Alternative Sign Sequences for Work Zones on Rural Highways
Two experiments were done on a two-lane rural road (US-2) in central Maine to evaluate the effectiveness of alternate signing sequences for providing warning to motorists of construction and … [Read more...] about Alternative Sign Sequences for Work Zones on Rural Highways
Field Evaluation of Highway Advisory Radio for Traffic Management in Work Zones (abridgement)
Studies were conducted at a major maintenance work zone on a rural Interstate highway in Texas to evaluate the use of Highway Advisory Radio (HAR) for traffic management in work zones. The studies … [Read more...] about Field Evaluation of Highway Advisory Radio for Traffic Management in Work Zones (abridgement)
Accident Characteristics Before, During, and After Safety Upgrading Projects on Ohio’s Rural Interstate System
In 1973, minor safety upgrading projects were conducted at 21 locations on the rural Interstate system of Ohio, involving 618 km (384 miles) of freeways. In 1972, the accident rate per million vehicle … [Read more...] about Accident Characteristics Before, During, and After Safety Upgrading Projects on Ohio’s Rural Interstate System
