Speed is one of many factors that increase the risk of serious or fatal injury in traffic crashes. Understanding driver and road manager decisions regarding travel speeds is fundamental to improving traffic safety. The objective of this study was to test existing equipment and technology assets in monitoring driver decisions with regard to posted speed limits. Driver behaviors with regard to systematic and special traffic speed programs were considered. In cooperation with the state transportation agency, data were collected from a group of automatic traffic recorder sites (ATRs) for this effort. Analysis focused on speed metrics to quantify differentials relative to posted limit observed traffic speeds, and high-risk driver prevalence.
