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 (FHWA), 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 Worksheei <br />rto)al urs..:l <br />Illghway 00 Amass Flamm Snyay <br />742 rgp <br />241. <br />TNrbdMa'am Avefedr3AM1 <br />Nwaamber 9. 22013 <br />Accrp[ehla Cvnliqurul,vrs <br />Firr.ul I., <br />'or InS0114C <br />i041$ <br />V <br />TYPE INTERSECTION <br />2ur:.rwd1 <br />Shaer <br />GLV V C <br />Xma tlasW <br />CLV V.'C <br />]u. f,r..ri d,..rw..1 2.-.s C.-..-. ovo,aiir r, <br />rIF11+O19 <br />CUE VAC CLV V C GLV V C Ratio <br />1 <br />CCIlIl <br />FLlli. <br />1531 J 1i <br />2 <br />SUM <br />P.nrfwiitloras1 Sher i RT LN <br />.CSAL <br />" <br />1631 la <br />1..4T <br />1 CC 11 <br />1.01 12 <br />1.61 12 <br />0.62 <br />Leo - 4 <br />3.1 <br />22 <br />6.3 <br />1.4 <br />1342 4M1 RooOk+1p <br />' -W <br />11F <br />;tE <br />&2t <br />959 <br />471 O. <br />662 Zaf <br />AllI616 <br />2444 1.. 21 <br />542 <br />1.01 <br />Will <br />1924 3 <br />1417 REIS <br />1464 Laz <br />Iasi <br />424 LZF <br />i9 2 fyg <br />4.1 <br />4.2 <br />P.irr,el 0iyplscad Lai Turn <br />lil <br />E__ <br />27,7 IV <br />196 lug <br />BM 2jj <br />1447 6�p <br />1473 212 <br />6.99 2 <br />isa gap <br />14so 344 <br />233 1 <br />S <br />6iep4wp.P1.e41Twru <br />Elm <br />177 g',g4 <br />1434 mg <br />613 F.$2 <br />11366 QA2 G. 1 <br />Si <br />2.2 <br />7,1$ <br />T,2 <br />Rasincled Crossing u= ruin <br />L <br />E <br />i071) gli <br />oss mg <br />1769 LE <br />4125 g2 <br />3996 Liii <br />I 2.3E 15 <br />ill IN <br />1292 LEF <br />1525 <br />I 037 5 <br />Median UTurn <br />W <br />3$4P <br />424 <br />1049 <br />1655 tilt <br />1761 la <br />1697 US <br />1=10 1$ <br />1.96 17 <br />/ <br />.. <br />Ai <br />&2 <br />Parlly iA[.di.1n LI-rum <br />N_S <br />E=w <br />26441%¢ <br />/ / <br />269 gm <br />- <br />1238 664 <br />1601 1:0 <br />1601 1= <br />102 7 <br />1730 7 <br />1029 LEF <br />Thurston Ave. CAP-XAM-1 <br />HIGHWAY 10 ACCESS PLANNING STUDY <br />41 <br />
