<br />3 of 12 <br /> <br />Traffic Analysis Methodology <br />TransModeler, a simulation-based traffic analysis platform, was used to analyze traffic patterns and <br />travel time estimates from a system perspective. This platform keeps track of individual vehicle <br />movements and considers interactions between upstream and downstream intersections. Its <br />fiexible modeling capabilities and visual interface enhance both accuracy and interpretation. <br />Using traffic volumes and turning movement data reported in the TIA, WSB developed a systemwide <br />origin-destination (O-D) table. This table was then strategically disaggregated into: <br />• Local residential trips <br />• Proposed development (“Site”) trips <br />• Thru trips <br />O-D trip tables were iteratively adjusted to obtain balanced and realistic traffic patterns based on <br />travel time analysis. Scenario 2 of the 2045 design year was analyzed for this study. <br />Proposed Development Trip Routing <br />The Northwest Main Street development will provide multiple access points to the surrounding road <br />network as shown in Figure 1. Access A and Access C are expected to serve as the primary <br />outbound routes during the morning peak hour, as they offer direct and efficient access to major <br />roads. <br />The TIA assumed that a large share of site trips would travel through local residential streets. These <br />routes would result in longer travel distances, increased travel times and require passing through <br />multiple stop-controlled intersections—despite minimal congestion being expected on major <br />roads. <br />This study reevaluated routes that new development trips would use and it was determined that <br />these trips would use Access A and Access C, thereby minimizing impacts on the local residential <br />streets. This revised routing approach maintains a Level of Service (LOS) A at all major intersections <br />during the 2045 morning peak hour. <br />Tables A through D present a comparison of trip routing assumptions between the TIA and this <br />study. Figures 2 and 4 present intersection turning movement estimates for local residential, site, <br />and all trips under Design Year (2045) Scenario 2, respectively. <br /> <br />Page 8 of 228
