Author reflections on the human factors of transport signs.

In a contributor book of this kind, it is clear that multiple perspectives on the topic will emerge. This paper makes no apologies for this and instead argues that it is a strength, in part due to the richness of the work in this area. This final paper is therefore intended to be "democratic" by allowing all of the authors of the book to write a paragraph or two about how they approached their topics. The authors' reflections are presented in order of their contributions to the book. Only minimal editorial changes have been made to their words.
