Description
Abstract:	Widespread application of any type of centerline buffer in Texas has been limited, so this technical brief shares the expected safety effects associated with this countermeasure. National Cooperative Highway Research Program (NCHRP) Project 17-66 documents the safety effects of centerline buffers on opposite direction (OD) crashes on rural Texas highways. For the analysis, researchers identified seven two-lane highway sites treated with wide centerline buffets (between 4 and 12 ft.] and 56 untreated comparison sites. Analysis results indicated that the centerline buffer had a positive effect on reducing OD crashes on two-lane highways, with a coefficient statistically significant at the 15 percent level.
