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
Page 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

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

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
