Rice Street /CR B Park- and -Ride Additional Traffic Analysis <br />May 10, 2011 <br />Page 2 <br />access. The intersection was assumed to have minor roadway stop control, and the park- and -ride and Cub Foods <br />approaches were assumed to have single shared left and right turn lanes. The Rice Street /TH 36 interchange and <br />Rice Street /CR B intersections were evaluated as part of the October 2010 analysis, and those results will not be <br />affected by the model changes made for this analysis. Therefore, only the CR B /Park -and -Ride Access was <br />evaluated for this analysis. <br />SimTraffic capacity analysis is a measure of traffic flow. 11 uses traffic volumes and operating conditions to <br />determine a Level of Service (LOS). The levels of service rage from "A" to "F ", with "A" being free flow, minimal <br />delay conditions, and "F" being forced /stopped flow conditions with significant delay. Typically in the metropolitan <br />area, intersection levels of service "D" and "E ", with no individual movement at LOS "F ", are acceptable during the <br />AM and PM peak hours. The results of the SimTraffic analysis are shown on Table 1. <br />The October 2010 analysis showed that the proposed park - and -ride intersection operates at LOS A during the AM <br />and PM peak hours, with all movements operating at LOS A in the AM peak hour and LOS B or better in the PM <br />peak hour. <br />As Table 1 shows, the proposed park - and - ride /Cub Foods access intersection operates at LOS A during the AM and <br />PM peak hours with the Cub Foods full access traffic included at this intersection. All individual movements <br />operate at LOS B or better during the AM peak hour, and all individual movements operate at LOS D or better <br />during the PM peak hour. <br />As with the October 2010 analysis, the delays and queues reported for the proposed park -and -ride approach are <br />based off hourly volumes with standard arrival rates. In reality, there will be periods of longer delays and queuing <br />during the PM peak hour when the busses drop off riders in the lot and those riders leave approximately around the <br />same time. However, stop control should be sufficient for the park - and -ride access. <br />The October 2010 analysis showed a maximum queue length for eastbound CR 13 left turn lane at the Park -and -Ride <br />Access as 127 feet during the AM peak hour. The additional analysis performed with the Cub Foods full access <br />shows a maximum queue length of 100 feet during the AM peak hour. This decrease in eastbound maximum left <br />turn queue length appears to be due to the decrease in westbound through vehicles which were redistributed to the <br />northbound Cub Foods access left - turning movement, The eastbound CR 13 left turn lane at the Park -and -Ride <br />Access should be at least 100 feet to accommodate left - turning vehicle queues. <br />October 2010 analysis showed a westbound left-turn maximum queue length of 159 feet at the Rice St /CR 13 <br />intersection in the PM peak hour. Therefore, the westbound CR B left turn lane should be at least 160 feet at the <br />Rice Street intersection to accommodate left - turning vehicle queues. The analysis also shows a westbound CR 13 <br />maximum through queue length of 400 feet in the AM peak hour and 293 feet in the PM peak hour at the Rice Street <br />intersection, and it is recommended that the westbound CR 13 left turn lane length remain at 330 feet so that left- <br />turning vehicles don't get caught in the through queue during the peak hours. <br />MPM <br />Attachment — Rice Street /CR 13 Park & Ride Additional Traffic Study MOE Table <br />c: Greg Finstad - SEH <br />c: \doc uncnIs and seiiinrs \i n iocivdy \desktop \park &ridc\addiliona1 p&r annlysisbice.crb par}.mnd- ride.docx <br />
