8. Trip Distribution a. Minimum Development Scenario Baseline Distribution The directional trip distribution for the site-generated traffic was developed based on a review of existing traffic patterns and users and the Twin Cities Regional Travel Demand Model. The Figure T11 anticipated directional trip distribution for site users is shown in . For the baseline scenario, roadway improvements include items described previously for the existing, No Build and Baseline transportation networks. The associated site generated turning movement volumes for the Minimum Development Scenario Figure T14 Baseline Distribution are shown in , and the total resulting turn movement volumes for the Figure T15 scenario are shown in . For these baseline (unmitigated) development scenarios, access to I-35W southbound from the project site is not provided from County Road H. Therefore access to I-35W requires trips to continue further west to the intersection of County Road H and TH 10, to gain access to southbound I-35W. b. Maximum Development Scenario Baseline Distribution Figure T16 The associated site generated turning movement volumes are shown in , and the total Figure T17 resulting turn movement volumes for the scenario are shown in . For this unmitigated development scenario, access to I-35W southbound from the project site is provided via a reconstructed loop from County Road H with the addition of a divided ramp that crosses under the TH 10 southbound entrance to I 35W southbound. Therefore trips destined to I-35W southbound no longer continue west to the intersection of County Road H at TH 10 to gain access to I-35W southbound. c. Minimum Development Scenario Mitigated Distribution The directional trip distribution for the Maximum Development Scenario Mitigated Distribution is Figure T12 shown in . Because the mitigation scenarios were analyzed with varying transportation system networks, the site-generated traffic distribution varies by scenario. Mitigation measures described in the roadway geometry section of this document includes the re-introduction of CR H southbound loop access to I-35W (removed as part of the baseline scenarios), which remains barrier separated from I-35W southbound exit ramp to TH 10 southbound, and enters I-35W after joining the TH 10 southbound access ramp to I-35W southbound. This change impacts site trip distribution and Figure T18 the result is shown in , and the total resulting turn movement volumes for the scenario are Figure T19. shown in d. Maximum Development Scenario Mitigated Distribution The directional trip distribution for the Maximum Development Scenario Mitigated Distribution is Figure T13 shown in . In addition to the Minimum Development Scenario mitigation measure, the Maximum Development Scenario mitigation measures also include the addition of a new northbound I-35W exit to CR H, with a single lane approach to the roundabout on CR H. This change impacts site Figure T20 trip distribution and the result is shown in , and the total resulting turn movement volumes Figure T21. for the scenario are shown in TCAAP Traffic Analysis Technical Memorandum 16 March 2014
