THE USE OF MODULATED AND INTERRUPTED SIGNALS IN THE ROAD ENVIRONMENT
The current use of modulated and intermittent signals in the road situation is reviewed. The psycho-physical effects of "flashing" signals on the human visual system is discussed and is used to suggest an information code for "flashing" signals which encompasses and extends present practice. The immediate beneficiaries of such a code could be vulnerable road users--motorcyclists and bicyclists. Their over-representation in accidents having a major visibility component would be expected to be ameliorated by the enhanced conspicuity afforded them by a "flashing" light. Experimental work is required to investigate peripheral field and multiple source effects on conspicuity and conspicuity enhancement to ensure proper co-ordination in use of static hazard warning lights and vehicle-borne "flashing" light systems (a). The number of the covering abstract of the conference is TRIS no. 368448. (TRRL)
