HomeMy WebLinkAboutPVH MEDICAL OFFICE BUILDING & PARKING STRUCTURE - PDP - 14-07 - REPORTS - TRAFFIC STUDY (3)l queue length of 32 feet in the morning peak hour and 190 feet in the afternoon peak hour. From this analysis, it can be concluded that the driveways to the commercial property to the north would be blocked similar to that which occurs with the current traffic. The TIS analyzed two levels of expansion of PVH: Phase 1 - increase of the surgical area, renovation of the emergency department, and building the parking garage; and Phase 2 - a medical office building, central utility plant relocation, and a new patient bed tower. The following queue analysis depicts implementation of both Phase 1 and Phase 2 by the mid range future (2013). Using the mid range total peak hour traffic, the 95"' percentile southbound queue is calculated at 326 feet and 583 feet in the respective peak hours. Applying the adjustments, discussed earlier, results in a queue length of 40 feet in the morning peak hour and 190 feet in the afternoon peak hour. It is concluded that the driveways to the commercial property to the north would be blocked similar to that which occurs with the current traffic. The southbound right -turn lane will provide the ability for some of the right -turning vehicles to get out of the right -most southbound through lane. However, the southbound queue is primarily caused by general traffic on Lemay Avenue, not related to Poudre Valley Hospital. DELICH ASSOCIATES Traffic & T,ransportation Engineeringl' 2272 Glen Haven Drive Loveland Colorado 80538 Phone:(970) 669=2061 Fax: (970) 669-5034� r MEMORANDUM TO: Angie Milewski, BHA Design Marcia Lester, Davis Partnership City of Fort Collins FROM: Matt Delich DATE: August 8, 2007 SUBJECT: Expansion of the PVH Lemay Campus Transportation Impact Study - Queue analysis at the Lemay/Doctors intersection (File: 0692ME02) The following documents the analyses of the north leg of the Lemay/Doctors intersection. The owner of the commercial property to the north of the existing parking lot (future parking garage) expressed concern that the south driveway.is/would be blocked by traffic on Lemay Avenue. This driveway is approximately 120 feet north of the crosswalk for Lemay Avenue on the north side of Doctors Lane. There is a second driveway that is approximately 300 feet north of the crosswalk. The analyses contained herein address the peak hour conditions, since these are the time periods addressed in the traffic impact study (TIS). The analysis procedure determines the 95th percentile queue length. It is my understanding that the owner of the commercial property indicated that the southbound queue (upstream from the Lemay/Doctors signalized intersection) blocks the south driveway to his parcel. The operations analysis of the Lemay/Doctors intersection (current traffic - 11/15/06) shows that the 95th percentile southbound queue is calculated at 268 feet in the morning peak hour and 561 feet in the afternoon peak hour. Right turns into the PVH parking lot are made from the right -most through lane on Lemay Avenue. Observations were conducted on August 7 and 8, 2007, during the peak hours. In the morning peak hour, the average length of queue was 32 feet. In the afternoon peak hour, the average length of queue was 180 feet. Comparing the calculated queue length and the observed queue indicates that the analysis procedure over- estimates the actual queue length on the order of 8.4 times in the morning peak hour and 3.1 times in the afternoon peak hour. It is concluded that the calculated queue lengths should be adjusted accordingly to better reflect the field observations. It is further concluded that the south driveway is not blocked during the morning peak hour, but it is routinely blocked during the afternoon peak hour. The background traffic in the future analysis years depict the traffic forecast with no PVH expansion, but with the expected normal traffic growth in the area. Using the mid range (2013) background traffic forecast, the 95th percentile southbound queue is calculated at 270 feet in the morning peak hour and 588 feet in the afternoon peak hour. Applying the adjustments discussed in the previous paragraph results in a
