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

4
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

5
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)

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

Interlocal Agreement AmongBellevue-Kirkland-Redmo
nd

• 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
