considered by Ramsey County and MnDOT adjacent to the AUAR study area. Changes at the CR H and I- 35W interchange will influence trip distribution for the proposed AUAR study area. These improvements are shown inFigure 18-1. A description of the various transportation networks assumed under each scenario is included below. Internal Site Development Roadway System The internal roadway system will consist of a north/south spine road, owned and operated by Ramsey County in addition to a network of local streets. The spine road will be consistent with County State Aid Standards (CSAH) for intersection spacing which is ¼ mile minimum spacing for full access intersections and/ minimum spacing for right-in/right-out accesses. The intent of the County would be to have the 1 8 roadway classified as a Class A Minor Arterial Highway Expander. The minor streets will primarily provide access to residences and private businesses accesses. As the site development is refined, the roadway system will be modified to provide access, while also satisfying access spacing requirements to maintain reasonable mobility. Local and Regional Roadway System Connections The transportation network analysis for the surrounding system has been analyzed for the following conditions: Existing The existing roadway geometry is shown onFigure T4 (AppendixCD). This scenario considers existing traffic and existing roadway geometry including the recently completed construction of the TH 10/CR 96 interchange completed in 2013. 2030 No Build The 2030 No Build roadway geometry is shown onFigure T5 (AppendixCD). This scenario considers 2030 background traffic and 2030 roadway geometry that include programmed improvements. The only difference between existing and 2030 is the addition of Highway Safety Improvement Program (HSIP) funded improvements at the intersection of TH10 at County Road H. 2030 Baseline for the Minimum Development Scenario The 2030 Baseline geometry is shown onFigure T6 (AppendixDC). This scenario considers infrastructure improvements at the CR 96 and I-35W interchange, Old Highway 8 at CR 96 intersection, CR H and I35W interchange, and CR 10 and CR H intersection 2030 Baseline for Maximum Development Scenario The infrastructure improvements for this scenario are the same as in Minimum development scenario. Traffic Study Area Figure T4(AppendixDC)shows the 14 intersections that were analyzed. Local Roadway System Traffic Operations Analysis Methodology The traffic operations analysis for the local roadway system was completed in Synchro/SimTraffic, a software program that applies the methodologies of the Highway Capacity Manual. This tool was used to evaluate intersection volume/capacity ratio, delay, and level of service, and queuing. Capacity analysis results identify a Level of Service (LOS) which indicates how well an intersection operates. Intersections are given a ranking from LOS A through LOS F. LOS A indicates the best traffic operation and LOS F indicates June 2014– Final AUAR25
