CONCEPTS CONSIDERED <br />CONCEPTS CONSIDERED <br />A toolbox of potential improvement strategies was developed early in the concept development phase of study <br />as a means to guide MnDOT and Anoka County in considering a range of potential solutions. The toolbox provided <br />examples of lower-cost high -benefit improvements that have worked in other metropolitan regions. Multiple <br />improvement strategies were assembled for access management, reduced -conflict intersections and grade sep- <br />aration approaches. A copy of the Concept Improvement Toolbox is included in Appendix C. <br />Prior to developing specific concepts for each subarea, a high level screening process was used to limit concept <br />options to those that could actually improve capacity based on 2013 volumes. The Federal Highway Administra- <br />tion (FHWAJ, developed a tool called CAP -X that was used for this purpose. Based on turning movement volumes <br />and truck percentages, the tool ran a capacity analysis for multiple different at -grade, roundabout, and grade <br />separated intersection types. Different lane configurations were entered for each intersection type, and for this <br />purpose a compatible geometry with existing conditions was chosen. <br />For example, images of the Thurston Ave. evening rush hour analysis are included. The results show poor volume <br />to capacity ratios for all at -grade intersections and roundabouts, which led the concept development at this <br />location towards something grade -separated. <br />Capacity Analysis for Planning of Junctions <br />(Input Workehee9 <br />rp°ira' x....! <br />Highway PO Amass €'Taarxvlg Snmy <br />R4suIt$ <br />CrNreafl 9amryarla7ls Sum <br />1:9 >wp.4w- <br />142woo <br />., 1t00 <br />F.ccrptehla Canlllluru.'rs <br />iMD, 1. <br />'1504 <br />15 <br />1 <br />Loerle•..' <br />TNr6.1 Ma'am Aro WOAM1 <br />Mal <br />0.1.! <br />Nowomtar 5. 2413 <br />7 <br />1 7 <br />HIGHWAY 10 ACCESS PLANNING STUDY <br />Thurston Ave. CAP-XAM-1 <br />41 <br />R4suIt$ <br />lar Intosackla413 <br />V <br />TYPE INTERSECTION <br />r.i.ru.d,l <br />Shaer <br />GLV Y•C <br />Sane1ia.o} <br />CLV V.0 <br />•..111..1, a,..1r41.s.. 2.-.s r..-.:. ovo,811rr, <br />CLV VAC GLV V C GLV V C RolmRouting <br />1 <br />Cnnwbrylpnal <br />FLIL I <br />Mal <br />MOM <br />MOM <br />III <br />1545 0' 7 $..47 1 <br />2 <br />w ntiona4 Shared P1 LP <br />CSRL <br />Praia <br />I <br />Firl11PrAMPil1131 <br />],QQ 1.02 11 <br />3.1'S_1N' <br />a 2 <br />li_F <br />ilE <br />471 Q17PlirAlir <br />2496 1.41 <br />111616 1.01 <br />rdMill1417 <br />1584 0.49 1.01 141 <br />DM 1.61 14 <br />3.3 <br />3,4 <br />fkau1r.ani Itrwelwap <br />le <br />Iket <br />P <br />434 ga <br />In <br />562FAIN <br />1414 $,22 au 3 <br />1331 L X 5 <br />PIP-IiPil <br />l <br />14012+1 <br />6.1 <br />P1lr,il 0,4Istatl Turn <br />$ <br />877 <br />1164 g, t9IliE <br />1447 D 0.90 3 <br />4.2 <br />Lbi <br />Ea <br />PAPIPPATO <br />14341 Dig <br />- <br />693 F,31 <br />1473 Hsi 3,47 1. 4 <br />S <br />6iapl* *JLePoTwrn <br />Eza. <br />077 I& <br />1366 MI 4.40 1 <br />Si <br />6.2 <br />7,1 <br />7.2 <br />Ro-eiriclad CeossInq U.
