  3. 95 Express CORSIM Scope • Purpose • To model operational characteristics of the I-95 Express project . • Evaluate HOT ingress/egress locations based on weaving and access/proximity to interchanges. • Assessment based on freeway system operations • Project Scope • Stage 1: South of I-395 to North of GGI plus IOAR • Stage 2: North of GGI to North of I-595 • Stage 3: Corridor Assessment of HOT ingress/egress

  4. Existing Demand – Build Scenario 1,100 vph/ln 22% * 2,200 HOT Lanes 1,660 vph/ln 1,950 vph/ln 78% 7,800 10,000 vph GP Lanes * SERPM 2010 Build

  5. Speed – Flow – Density

  6. Weaving –Type A Weave All weaving vehicles must make one lane change to complete their maneuver successfully

  7. Weaving – Type B Weave One weaving movement can be made without making any lane changes while the other weaving movement requires at most one lane change

  8. Weaving – Type C Weave One weaving movement may be made without making a lane change while the other weaving movement requires two or more lane changes
