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 Workeherl <br />Psopal Mama <br />5*+01a v+wKw, <br />tarMen <br />0ri.i <br />ilv7.rorav ? 0 Access Prarm.'rr„ Sruov <br />rs2;O&O1 <br />J)-f 124 'hLrsrora <br />Nwamter 5. 201 <br />Fkor.olin <br />for In1M246110412 <br />1 <br />TYPE OF INTERSECTION <br />Shaer '...kww <br />CLV VC <br />Lb.liat.sz. <br />CLV 4f.'C <br />Y..., F...-de a ..rw.�. . r.-.I Cm-. <br />CLV V C CLV V C GLV V C <br />0, 0,0vr, Ranking <br />Rolm <br />1 <br />Cm...m lnna! <br />FLlltl <br />1545 6L7 $..47 5 <br />2 <br />OurmentiunaI Shorn] RT11'4 <br />GSA4 <br />11631 ".. 102 11 <br />3.1 <br />32 <br />3.3 <br />3.4 <br />0W4tAtti1 I1.W6 'i, <br />w <br />11.6 <br />I <br />ME <br />050 5. <br />471 Q 7 <br />- <br />562 az <br />Al <br />2896 1.41 <br />1E16 1.01 <br />PP. <br />1544 0.49 1.01 <br />1417 544 1.61 <br />1414 2,22 2.92 <br />1211 ,,,5Et 1.60 <br />1e <br />14 <br />3 <br />9 <br />2 <br />1 <br />1 <br />454 LZF <br />582 <br />41111 <br />1602 j <br />4.1 <br />4,2 <br />PMr,al 0, 4I. cAd Lail Turn <br />lil <br />116 <br />377 ILE <br />148 kis <br />-. <br />015 2jj <br />1447 LK 6.947 <br />.. - <br />- <br />466 ga <br />1478 222 <br />1473 Eisi 0.55 <br />5 <br />6iap'auv21.01Tun Ej.la <br />377 Lk{ <br />1439 LW <br />613 2.22 <br />1356 QA2 G. <br />61 <br />6.2 <br />7,1 <br />f,t <br />Ro-eln[latl CrosaInq li.
