Transportation Network Analysis Scenarios <br />Due to increases in background traffic and the proposed TCAAP redevelopment, transportation <br />network changes are anticipated to occur in the future. Several long term improvements are being <br />considered in the project study area. Changes at the CR H and I-35W interchange will influence trip <br />Figure T3 <br />distribution for the proposed TCAAP project. These projects are shown in .A description <br />of the various transportation networks under each scenario is included below. <br />Internal Site Development Roadway System <br />The internal roadway system will consist of a north/south spine road, owned and operated by Ramsey <br />County in addition to a network of local streets. The spine road will be consistent with County State <br />Aid Standards (CSAH) for intersection spacing which is ¼ mile minimum spacing for full access <br />1 <br />intersections and/ minimum spacing for right-in/right-out accesses. The minor streets will primarily <br />8 <br />provide access to residences and private businesses accesses.As the site development is refined, <br />the roadway system will be modified to provide access, sustaining access spacing requirements <br />result in reasonable mobility. <br />Local and Regional Roadway System Connections <br />The transportation network analysis for the surrounding system has been analyzed for the following <br />conditions: <br />1) Existing <br />Figure T4 <br />The existing roadway geometry is shown on . This scenario considers the following: <br /> Existing traffic <br /> Existing roadway geometry including the recently completed construction of the TH 10/CSAH <br />96 interchange completed in 2013. <br />2) 2030 No Build <br />Figure T5 <br />The 2030 No Build roadway geometry is shown on . <br /> 2030 background traffic <br />2030 roadway geometry that include programmed improvements. The only difference <br />between existing and 2030 is the addition of Highway Safety Improvement Program (HSIP) <br />funded improvements at the intersection of TH10 at County Road H. The changes include <br />modifying the current shared westbound through/left turn lane into an exclusive westbound <br />through lane, and an exclusive westbound left turn lane and traffic signal phase <br />modifications. <br />3) 2030 Baseline for the Minimum Development Scenario <br />Figure T6 <br />The 2030 Baseline geometry is shown on . The following infrastructure improvements <br />are included: <br /> Improvements described above for the 2030 No Build Scenario <br /> CR 96 and I-35W area improvements: <br /> Construct traffic signals at the: <br />o <br />CR96/Old Highway 8 and <br /> I-35W Interchange ramp terminals intersections. <br /> Provide two eastbound and two westbound through lanes between Old Highway 8 <br />o <br />and Round Lake Boulevard <br /> Provide two eastbound and westbound left turn lanes to access I-35W <br />o <br /> Old Highway 8 at CR 96 Intersection: <br />o <br /> Replace shared northbound through / right turn lane with one exclusive <br />northbound through lane and one exclusive northbound right turn lane <br />TCAAP Traffic Analysis <br />Technical Memorandum 6 March 2014 <br />
