Nationally accepted traffic signal warrants are provided in the Manual on Uniform Traffic Control Devices (MUTCD). There are 11 warrants recommended in the MUTCD; four of these are vehicular volume related warrants. These warrants are: Warrant No. 1 - Minimum Vehicular Volume; Warrant No. 2 - Interruption of Continuous Traffic; Warrant No. 9 - Four Hour Volume; and Warrant No. 11 - Peak Hour Volume. In all four of these warrants the minor street minimum hourly volume is defined. The volume is the total volume of right turn, through, and left turn movements from the minor street approach. The study: (1) developed a state-of-the-art report on the topic of 'Effect of Right Turning Vehicles on Traffic Signal Volume Warrants'; (2) recommended that further research be done leading to the development of guidelines for excluding or including right turning vehicles in the total approach volume for evaluation of the need for a traffic signal; and (3) developed a research work plan for the future.
