CONSTRUCTION ZONE SAFETY: TAILOR-MADE GUIDANCE

ENCROACHMENTS INTO THE TRAVELED WAY OF CITY STREETS REQUIRE CONSIDERATION FOR SPECIAL CONSTRUCTION WARNING SIGNS OR DEVICES TO GUIDE TRAFFIC SAFELY AND EFFECTIVELY THROUGH THE CONSTRUCTION ZONE AND TO PROVIDE THE NECESSARY PROTECTION FOR THE WORKMEN. SOME CONSIDERATIONS IN THE SELECTION OF APPROPRIATE WARNING DEVICES AND CONTROLS ARE: TRAFFIC VOLUMES AND PATTERNS INCLUDING PEDESTRIAN REQUIREMENTS, PREVAILING SPEEDS, SAFE SPEED, DURATION OF CONSTRUCTION, AND VISIBILITY. THESE FACTORS MUST BE APPLIED TO THE BASIC ELEMENTS WHICH MAKE UP A PROPER CONSTRUCTION ZONE: (1) ADVANCE WARNING, (2) ALIGNMENT, (3) SEGREGATED WORK AREA, (4) ADEQUATE CAPACITY, (5) MAINTENANCE TO LOCATE WARNING DEVICES PROPERLY, (6) MAINTENANCE TO CHECK THE CONDITION OF WARNING DEVICES, AND (7) MAINTENANCE OF THE DETOUR ROADWAY WHICH MUST BE KEPT CLEAN AND FREE FROM MUD, DUST, AND DEBRIS.
