About the research

This research involves a detailed study of speed-related trends on rural Iowa interstates, as well as on the high-speed non-freeway system including two-lane and multilane highways. This study will specifically examine current trends in travel speeds, as well as traffic crashes, injuries, and fatalities over time. Finally, the economic impacts associated with increasing speed limits on rural interstates will be assessed.
