| dc.description.abstract | The Road Impact Factor is a measure of ride-quality. It is derived from the average inertial
response of vehicles to road roughness. Unlike the International Roughness Index, the most
common measure, the road impact factor does not rely on specialized instrumentation to measure
spatial deviations from a flat profile. The most significant advantage of the Road Impact Factor
is that low-cost sensors distributed in smartphones and connected vehicles generate the
measurements directly. Standardizing the sample rate of inertial sensors in vehicles will provide
consistent measures at any speed. This study characterizes the impact of sample rate and
traversal volume on measurement consistency, and conducts case studies to validate the theories
developed for a recommended standard at 64 hertz. | en_US |
