Roadway Network A total of six forecast scenarios were prepared for the CSAH 5 Corridor Traffic Study. This includes existing year 2018 conditions along with five scenarios representing future year 2040 conditions. The following scenarios were included in the CSAH 5 Corridor Traffic Study: • Existing (2018) -year 2018 SE data and the year 2018 roadway network • 2040 No Improvement—year 2040 SE data with year 2018 roadway network • 2040 Baseline — year 2040 SE data with all programmed improvements; CSAH 5 as 2-lane undivided with 8-foot shoulders • 2040 Alternative 1 — year 2040 SE data; CSAH 5 as 2-lane rural section with painted center median, 8-foot shoulders, and left and/or right turn lanes at major intersections • 2040 Alternative 2 — year 2040 SE data; CSAH 5 as 2-lane rural section with a raised center median, 8-foot shoulders, and left and/or right turn lanes at major intersections • 2040 Alternative 3 — year 2040 SE data; CSAH 5 as 4-lane rural section with a raised center median, 8-foot shoulders, and left and/or right turn lanes at major intersections Additionally, the following programmed roadway capacity improvements within the study area were incorporated into the ABM roadway network for the year 2040 Baseline and Alternative Scenarios: • Highway 47 and County Road 116/Bunker Lake Boulevard intersection improvements • Highway 47/169 resurfacing • Highway 10 Ramsey Boulevard /Sunfish Lake Boulevard interchange construction • Highway 10 Rum River bridge replacement and corridor improvements • Fairoak/Thurston/U Main Street interchange construction • Highway 47 BNSF Railroad grade separation • Highway 10 strategic congestion mitigation • Highway 10 at Round Lake Boulevard intersection improvements • Highway 169 Redefine/freeway construction Travel Demand Model Validation For this study, the ABM validation was reviewed in the study area shown in Figure 1. Validation is defined as the degree to which the travel demand model replicates known ground counts. The traffic counts used for the validation were obtained from the MnDOT Traffic Forecasting and Analysis published data. Based on the ABM validation review completed for this study, the model validates to accepted industry standards. Traffic Forecast Results Daily traffic forecasts were prepared for the No Improvement scenario to capture the growth in the study area due to development growth.The No Improvement scenario forecasts are shown in Figure 2. 11
