A recent SURTC study evaluates the significance of transit ride quality. This study developed a low-cost smartphone-based method and associated data transformations to characterize ride quality. The method distinguished between vibrations induced from road unevenness and operator behavior. The authors validated the accuracy of the method by conducting surveys to characterize the perceived roughness intensities from buses traveling routes of distinctly different roughness levels. The surveys found that smooth rides mattered to most passengers, and that rough rides could even lead to some loss of ridership. Click on the link below to see the full report:
