This study examines two candidate peak-hour traffic signal warrant criteria. One was suggested by the Signals Subcommittee of the National Advisory Committee on Uniform Traffic Control Devices, referred to as the NAC Warrant. The other was developed as a part of NCHRP Project 3-20 and is noted as the NCHRP warrant. The peak-hour warrant would typically be applied at intersections in the proximity of large industrial parking lots or office complexes to determine whether traffic signals should be installed. The new warrant is based on field measures of queue length. Simply stated, a signal is warranted when there is an average queue of at least 4 vehicles for 1 hour of a typical day.
