking spaces at the Fort Totten Metro Kiss and Ride parking lot to capture data on space availability and usage and to facilitate payment. These battery-powered sensors will be mounted flush with the pavement in each parking space, and communicate information on availability and usage. These space sensors will last 5-7 years on their internal batteries, and provide nearly real-time information. Read more…

Union Station Simulation

October 19th, 2010 3 comments

The Metrorail Station at Union Station is the busiest station in the Metrorail system, with 70,000 passengers entering and exiting daily.  This station has experienced substantial ridership growth in the past three decades from the development of surrounding DC neighborhoods, expanded intercity travel and commuter rail’s growing popularity.  The existing station, designed in the 70s, can no longer accommodate the current and future passenger travel.   Passengers experience congestion on a daily basis.

In late 2009, Metro, in collaboration with the District Department of Transportation (DDOT), initiated a Union Station Capacity and Access Improvements Study.   The objective is to assess capacity deficiencies and develop alternatives to enhance pedestrian access, increase station capacity, reduce travel time and improve connectivity to the other transportation modes.  To be able to compare the benefits of the proposed alternatives, Metro used a pedestrian simulation tool, developed by Legion, to quantify and assess the performance throughout the station’s north mezzanine under the current station conditions and with the proposed capacity improvements.  We’ve put this post up so people can see the kinds of analysis tools Metro is using to evaluate station capacity and to visualize capacity and operating issues.  Metro will be using the pedestrian simulation tool and analysis at other stations experiencing crowded conditions, such as the Gallery Place-Chinatown station.
