Continued suggestions from the public resulted in VIC ROADS syndicate trial of means of increasing driver awareness that they had entered a reduced speed zone. This report documents a subsequent, more extensive trial of rumble alerting strips, pavement numerals and yellow versus white longitudinal lining (edge, lane and centre lines) as individual and combined devices to increase driver awareness of the change in speed zoning. The results show the total "WHITE ZONE' treatment is more effective than the total 'YELLOW ZONE' treatment. Pavement numerals had a minimal value in reducing vehicle speeds. Rumble alerting strips of 12 mm height were effective in reducing vehicle speeds at distances of 200 to 700 metres after the start of the reduced speed zone, however, the reduction of speeds is not considered sufficient to justify widespread installation.
