Abstract

In recent years local jurisdictions have successfully converted unwarranted multiway stop-controlled intersections to less restrictive forms of control. However, there is wide variation in the approaches used and factors considered in the conversion decision. Therefore, FHWA initiated a national study of the processes, with two primary objectives: (a) to develop and test procedures to convert multiway stop-sign-controlled intersections to two-way stop-sign-controlled intersections, and (b) to document the safety effects of converting multiway stop controls to two-way controls. In this paper the study is summarized and the results are presented in the form of recommended conversion procedures. Thirty separate geographically distributed jurisdictions were visited and information and data regarding the various conversion experiences were collected. Data from more than 170 separate intersections were studied by the research team in arriving at the conclusions and recommended procedures in this paper. Laboratory driver preference studies were conducted to determine the most suitable warning and information signs. In addition to local government officials, several consultants as well as professionals in quasi-public agencies were interviewed and their experiences and knowledge of the conversion process were incorporated, where appropriate. The emphasis of the study has been on the safety aspects of the conversion process.
