The Federal Highway Administration has a full and open requirement to: Investigate the feasibility of using a variety of traditional and non-traditional information resources in order to increase our understanding of crash causation on two-lane rural highways. Virtually all of the readily available information about roadway crashes is based on the information typically coded in police crash reports. Geographic Information System (GIS) technologies now allow access to a great deal of information that was previously unavailable. The collection and analysis of this information may help lead us to a better understanding of the "who, what, where, when, why and how" of crashes. To test the feasibility of using the various data sets, this project will focus on investigating the causative, precipitating, and predisposing factors in crashes. The methodologies being developed should also be applicable in examining other crash scenarios. The resulting contract will require extensive, relevant knowledge and experience in areas such as: the extraction and interpretation of data sets such as; NHTSA, CIREN, FARS, NASS, CDC, NMVCSS, FHWA, HSIS and any other data sets that might inform this study; roadway safety countermeasures; research and analysis; roadway safety design measures; State level safety and speed management programs; application of MUTCD provisions on traffic control signs; and roadway geometric design.
