Crash Rates At Intersections, Eric R. Green, Kenneth R. Agent
Kentucky Transportation Center Research Report
The objectives of this study were to develop a database of intersections, match traffic crashes to these intersections, calculate crash rates for various types of intersections, and identify intersections with the highest crash rates. A procedure was used to: a) identify intersections, b) assign crashes to these intersections, c) determine entering traffic volume, d) calculate a crash rate for each intersection, and e) calculate a critical rate factor (CRF) for each intersection.
About 7,000 intersections were identified with almost 19,000 crashes related to these intersections for the three-year period of 2000 through 2002. The analysis identified 428 intersections that had …

Highway Crash Site Management, Monica L. Barrett, Jennifer R. Walton
Kentucky Transportation Center Research Report
Traveler delay is the problem most often associated with highway crashes, but by far the most serious problem is the resulting secondary crashes that occur. Another related issue is the danger posed to response personnel serving the public at the scene of a crash. The longer a crash is in place, the longer the responders are vulnerable and exposed to injury.
The Kentucky Transportation Center, in cooperation with the Kentucky Transportation Cabinet, developed a checklist and interagency workshop to address ways to secure and coordinate the resources necessary to restore the roadway’s operation in a safe and timely manner. The …
Traffic Control At Stop Sign Approaches, Kenneth R. Agent
Traffic Control At Stop Sign Approaches, Kenneth R. Agent
Kentucky Transportation Center Research Report
The objectives of this report were to: a) determine the number of crashes in Kentucky involving a driver disregarding a stop sign and the locations where these occur, b) determine the characteristics of these crashes, c) investigate loca tions with a large number of this type of crash, and d) make recommendations to reduce the probability of a driver disregarding a stop sign. The majority of the analyses involved a review and analysis of crashes where a stop sign was listed as the traffic control and “disregarding the tra ffic control” was listed as a contributing factor. Intersections having a …
