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

2 Presentation 1. EGN ( What It Would Take To Reduce Congestion 25%) –Study Parameters Demand /Supply Congestion Identify Projects Measure Effectiveness Rank Projects 2. 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
