Between 2017 and 2020, I wrote nearly twenty articles for the D.C. Policy Center, a Washington, DC think tank focused on urban issues in the Washington, DC region. These articles covered a number of topics, including Metrorail’s service cuts and ridership issues in 2017-2018, proposals for improved suburb-to-suburb transit in the DC region, and the demographic history of the region.

Metrorail Cuts and Ridership Issues, 2017–2018
Between March and May 2017, I wrote a series of five articles for the D.C. Policy Center on WMATA‘s Metrorail service cuts and fare increases, comparing Metrorail’s fares and service to those on other US rapid transit systems, as well as DC commuter rail fares to fares on other US commuter rail systems. These were followed by an article in February 2018 on how the Metrorail service and funding crisis had led to Metrorail no longer being the second-busiest rapid transit system in the United States.
Note: Several of these articles were republished by Greater Greater Washington.

Suburb-to-Suburb Transit in the DC Region
In February and March 2019, I wrote a seven-article series for the D.C. Policy Center making extensive proposals for circumferential transit in the DC area, including Purple Line extensions to Tysons Corner and Largo and a number of bus rapid transit lines. My analyses included estimates of construction cost for the Purple Line extensions and maps of activity density along the proposed routes, and I discussed both projects currently in the planning phase—largely bus rapid transit lines in Northern Virginia—and projects that I think deserve more serious consideration than they have so far.

- “For circumferential transit in the District, try crosstown bus lanes,” by DW Rowlands, D.C. Policy Center, (19 March 2019).
This article series caught the interest of the Washington Metropolitan Area Transit Authority (WMATA) Board, and I was invited to give a ten-minute presentation to the board on the Washington, DC region’s need for circumferential transit. The slides from my presentation are available online here.
Demographic History of the Region, 1970–2020
Between July 2019 and January 2020, I wrote a series of four articles for the D.C. Policy Center with maps of population density and race, income, and education demographics in the DC area from 1970 to present, based on data from the National Historical GIS Database. I hope to eventually extend this analysis back to 1860 or earlier by hand-entering data from Census reports into minor civil division geometries derived from old maps. However, this will be a major undertaking and I have no estimate of when I will be able to complete it.

Dark purple indicates a density of 1.5-7.5 people per acre.
Light purple a density of 7.5-15 people per acre.
Orange indicates a density of 15-30 people per acre.
Yellow indicates a density of >30 people per acre.
