The effect of skid resistance and texture on crash risk

摘要: This paper presents the results of a first attempt to combine detailed information on road geometry (horizontal curvature, gradient and cross-fall), surface condition (roughness, rut depth, texture depth skid resistance), carriageway characteristics (region, urban/rural environment, traffic flow) crashes. Four subsets crashes were investigated: all reported injury fatal crashes; selected covering loss control events; occurring in wet conditions; conditions. One two-way tables Poisson regression modelling employed identify critical variables form their relationship with crash risk. Particular emphasis was placed quantifying effect resistance (a) For entry this conference, please see ITRD abstract no. E212865.
