<br />level of service, based on control delay. Control delay is the delay experienced by vehicles <br />slowing down for a stop sign and the wait time at stop sign. Level of Service D is commonly <br />taken as an acceptable design year LOS. <br /> <br />Analvsis <br /> <br />The intersections were analyzed by the criteria listed above. Table 3 details the operational <br />results for the exiting conditions and for conditions after the connection is made. After the <br />connection is made no improvements to the intersections geometry were considered. <br /> <br />Table 3: Operational An~lysis <br />Intersection and Traffic Scenario Peak Hour Intersection Maximum Delay-LOS** <br />Control V olume* <br /> AM 699 12.6-B <br /> Existing .......... <br />TH 47 & 157lh Lane PM 925 11.7-B <br />Unsigna/ized With AM 708 12.7-B <br /> Connection PM 932 11.8-B <br /> AM 53 8.6-A <br />157lh Lane & Neon Street Existing PM 68 8.7-A <br />Un,signalized With AM 67 9.0-A <br /> Connection . ...... <br /> PM 83 9.2-A <br />*T otal number of vehicles utilizing the intersection during the peak hour <br />**Maximum delay and LOS on any approach and/or movement <br /> <br />The intersections analyzed can be expected to operate tlle same after the connection is made. The <br />traffic that is added from the connection is negligible and does not affect the level of service for <br />any of the intersection movements. <br /> <br />The existing traffic on I 57th Lane, just west of TH 47, was measured at 980 vehicles per day. <br />With the roadway extension, it is projected that there will be a maximum increase of 90 vehicles <br />per day (9% increase) for a total of 1,070 vehicles per day on I 57th Lane. <br /> <br />The existing traffic using Potassium Street to the South is estimated at 60 vehicles per day based _ <br />on recent counts. As the residential developments are completed, daily traffic is estimated at 520 <br />vehicles per day. With the roadway extension, it is projected that there will be a maximum <br />decrease of 50 vehicles per day for a total of 470 vehicles per day on Potassium Street. <br /> <br />Summary and Conclusions <br /> <br />The extension of Neon Street between Rum River Estates and 157th Lane, west ofTH 47 is an <br />important roadway connection for local traffic circulation to and from Nowthen Boulevard <br />(CSAR 5) and TH47. <br /> <br />1. This connection will increase the volume of traffic using I 57th Lane near TH 47 by <br />approximately 90 vehicles per day (9%), but operations will not decrease noticeably. <br /> <br />H:\RAMS\T4222096\Report\ExtensionTechMemo030707.doc <br />
