  • Traffic and Road Sign Recognition
    Traffic and Road Sign Recognition Hasan Fleyeh This thesis is submitted in fulfilment of the requirements of Napier University for the degree of Doctor of Philosophy July 2008 Abstract This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm. Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%.

  • The Public Debate on Jock Kinneir's Road Sign Alphabet
    Ole Lund The public debate on Jock Kinneir’s road sign alphabet Prelude There has been some recent interest In August 1961 two researchers at the Road Research Laboratory in in Jock Kinneir and Margaret Britain published a paper on the ‘Relative effectiveness of some letter Calvert’s influential traffic signs types designed for use on road traffic signs’ (Christie and Rutley and accompanying letterforms for 1961b). It appeared in the journal Roads and Road Construction. A Britain’s national roads from the late shorter version was published in the same month (Christie and 1950s and early 1960s.

  • (Mostly) True Story of Helvetica and the New York City Subway by Paul Shaw November 18, 2008
    FROM VOICE ~ TOPICS: branding/identity, history, signage, typography The (Mostly) True Story of Helvetica and the New York City Subway by Paul Shaw November 18, 2008 here is a commonly held belief that Helvetica is the signage typeface of the New York City subway system, a belief reinforced by Helvetica, Gary Hustwit’s popular 2007 documentary T about the typeface. But it is not true—or rather, it is only somewhat true. Helvetica is the official typeface of the MTA today, but it was not the typeface specified by Unimark International when it created a new signage system at the end of the 1960s. Why was Helvetica not chosen originally? What was chosen in its place? Why is Helvetica used now, and when did the changeover occur? To answer those questions this essay explores several important histories: of the New York City subway system, transportation signage in the 1960s, Unimark International and, of course, Helvetica. These four strands are woven together, over nine pages, to tell a story that ultimately transcends the simple issue of Helvetica and the subway. The Labyrinth As any New Yorker—or visitor to the city—knows, the subway system is a labyrinth. This is because it is an amalgamation of three separate systems, two of which incorporated earlier urban railway lines. The current New York subway system was formed in 1940 when the IRT (Interborough Rapid Transit), the BMT (Brooklyn-Manhattan Transit) and the IND (Independent) lines were merged. The IRT lines date to 1904; the BMT lines to 1908 (when it was the BRT, or Brooklyn Rapid Transit); and the IND to 1932.
