Signs and signals

Public places such as cinemas, theatres, stores, supermarkets, etc., present a particular problem in an emergency. Staff should be trained in advising the public what to do should an alarm be sounded. The use of broadcast verbal warnings or safety instructions should be avoided since the message may be inaudible in some areas, can be misunderstood and give rise to confusion.

Punctuation marks do not exist, as one student recently complained, to make your life complicated. They are used to clarify your written thoughts so that the reader understands your meaning. Just as traffic signs and signals tell a driver to slow down, stop, or go, so punctuation is intended to guide the reader through your prose.

One of the first steps recommended in lEC 61508 is to determine the boundary of the Equipment Under Control (EUC) and the EUC control system. Since lEC 61508 is directed towards programmable electronics systems, it is natural to think of the road and its users as the EUC and the ITS as the control system. Under such a model, it is also natural to consider modelling hazards at the boundary of the control system, e.g. at the level of errors in the display of signs and signals.
