WebThe drag factor on new concrete is 0.95, and the drag factor on polished concrete or asphalt is 0.75. A motorist who was involved in an accident claims he was driving at the posted speed limit of 60 miles per hour. A police officer measures the car's skid marks on the asphalt road to be 210 feet long. WebThis calculator use the well known formula S=√254*f*d It is clearly not a skid to stop “universal tool”, the calculator does not take into account any road condition as the correct interpretation of the road evidence (skid, scrub , scuff marks, yaw marks), slope, drag factor, wear rate of ice or snow on the road surface. If just “something else happens” …

WebApr 1, 2014 · The current research was completed to assess if the same formulae are also applicable to lower-friction surfaces, e.g. snow, ice. Test dummies were impacted by automobiles or launched from a ramp in order to simulate the airborne trajectory of a vehicle-pedestrian collision. Speeds were measured with a radar unit and/or the analysis … WebDrag factors were calculated using test speed, the measured skid distance, and the basic skid formula. The results for ABS and non-ABS vehicles were similar except for tests … downtown naperville holiday events
