DEVELOPING MODIFIED MUTCD STOP SIGN WARRANTS: THE CITY OF PORTLAND'S EXPERIENCE

In 1990, the City of Portland, Oregon began a study of the Manual on Uniform Traffic Control Devices (MUTCD) stop sign warrants. The purpose was to determine the adequacy of the application of the warrants in a large urbanized area with several thousand uncontrolled intersections. Because of this high number, uncontrolled intersections would be a reality in the city for many years. Upon completion of the study in 1991, several important findings were made, but most significantly, the City of portland chose to develop and implement modified stop signs warrants that reflected the findings. After nearly three years of applying the new warrants to stop sign installation investigations, Portland recently completed an analysis of the effects of the changed warrants. This paper focuses on the results of the initial study, and discusses the effects of the application of the modified stop sign warrants that were implemented by the City of Portland in 1992.
