EXPERIMENTAL STUDIES OF TRAFFIC SIGNS AND SIGNALS. PROCESSES AND PERFORMANCE OF VARIABLE TRAFFIC SIGNS

RECHERCHES EXPERIMENTALES SUR LA SIGNALISATION - PROCEDES ET PERFORMANCE DE LA SIGNALISATION VARIABLE

This document reviews all data available on variable traffic signs: their performance, mode of use and specific impact they can have on the road user. The various types of variable traffic sign (panel, rotating prism, continuous strip roller, flaps, optical fibre matrix) are described together with the characteristics of messages on variable panels. Results of tests on the day and night legibility of these signs are given. (TRRL)
