SOME PRINCIPLES FOR COMMUNICATING WITH DRIVERS THROUGH THE USE OF VARIABLE-MESSAGE DISPLAYS

BEFORE PRINCIPLES, RULES, OR TENETS CAN BE DEVELOPED, THE EXPECTATIONS OF MOTORISTS NEED TO BE DETERMINED. IT MUST BE ASSERTAINED WHETHER MOTORISTS HAVE LEARNED THE MESSAGE CONTENT OF SIGNS AND RESPONDED WITH APPROPRIATE BEHAVIOR. ACCORDING TO THE STUDIES CITED AND CURRENT RESEARCH, MOTORISTS TEND TO DISREGARD THE SIGNS IF THE SIGNS IF THE SIGNED INFORMATION BLENDS INTO THE BACKGROUND AND IF THE REGULATIONS OF CERTAIN TRAFFIC MOVEMENTS ARE IN CONFLICT WITH PERCEIVED TIME SAVINGS, RESPECTIVELY, A BRIEF DISCUSSION FOLLOWS ON (1) INTERPRETATION - STRESSES CONTINUITY OF EXISTING INFORMATION; (2) RELATABILITY - REFERS TO SIGNED REFERENCE TO THE ACTUAL GEOMETRIC AND TRAFFIC CONDITIONS, INCLUDING THE MAP REPRESENTATION OF SUCH CONDITIONS; (3) ADVANCE NOTICE - REFERS TO THE PLACEMENT OF DISPLAYS IN RELATION TO THE TOTAL ENVIRONMENT; AND (4) PROMINENCE - CONCERNS SIGHT DISTANCE LIMITATIONS.
