ACCIDENT RELATIONSHIPS OF ROADWAY WIDTH ON LOW-VOLUME ROADS

Open publisher page 48 citations

Abstract

An analysis was performed to quantify the accident effects of lane and shoulder widths on rural roads carrying fewer than 2,000 vehicles per day. The primary data base used in the research contained accident and roadway characteristic information for more than 6600 km (4,100 mi) of two-lane roadway sections in seven states. Independent data bases from three states (Minnesota, Illinois, and North Carolina) for roadways totaling more than 86 000 km (54,000 mi) were selected to validate the accident relationships found in the primary data base. Analysis of covariance was used to quantify accident relationships on these low-volume roads. Single-vehicle and opposite-direction accidents were classified as related accidents because the accident rates for these two types were found to be related to differences in lane and
