Design Hour FactorA 30th highest hour factor was developed for I-71 volumes within the Part B Study areausing hourly count data for the entire 2004 calendar year from a pair of directional ARTIMISATR stations located just north of Blair Avenue at SLM 4.20. These stations were chosensince they are in the same highway segments as a 48-hour field count conducted by OKI'straffic counting consultant during July 2005.The peak hour volumes were balanced north and south based on the adjusted peak hourvolumes from this OKI field count. From the 2004 data, the peak hour volume for eachweekday, excluding holidays, was identified and the average weekday peak hour volume forthe entire year was calculated for that location. The ARTIMIS count data was also used todetermine the 30th highest hour volume at this location on I-71. The 30th highest houradjustment factor was calculated for the ATR pair. This factor is simply the 120th highesthourly volume (by 15-minute increments) divided by the average weekday volume. Thisfactor was determined to be 1.112. This methodology was reviewed and approved by theODOT Office of Technical Services in December 2005.Uptown Transportation Study 35URS CorporationNovember 2006
