Trip Generation Though the development scenarios are unchanged from the 2014 AUAR, trip generation was updated to reflect updates in the source data (the Institute of Traffic Engineers (ITE) Trip Generation Manual). Trip generation for this AUAR Update was based on the 1 1 ih Edition of the Trip Generation Manual (published September 2021), while the 2014 AUAR traffic analysis utilized the newest version available at the time (the 9th Edition). Changes in the data resulted in an overall slight decrease in the number of trips anticipated to the site. A comparison of the updated trip generation numbers to the trip generation numbers used in the 2014 AUAR is shown below in Table 4.

Due to the large amount of roadway improvements that have been constructed since the 2014 AUAR traffic analysis, the study area has been reduced to include only the most heavily impacted intersections. The analysis was performed for weekday AM and PM peak hour conditions at the following intersections: • Mounds View Boulevard & County Road H (signalized) • CSAH 96 & US Highway 10 Southbound (SB) Ramp (signalized) • CSAH 96 & Northern Heights/TCAAP South Access (side -street stop) • County Road H & 1-35W SB Ramp (roundabout) • County Road H & 1-35W Northbound (NB) Ramp (roundabout) Capacity analysis was carried out using Synchro 1 1 (SimTraffic) at signalized and stop - controlled intersections, while analysis of roundabouts was carried out using roundabout analysis software Rodel. A summary of the LOS results of the network is shown below in Table 5. The overall intersection LOS is reported at signalized and roundabout intersections, while the worst side -street LOS is reported for side -street stop -controlled intersections. Roundabout results shown below are 50% confidence level results from Rodel. Note that the baseline build geometry at CSAH 96 & Northern Heights/TCAAP South Access included an installed traffic signal, two southbound left turn lanes, a southbound right turn lane, a southbound through lane, two eastbound left turn lanes, and a westbound right turn lane.
