Pennsylvania Quality GuidelinesAbstract:
ATSSA’s Pennsylvania Quality Guidelines booklet helps contractors and agency personnel judge when a traffic control device has outlived its usefulness. Color photos and written descriptions of work zone devices in a convenient, pocket-sized format illustrate three levels of device condition: acceptable, marginal, and unacceptable. Devices described include signs, barricades, drums, cones, tubes, warning lights, arrow displays, portable changeable message signs, pavement markings, and markers. A sample specification is included to assist agencies that want to formally adopt the standard.
