Realistic Test of Hauer's Promising Site Identification Method.

摘要

The prevailing methods of identifying hazardous locations use the collision history of a system to find the locations where more collisions have occurred. Problems with these prevailing methods include the tremendous burden on agencies to maintain a full and accurate collision data set, the inability to assess the safety of new or changed sites, and the fact that cost-effective countermeasures may not be available for high-collision sites. In 1996, Dr. Ezra Hauer suggested the use of five criteria to find 'promising sites' with potential for productive countermeasure installation to address these problems. The objective of this research was to apply Hauer's ideas in a realistic test using an existing data set. Specifically the objectives include: Develop and apply a method by which Hauer's concepts can be applied, Identify problems encountered when applying this method, Identify possible solutions to problems encountered when applying this method, and Evaluate the feasibility of applying this method at the city level, county level, region level, and/or state level. Achieving these four objectives will provide engineers with insight on how to apply Hauer's concepts in their jurisdictions.
