35 APPLYING VISTRO FOR THE PROJECT 35

36 GOALS OF TRAFFIC ANALYSIS - Evaluate multiple land use scenarios and network scenarios - Analysis to support the Master Plan - Communication of impacts to stakeholders - Determine mitigation for project I Slide 36

37 ANALYSIS TIMELINE - Small TIA Type Study - Expansion to Larger Study Area - Expanded # of Scenarios - Initial TIS Completed - Synchro + Spreadsheets - Master Plan Update w/synchro - Converted to VISTRO - Additional Scenario Testing Start of Traffic Study: Started as small study - TIA type study, completed in Synchro & Excel - Too complicated with too many land use scenarios - Spreadsheet tracking was not working well - VISTRO Analysis: Expansion to larger study/master Plan searched for tools to use and TRAFFIX/VISTRO was selected - CH2M s 1 st project in VISTRO Started in VISTRO 1.0/updated to VISTRO I Slide 37

38 ANALYSIS ASSUMPTIONS - Network Assumptions - Closure of Jefferson Avenue (Project Alternative) - Conversion of 3 rd -4 th and 5 th -6 th couplets to 2-Way street (Planned) - Land Use Assumptions - 5 Land Use scenarios evaluated in Master Plan - 1 Land Use scenario analyzed in VISTRO - Peak Hour/Forecast Years - AM/PM Peak hours analyzed (Existing), 2024 and 2035 Forecast years I Slide 38

39 STUDY AREA INTERSECTIONS - 23 Study Intersections - Generally bounded by - Fort Street/State Street (north) - 5 th Street (west) - Main Street (south) - Avenue B (east) I Slide 39

40 TRIP GENERATION AND TRIP DISTRIBUTION/ASSIGNMENT - Trip Generation based on previous ITE calculations - Input into VISTRO from Excel Spreadsheet - Did not calculate trips using rate inputs into VISTRO - Trip Distribution/Assignment - Based upon counts, regional forecasts, and local judgment - Patient surveys also used to determine future patterns - 40% - south, 30% -west, 20% - north, 10% - east I Slide 40

41 VISTRO NETWORK - 10 Trip Generation Zones - 9 Gates - 23 Intersections - 9 Signals - 13 Unsignalized - 1 Roundabout I Slide 41

42 VISTRO NETWORK OTHER NOTES - Traffic Analysis - HCM 2010 Methodology - Initially Integrated with a VISSIM network, but did not fully develop out that network due to change in project goals - Calculated trip generation in Excel, transferred to VISTRO - Modeling adjustment made at key locations - Jefferson Street Closure - Grid Network Assignment - 1-Way to 2-Way Conversion I Slide 42

43 VISTRO NETWORK SCENARIO TESTING - Standard Scenarios - Existing, No Build, Build , 2024, 2035 for AM and PM Peak hours - Additional Testing - Signals vs. Roundabouts - Closures vs. Non Closure (Jefferson, 1 st Avenue) - 2-way vs. 1-way traffic operations - Land Use Growth: High vs. Low intensity - Site Plan Adjustments I Slide 43

44 VISTRO NETWORK JEFFERSON CLOSURE Closure of Jefferson Avenue to Vehicle Traffic - Negative Trip Generation & Distribution for link via Zones 14/15 and 16/17 - Manual assignment based on counts/models runs I Slide 44

45 VISTRO NETWORK GRID NETWORK ADJUSTMENTS - For some areas, dummy nodes were created to accommodate paths - Especially prevalent in grids with many paths between O-D pairs - Lesson Identify dummy nodes ahead of time to keep network consistent Dummy Nodes on 2 nd Street to accommodate Paths I Slide 45

46 VISTRO NETWORK COUPLET TO 2-WAY CONVERSION - Manually adjusted volumes within Base network based on demand models - Decided against negative distributions like the Jefferson closure since it was not part of core study area - Affected 6 study intersections 3 rd /4 th Couplet to 2-Way Traffic I Slide 46
