| Run-off-road (ROR) crash records from a sample of 1946 km of Spanish two-lane rural roads were analyzed to study the effect of roadside conditions on safety. Four categorical indicators were used to characterize the main roadside features that have an influence on safety: alignment, roadside slope, obstacles offset and safety barrier disposition. Cluster analysis was used to group the 150 possible combinations of the four indicators in categories with homogeneous effects on ROR crash frequency and severity. As a result a five level Roadside Risk Index (RRI) was defined. The RRI facilitates the task of gathering homogeneous roadside safety related information and will be used in Spain as a variable in crash prediction modelling and as a reference for roadside improvement planning. | |
