Examining the Relationship Between Speed Enforcement Laws and Traffic Safety

Principal Investigator:

  • Frank Douma, Director, SLPP, Humphrey School of Public Affairs

Project Summary:

This research will develop a taxonomy of the speed enforcement laws in Region 5 states and examine data regarding speed-related crashes and fatalities as corresponds to the resulting categories to determine if there are any relationships between enforcement regimes, public perception and awareness of speed enforcement laws, and resulting speed-related data. The hypothesis is that different enforcement regimes and variation in public perception and awareness of speed-related laws are at least confusing to users of the highway systems across the several states, and at worst make roads less safe in some states versus others. This work could lay the foundation for moving towards a more uniform, data-driven enforcement standard.
