  1. Beginning –Constellation Pegasus EMME/2 Model Application End Gridlock Now Commissioned By Kemper Freeman, Jr. Lead By Dr. Bill Eager, TDA Inc.  Presented To 17th International EMME/2 Users’ Group Conference Calgary, Alberta, Canada October 2003 By Clyde Scott, Parametrix

  2. Presentation • EGN (What It Would Take To Reduce Congestion 25%) • Study Parameters • Demand /Supply • Congestion • Identify Projects • Measure Effectiveness • Rank Projects • EMME/2 Application • All-or-Nothing Assignments • Equilibrium Assignments • Additional Demand Options • Scalar Exports to Excel

  3. EGN • Scenario 2020 MTP – Demand Fixed • Delay - Unconstrained minus Constrained VHT • Project Definition • Freeflow Demand > Capacity = (Excess Demand) • Excess Demand/(Lane Capacity) = (Lane Needs) • Project Definition (MTP Plus Additional Lanes) • Travel Characteristics • System-Wide VMT, VHT, & Average Trip Length • Project-Using Subset of Trip Table • Assigned to EGN Network (Travel Characteristics) • Compared to 1998 Travel Characteristics

  4. Model Flow E n i f

  5. Length Constrained Lane Needs

  6. Project List

  7. EMME/2 Model Application • Measure The Effectiveness of Individual Projects • Within A Framework of A Comprehensive Package of Projects • Consistent Comparison To Scenario Alternatives • Existing Conditions • No-Build • Efficient EMME/2 Macro • Linkage to Excel Spreadsheets E n i f

  8. Typical Measures of VMT & VHT • System Wide • Network Skims • By Link Type or VDF(EMME/2 defaults) • By Link Attribute • For All Auto Modes • Matrix Calculations • Sub-Area Summaries • Select Paths – Additional Demand Options • Network Skims • Select Link • Select Segments • Matrix Calculations • Sub-Set of Trip Table (FromSelect Link)
