Skid Resistance Research Data
Description
Road sections within the boundaries of Amman, Jordan. Measurements of BPN and surface roughness. Historical Records of Traffic crashes . This research focuses on sites that are characterized as roadways with severe crash experience. They are mostly road sections with low skid resistance levels and pavement roughness. The skid resistance is measured in BPN and the pavement roughness in mm using a sand patch method. The crash statistics on these sections are obtained from the local traffic agencies including fatal and personal injury crashes. Crash severity index were calculated n terms of property damage only crashes per million vehicle- kilometers of travel. A prediction equation is derived using regression analysis to predict crash severity rates as a function of pavement roughness and skid resistance. Road maintenance agencies can predict severe crash experiences through periodic measurements of skid resistance and pavement roughness. The scheduling of corrective maintenance can be accomplished without running the risk of endangering the driving public. The prediction model can also be used to establish threshold values of BPN and surface roughness hat can be adopted by maintenance agencies to signal the need for immediate intervention.
