Abstract

Run-Off-the-Road crashes (including: overturning, outgoing or fixed object crashes) form a considerable part of all rural road crashes and delineation generally affects them. This study aims at evaluating longitudinal delineation using pavement markings and its combination with the road pavement raised markers in the reduction of rural road crashes. Thereafter, the crash modification factor (CMF) will be found applying the before-after study on several treatment sites. In order to, traffic and crash data and the other required data for evaluating with empirical Bayes method gathered in Khorasan Razavi province in year 2014 as the treatment year for delineation activities.
