History and Design of Transit Maps
I have been researching the history and design of the New York City subway maps for a number of years. In 2012 I published the book Vignelli: Transit Maps based on interviews with Massimo Vignelli, Joan Charysyn, and others, as well as archival research. I am preparing several further volumes documenting the hstory of the NYC subway map since its inception.
In 2017-2018 I was doing experimental research at the Universiy of Kent at Canterbury. See 'Effect of colour-coding on Usability' below.
History of the New York City subway map
Chapters, articles, and papers
- Vignelli: Transit Maps (RIT Press, 2012)
This is the first book-length treatment of Massimo Vignelli's contribution to transit maps, focusing chiefly on his 1972 diagrammatic map of the New York City subway system, but also including his prototypes for the Washington Metro and his contribution to the Paris RER map.

History & design: Symposium
An evening symposium that I organised on October 27, 2015. This was generously hosted by Cooper Union, who also recorded it on video. The event was timed to the 111th anniversary of the opening of the New York City subway on October 27, 1904, and looks at the recent past of the subway and its possible future. The following are video segments recorded by Cooper Union.
David Greenstein introduces the evening on behalf of Cooper Union, and Peter B. Lloyd introduces some basic concepts of the mapping of the New York City subway.
- R. Raleigh D'Adamo: presentation
R. Raleigh D'Adamo on how he created his 1964 map, which introduced color-coding to the New York City subway map.
- Peter B. Lloyd: Presentation
Peter B. Lloyd on the development of the New York City subway map after Raleigh D'Adamo's introduction of color coding in 1964.
- John Tauranac: presentation
John Tauranac (Chair of the 1970s Subway Map Committee) on how to fix the subway map.
- Eddie Jabbour: Intro and Presentation
Eddie Jabbour presents the KickMap family of subway maps.
