Steve jankowski - 2 - <br /> <br />November 3, 1999 <br /> <br />Traffic Signal Warrants Analysis <br /> <br />The existing hourly approach traffic volumes at the TH 47 and 142nd Avenue intersection were <br />checked to determine if existing traffic volumes meet the warrant requirements for traffic signal <br />control installation. Based on results of the traffic signal warrants analysis, the existing traffic <br />volumes at the TH 47 and 142nd Avenue intersection meet the warrant requirements for <br />Warrant 2 -- Interruption of Continuous Traffic. Please note, the minor-street volume threshold <br />to meet Warrant 2 is 70 vehicle per hour for eight hours. The actual minor-street volume ranges <br />from 83 to 70 vehicles during' these hours; therefore, barely exceeding the required threshold. <br />The existing traffic volumes did not meet any hour for Warrant 1 -- Minimum Volume <br />Requirement, nor any other warrant. <br /> <br />Conclusion <br /> <br />' Ti~-e "intersection ba~ely' nTl~et~S-'Warrant 2, and meets no other warrants.: However, drivers find <br />iht'ed:fi ~" so'ritl:ib'6~{iq'd' TH ~5 at 142h-a' ~-~4i'~'"i73-b~-"difficul't- dufin'~' tk~Tm, peak period. There <br />were 40 to 50 vehicles that were obse~ed cu~ing t~ough the parking lot located southeast of the <br />TH 47 and 147d Street intersection. These vehicles were avoiding the delays for ~ming le~ <br />onto TH 47 and were headed for CS~ 116. The question remains as to how much of the traffic <br />using 142"~ Street would dive~ to the CS~ 5/~mo intersection ~er those sisals are <br />installed. <br /> <br />Should you have any questions or comments concerning this study, please contact us. <br /> <br />DRE/DR/bba <br /> <br />Attachments <br /> <br />CC~ <br /> <br />A1 Pint, Mn/DOT <br />Mike Gerbensky, Mn/DOT <br />Wei Zhang, Mn/DOT <br /> <br />K:kPlan-Tr alX2960.Tklan kowski - l 1-3-99.doc <br /> <br /> <br />
