The purpose of this study was to investigate in depth those intersections or locations within Iowa City where traffic congestion was increasing and the safety of motorists and pedestrians was becoming critical. A preliminary review of traffic volumes and accident records indicated that there were a total of eleven locations that should be studied in further detail. The proposed recommendations as submitted in this report are based on the criteria mentioned in the following paragraphs. In discussing the matter of traffic signal installations it is well to keep in mind the rationale that is followed in deciding as to whether or not signals are justified at a particular location.
