The16,500numberisalsogiven(as"dailytrafficvolume")inthe"ExecutiveSummary" <br />onPageiii.In a chartintheAppendix,theAverageDailytrafficvolume for 2012isgiven <br />as16,360. <br />Ithoughtthattheuseof a singlecounton a singledayinthemiddleofsummerwas <br />slipshod.And I wassurethattheyhadotherdatacollectedoverlongerperiodsandmore <br />places. It turnedoutthatitappearstohavebeen worsethanslipshod.InJanuaryofthis <br />year(2016),whilelookingforsomethingunrelated, I cameupon a mappublishedin <br />October2013bytheCityofEugene,PublicWorks - TransportationDivision.Thelabel <br />on that map said: “Counts Shown Represent Typical Weekday, 24 Hour Volume Counts”. It <br />addedthatthecountsweretaken from2006 - 2013.Sothatwasdataavailablein2013, <br />andsomeofitwouldhavebeenavailablebeforetheirplanningstarted.Thefigureof <br />16,500accords reasonablywellwiththe16,000givenonthemapforthesectionof <br />Willamettebetween27thand29th.Butthatwasnotthebusiestportionofthe24thto <br />32ndstretchofWillamette.Thebusiestsegmentwas from 24thto27th,wherethecount <br />onthemap isgiven as19,800.That’s20%higherthanthe16,500 figure,andisabout <br />24%higherthanthecomparableaverageof16,000givenonthemap.
