  1. Bellevue-Kirkland-RedmondTravel Demand Modeling Experience Jin Ren, P.E. City of Bellevue, Washington, USA October 19, 2004 18th International EMME/2 User’s Conference Mexico City, Mexico

  2. Introduction EMME/2 BKR Model Since 1991 • MP0 – Base Year Model Platform • MP6 – 6-Year Short-Range MP • MP12 – Mid-Range 12 Year MP • MP20 – Long-Range 20 Year MP • MP30 – Long-Range 30 Year MP

  3. BKR Model Enhancements • Migrating multiple off-model functions to a complete 4-step EMME/2 macro process • Tying trip generation to household cross-classification • Introducing multi-class (SOV and HOV) auto assignments • EMME/2 Network match-up with GIS tiger line file • Calibrating to the 1999 regional household travel survey • Updating with new 2000 census data • Building a transit modeling capability with capacity constrained assignment • Park-&-Ride lot capacity constrained mode splits

  4. BKR Model Application • Annual base year model calibration and validation (MP0) • Street closure/construction traffic diversion analysis (MP0) • Annual Transportation Concurrency Update (MP6) • Development review modeling (MP6) • 2015 Transportation Facility Plan Update (MP12) • 2004 update of traffic impact fee schedule (MP12 and MP6) • 2015 sub-area SOV/HOV traversal matrix (MP12) • 2020 Bellevue Downtown Implementation Plan (MP20) • Overlake Hospital Medical Center expansion (MP30)

  5. Base Year Model Trip Generation Table 1: Final Validation of Trip Generation Models for the BKR Study Area

  6. Base Year Model Trip Distribution Table 2: Final BKR Area Average Trip Duration by Purpose (minutes)

  7. Base Year Model Mode Choice Table 3: 2003 BKR MP0 R5 Mode Choice Model Results vs. 1999 Regional Survey

  12. Annual Transportation Concurrency Update (MP6)

  13. Development Review Modeling (MP6) Figure 8. City Center II Development PM PK Hour Select Project Trip Assignment

  14. 2015 Transportation Facility Plan (MP12) - Impact Fee Assessment • Select link TFP group assignments by 14 Sub-areas, based on MP12 (a downtown example is shown in Figure 9) • Select link TFP group assignments by 14 Sub-areas, based on MP6 (2003 Existing + Permitted LU) • Select link group trip tables by sub-area for MP12 and MP6 • Sub-area traffic growth rates related to TFP select link groups • TFP Growth Cost = (Sub-area traffic growth rates) X (TFP total costs by sub-area) • Average Cost Per Trip = TFP Growth Costs / Sub-area Trip Growth • Cost Per Trip by commercial, non-commercial and city-wide areas

  15. Select TFP Link Group in Downtown Bellevue Figure 9: 2015 Select TFP Link Group Identified in Downtown Bellevue

  20. Interlocal Agreement AmongBellevue-Kirkland-Redmond • BKR Model Platforms Are Shared Among BKR Partners • BKR Model Is Annually Maintained and Upgraded through Jurisdictional Partnership • Variety of EMME/2 Applications in the Cities of BKR • Time Savings, Cost Sharing, Data and Technical Support • Enhance Opportunities to Influence Transportation Decision Making at the Local, Sub-Regional and Regional Level Planning • These Benefits Are Demonstrated by the Above Discussed Examples
