These include papers published in refereed journals, book chapters, conference papers, and preprints intended for publication.
The academic publishing dinosaurs are still clinging to an obsolete model of dissemination, grabbing copyright of scientific work and charging extortionate fees for access to it. If you are having difficulties obtaining a final published version of any manuscript (e.g. to cite the correct page numbers for quotes) then email me for suggestions.
Papers in red are submitted manuscripts that are subject to change. They should not be cited without checking with me first. Papers in blue are accepted manuscripts that are ready for publication. There may be minor proofing corrections, and full citation information (volume number, page numbers) will be added as soon as known. Papers in black have been finalised and are not subject to change.

Conference state-of-the-art paper. An international multidisciplinary collaboration that discusses the state of the art of transit map research, looking at design, computer automation and human (usability testing) approaches, common ground between the three and future research challenges.
Roberts, M.J. (2019). The Decade of Diagrams. Schematic Mapping Workshop 2019, TU Wien, April.
Workshop position paper. A survey of the unprecedented burst of schematised network maps during the 1930s, arguing that their shear quantity and diversity could just as likely result from the forces of modernism sweeping the world, as the Anglocentric view that designers discovered schematision techniques via Beck’s London design.
Roberts, M.J. (2019). Us versus them: Ensuring practical and psychological utility of measurements of schematic map usability. Schematic Mapping Workshop 2019, TU Wien, April.
Workshop position paper. Discusses the various ways of objectively measuring usability, their utility and underlying assumptions, and the importance of reconciling these with user ratings and preferences. New ways of measuring usability that might bridge the divide are described.

Preprint of refereed journal paper. My large-scale internet survey of opinions on usability and design is now published, along with related experiments looking at Paris Metro and Berlin U-Bahn maps. The findings on intuitive theories of design are particularly interesting.

Lucas & D. Over (eds.), The thinking mind: A festschrift for Ken Manktelow (pp. 178-190). Hove, UK: Psychology Press.
Preprint of book chapter. A review of psychological findings on reasoning and intelligence that are relevant to theories of effective schematic map design.

Preprint of refereed journal paper. The first usability test conducted on a concentric circles map. In terms of journey planning, this design performed poorly, but this study also develops the journey planning methodology further, and provides some important insights into the relationship between subjective opinions on usability, and objective measurements of this.

A Docklands Light Railway study. Transportation Research A, 94, 446-460.
Preprint of refereed journal paper. A large-scale usability study of several Docklands Light Railway prototype train maps. This used a touch-screen methodology and there were several important findings concerning usability ratings, task accuracy, and journey choices influenced by map configuration.

Refereed conference paper. This paper reports research comparing the usability of two maps
from a large-scale internet rating study. Of these, the map with the worse ratings yielded
the better planning performance!
Roberts, M.J. (2014). What’s your theory of effective schematic map design? Schematic Mapping Workshop 2014, University of Essex, April.
Workshop position paper. A discussion of the importance of lay-theories of design in determining people’s evaluation and creation of schematic maps. This also includes a preliminary analysis of my internet survey of usability and aesthetic ratings of nine alternative London Underground maps, and an overview of various prescriptions, theories, and frameworks for effective design.
Roberts, M.J. (2014). Schematic maps in the laboratory. Schematic Mapping Workshop 2014, University of Essex, April.
Workshop position paper. A review of empirical work that investigated schematic map usability, and some of the difficulties that must be overcome in conducting such research.

Preprint of refereed journal paper. The curvilinear map was 50% faster for journey planning than the official octolinear map. Objective and subjective measures of usability were not correlated. The octolinearity = gold standard conjecture is refuted by these findings.
