Annotation: An assessment was conducted on traffic speeds and volumes on the roads of the Clemson University campus.
Abstract: In assessing traffic speeds, the 85th percentile speed was chosen as the primary measure of speed. Historically, the 85th percentile operating speed has been used to set posted speed limits. For passenger vehicles, the safest group's 85th percentile speed ranged from 2 to 7 mph over the speed limit. This means that the least safe location in the safest group is minimally different from the safest location in the moderately safe group. For buses and commercial vehicles, the safest groups speed difference ranged from 3 to 13 mph over the speed limit. In addition, high traffic volumes were associated with slower speeds and vice versa. Overall, the locations with the lowest traffic volumes were found to have higher 85th percentile speeds above the posted speed limit. The results will be used in continuing initiatives to improve safety on Clemson University's campus and can be applied to other campus and municipality settings. Safety poses a concern on every college campus. However, little research information is available on transportation safety in university settings and how campus traffic is monitored and evaluated. In this study, Clemson University investigated traffic speed and volume on campus with data collected on specific road segments using Nu-Metrics NC-97 Highway Statistical Traffic Analysis Recorders in 2007.
