This report will be of special interest to state, county, and city traffic engineers having responsibility for installing traffic signals. Governmental agencies and national committees (e.g., the National Advisory Committee on Uniform Traffic Control Devices) that develop signal warrants will also be interested in the research findings. A new peak-hour traffic signal warrant is proposed for use at locations having heavy traffic flows of short duration (e.g., an industrial plant exit). The basis for the proposed warrant includes (1) a comparative evaluation of previously suggested peak-hour warrants, (2) traffic characteristics data collected at over 200 intersections, and (3) engineering judgment regarding the perceived need for a signal.
