Safety Analyst uses state-of-the-art statistical methodologies to identify roadway locations and safety improvements with the highest potential for reducing crashes. The software systems flags spot locations and road segments that have higher-than-predicted crash frequencies. It also flags locations for review based on crash severity. This methodology is more efficient and cost effective and will allow the department to study fewer locations yet address more crashes each year.

The lists this year are into rural and urban areas.  The urban system covers all streets, roads, and highways located within urban boundaries designated by the U.S. Census Bureau. The Bureau defines two types of urban areas based on population. Small urban areas are urban places with a population or 5,000 or more and not located within any urbanized area. An urbanized area is an area with a population of 50,000 or more. As might be expected, the rural functional classification system covers all other streets, roads, and highways that are not located within the boundaries of small urban and urbanized areas.

The descriptions of the emphasis areas are:

Rural Intersection Peak Searching Excess Locations
These locations were selected because they have a higher-than-predicted crash frequency for each intersection.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.

Rural Non-Freeway Peak Searching Excess Segment Locations
These locations were selected because they have a higher-than-predicted crash frequency for this roadway type.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.  Only crashes indicated on the OH-1 as being non-intersection crashes were included in this analysis.

Rural Freeway Peak Searching Excess Locations
These locations were selected because they have a higher-than-predicted crash frequency for this roadway type or interchange location.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.

Urban Intersection Peak Searching Excess Locations
These locations were selected because they have a higher-than-predicted fatal and injury crash frequency for each intersection.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.

Urban Non-Freeway Peak Searching Excess Segment Locations
These locations were selected because they have a higher-than-predicted fatal and injury crash frequency for this roadway type.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.  Only crashes indicated on the OH-1 as being non-intersection crashes were included in this analysis.

Urban Freeway Peak Searching Excess Locations
These locations were selected because they have a higher-than-predicted fatal and injury crash frequency for this roadway type or interchange location.  Approximately, the Top 50 locations will be studied.  The remainder of the locations listed have a higher-than-predicted frequency of crashes and can be used as a reference.

Protection of Data from Discovery & Admission into Evidence
Section 148(g)(4) stipulates that data compiled or collected for the preparation of safety lists “…shall not be subject to discovery or admitted into evidence in a Federal or State court proceeding or considered for other purposes in an action for damages arising from any occurrence at a location identified or addressed in such reports…” This information is also protected by 23 USC 409 (discovery and admission as evidence of certain reports and surveys).
