My understanding is that this development could <br />include a myriad of light manufacturing, warehousing, fulfillment services and research labs (among <br />others) and that simply having one "type" of use (i.e. warehouses) would have different traffic patterns <br />from business with 9-to-5 operational hours (and predictable peak times). <br /> The predicted new trips generated is 3,648 per average weekday with 320 AM peak trips and 326 PM <br />peak trips. These AM/PM "peaks" represent only 18% of all trips, which seems small for peaks. And, <br />similarly to what I stated above, if the entire development is warehouses (with more than AM and PM <br />peaks), this could cause issues with some of the lower-performing LOS intersections (and overall greater <br />rates of congestion in the area). <br /> A dedicated right-turn lane on southbound Old NC 86 is not recommended as there does not appear to <br />be enough ROW to construct the lane, but this is the connection to three (A, B and C) of the four <br />total driveways that will be constructed (the fourth, D, will be on Davis Rd.). These are also the first <br />three driveways that will be constructed, so it seems like a dedicated right turn off of Old NC 86 might <br />be important to functional operation of this area (especially since it's current use based on counts has <br />been zero). <br /> The three "exceptions" that do not meet LOS D or better for average intersections are all predicted on a <br />"typical" AM and PM peak time (and then down time in-between). Not sure that this will be the case if <br />the majority/entirety of the development is warehousing. <br /> All consultant recommendations seem sensible and realistic. <br /> The turn movements were calculated in October of 2016; I'm not sure how valid this data may still be (I <br />have no frame of reference for how old is "too old"). <br /> Page 31, Table 8: Old NC 86 at I-40 EB has an issue with maxing out the 200-feet of available storage <br />in AM; none of the recommendations call for an additional lane or improvement for this beyond a traffic <br />light. <br /> The overall conclusions (page 34) identify the problems with LOS E and LOS F for these particular <br />intersections, but offer no solutions. Turning north from WB I-40 onto Old NC 86 is simply going to be <br />slow, turning east from Old NC 86 onto EB I-40 is going to be slow, and turning out of the Service Road <br />(which houses three of the total four driveways for the development) onto Old NC 86 is going to be <br />slow. That's it. <br /> <br />Michael, this is my first analysis, so please let me know if anything else needs elaboration or if you have any <br />other feedback for me. Hoping this is enough to start. <br /> <br />214
