Condition B, the interruption of continuous traffic warrant, is "intended for application where the traffic volume on a major street is so heavy that traffic on a minor street suffers excessive delay or conflict in entering of crossing the major street." Traffic control signals could be considered if hourly vehicular volumes exceed the following standards for each of any eight hours of an average day: o Major street- 750 vph total on both approaches, o Minor street- 75 vph on only the high volume approach for the same eight hours. Warrant 2, the four hour vehicular warrant, is "intended to be applied where the volume of intersecting traffic is the principal reason to consider installing a traffic control signal." The standard includes a graph with major street hourly volumes (total of both approaches) on the horizontal axis and the minor street hourly volumes( one direction only) on the vertical axis. The minor street volume must fall above the curve for the corresponding major street volume for any four hours on an average day. A ten hour traffic turning movment count was taken at the Nani Kailua Drive/Kakalina Street intersection on September 9, 2003, from 7:00 A.M. to 5:00 P.M., to obtain hourly traffic volumes on the major and minor streets. These traffic counts require traffic surveyors to position themselves at the intersection and record through and turning movements by 15 minute intervals. The traffic count worksheets are included in the Appendix. The hourly volumes were compared against the Warrants 1 and 2 volumes to determine whether or not the current traffic volumes exceeded the warrant volumes for more than eight hours a day. If any or both of the warrants were met, then the study intersection would be warranted for traffic control signalization, and the four way stop control would be warranted as a stop gap measure. The results of this analysis are reported in the next section. 7.
