Copart USA Traffic Impact Study Elk River, MN 1/14/2020 warehouse facilities with a wide variation in the proportion of each type of use from one location to another." According to the Trip Generation Manual, a typical used car lot could range up to 5,000 square feet, while a new car lot could range up to 80,000 square feet. If there were a series of used car dealerships on this 47 acre site, the resulting trip generation would exceed 55,000 trips per day, or 7,600 trips per peak hour. 4. TRAFFIC IMPACTS In looking at the new Copart facility, the peak hour trip generation potential is small. The peak hour impacts these trips may have at the intersection of TH 10 and Jarvis Street may be offset by the reduction in trips generated by the metal pipe storage yard. Further, while all of the trip generation of the Copart site are shown utilizing the TH 10 intersection, it is possible some trips may exit and enter the site to and from the north. It is also noted that peak hour trips generated by this site may be limited to employee trips. The vast majority of off-peak trips generated by the site will be from delivery trucks that come into and out of the site throughout operating hours. There may also be a few in - person customers who travel to and from the site throughout the business day. 5. TRIP ASSIGNMENT Westwood utilized a review of existing traffic patterns to determine the proportional split of trips entering and exiting the development during each peak hour tested. Adjustments have been made to conform to more realistic expectations for trips being distributed directionally in this analysis. While some existing traffic counts may show zero trips during peak hours, it cannot be assumed that no trips will be generated by adjacent development. Therefore, a percentage of trips, however small, has been added to the distribution. These distributions were applied to the 2023 No -Build networks to model the Build conditions in each scenario. The peak hour trip assignment for this site are shown on Figures 4. 6. 2023 BUILD OPERATION AND PERFORMANCE Westwood has modeled the 2023 Build scenarios under the access conditions using the industry -standard Synchro/Sim Traffic software, Version 10. This software package provides the ability to perform level -of -service analysis, traffic simulation and optimization. 12 Westwood
