As early as 1924, the need for safety-knowledge was recognized. At a national conference on street and highway safety it was reported that safety data "are so vital to any comprehensive understanding and treatment of the safety problem that their collection and analysis in every State and community are essential" (Griffith, 2003). Many decades later, this simple statement has, in-fact, taken on increased significance. In the age of information, the challenge is now to make effective decisions based on a wealth of safety-related data. There is a growing recognition in the safety community that decisions are more effective if they are knowledge-based. Traffic records such as driver files, crash data, enforcement, highway traffic and geometric information, court records, and emergency medical records are the typical data needed to make effective safety-related decisions. Often these data are in various formats, maintained by distinct agencies, and require specialized knowledge to use and link together to achieve maximum use of the data. In their comprehensive review of the U.S. crash records systems, Delucia and Scoptaz (2005) made a number of recommendations for a successful, useful, robust traffic records system. One of those recommendations was that development of a "knowledge base" of traffic records information is imperative to fully extract the expense of creating the indivi
