Josh Nyquist, Executive Director of Building OperationsApril28, 2022 PACT Charter School | Traffic Impact Study tğŭĻЌ Roadway Characteristics A field assessment was completed to identify various roadway characteristics within the study area transportation system, such as functional classification, general configuration, and posted speed limit. A summary of these roadway characteristics is shown in Table 1. Note that these are general characteristics and that there are some deviations within portions of roadway segments.

The segment of 161st Avenue between Armstrong Boulevard and Variolite Street has been identified to be improved/reconstructed as part of the City of Ramsey Capital Improvements Plan for year 2024. Design of this future 161st Avenue improvement/reconstruction is currently under consideration. It has been suggested that it may be possible to reschedule this 161st Avenue improvement and/or reconstruction to coincide with theproposed PACT Charter School project. Existing geometrics, traffic control, and traffic volumes in the study area are shown in Figure 2. Existing Intersection Traffic Operations/Capacity Analysis An existing intersection traffic operations/capacity analysis was completed to establish baseline conditions to which future traffic operations can be compared. The capacity analysis was completed for the a.m.and p.m.peak hours at the study intersectionsusing the Synchro/SimTrafficcomputer traffic simulation model. Capacity analysis results identify a Level of Service (LOS) which indicates the quality of traffic flow through an intersection. Intersections are given a ranking from LOS A through LOS F. The LOS results are based on average delay pervehicle, which correspond to the delay threshold values shown in Table 2. LOS A indicates the best traffic operation, with vehicles experiencing minimal delays. LOS F indicates an intersection where demand exceeds capacity, or a breakdown of traffic flow. Overall intersection LOS A through D aregenerally considered acceptable by driversin the Twin Cities Metropolitan Area. For side-street stop-controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an unsignalized intersection with side- street stop control can be described in two ways. First, consideration is given to the overall intersection level of service. This considersthe total number of vehicles entering the intersection and the capability of the intersection to support these volumes.
