<br /> <br /> <br />COUNTY ROAD E & OLD SNELLING AVENUE ICE PAGE 8 <br />WSB PROJECT NO. 011498-000 <br />CITY OF ARDEN HILLS <br />Traffic Control Analysis <br /> <br />The following subsections detail the analysis used for determining the appropriate traffic <br />control for this intersection. Twelve hours of turning movements (6:00 AM-6:00 PM) were <br />counted on February 7, 2018 and used to perform a traffic signal warrant analysis and <br />all-way stop warrant analysis. <br /> <br />Traffic Signal Warrant Analysis <br /> <br />Part 4 of the Minnesota Manual on Uniform Traffic Control Devices (MnMUTCD) contains <br />information pertaining to highway traffic signals, including a series of traffic-signal <br />warrants that define the minimum conditions under which installing a traffic signal could <br />be justified. These traffic signal warrants have been developed as national guidelines to <br />promote continuity of traffic control devices and to ensure that traffic signals are installed <br />at intersections that benefit from their operations. The following are the nine MnMUTCD <br />traffic signal warrants: <br /> <br />Warrant 1-Eight-Hour Vehicle Volume <br />Warrant 2-Four-Hour Vehicle Volume <br />Warrant 3-Peak Hour Vehicle Volume <br />Warrant 4-Pedestrian Volume <br />Warrant 5-School Crossing <br />Warrant 6-Coordinated Signal System <br />Warrant 7-Crash Experience <br />Warrant 8-Roadway Network <br />Warrant 9-Intersection Near a Grade Crossing <br /> <br />Table 4C-1 70% volumes were also used for warrant analysis. The MnMUTCD allows <br />for use of these values when the conditions are as follows: <br /> <br />“May be used when the major-street speed exceeds 40 mph or in an isolated community <br />with a population of less than 10,000.” – MnMUTCD Table 4C-1, Warrant 1, Eight-Hour <br />Vehicular Volume. <br /> <br />According to the MnMUTCD, inclusion of right-turn volumes for warrant analysis is <br />dependent on engineering judgment, site factors and turning movement volumes. By <br />applying engineering judgment, right-turn movements on only the westbound approach <br />of the intersection were removed from the analysis due to the presence of a right-turn <br />lane. <br /> <br />The following is the result of the traffic signal warrant analysis. See Appendix C for <br />additional information. <br /> <br />ƒ Warrant 1 – Eight-Hour Vehicle Volume: NOT MET <br />ƒ Warrant 2 – Four-Hour Vehicle Volume: NOT MET
