CMF Most Wanted List
Although the field of highway safety research has progressed much in recent years, often there are safety strategies that are of interest to practitioners but which have not been covered well by research studies. The list below represents areas or specific countermeasures for which the CMF Clearinghouse does not have many quality CMFs. These areas have been shown to be of interest to users of the Clearinghouse based on search history and feedback through various webinars.
These items represent areas where crash-based safety evaluation research is needed — a CMF "Most Wanted" list.
- Driveway or access density near intersections
- Work zone traffic control devices
- School zone related countermeasures
- Pedestrian refuge areas
- Sharrows (shared lane markings)
- Split phasing
- Signal clearance intervals
- Signal head backplates
- LED signal heads
- Intersection skew
