Safety Evaluation of the 13 Controlling Criteria for Design

The objectives of the research are to (1) compile what has been learned about the relationship of the 13 controlling criteria to safety; (2) identify key knowledge gaps and conduct research to fill those gaps; (3) based on safety knowledge, recommend whether changes are needed in the list of design elements that are considered as controlling criteria; and (4) recommend whether the list of design elements considered as controlling criteria should vary between roadway types. The tasks that should be undertaken in the research are as follows: (1) Review safety research literature to establish what is known about the relationships of the 13 controlling criteria to safety. This review should include safety research results assembled for the forthcoming AASHTO Highway Safety Manual; (2) with the exception of structural capacity and vertical clearance, determine which of the 13 controlling criteria have safety effects that are well understood; (3) for any of the 13 controlling criteria with safety effects that are not well understood, formulate research plans to determine those safety effects; this could potentially include investigations of bridge width, vertical alignment, cross slope, and/or horizontal clearance; (4) execute the research plans developed above; and (5) based on the safety information in the literature and the research results, recommend whether changes are needed in the list of design elements that are considered as controlling criteria and whether the list of design elements considered as controlling criteria should vary between roadway types.
