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

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
