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
