Slide 5:  I-35W Smart Lanes

[This slide contains a photograph of ILCS along a Minnesota roadway.]

Slide 6:  ILCS Sign Options

[This slide displays the messages and symbols used for ILCS. A blank black sign provides no traffic information. A green arrow signifies an open lane, that the PDSL is open, and/or that a lane is not effected by an incident. A flashing yellow arrow signifies that a lane is adjacent to an incident lane or incident shoulder; it's not in the Federal Manual on Uniform Traffic Control Devices (MUTCD). A red X signifies that a lane is closed due to an incident or for a closed PDSL. Prior to a Red X, the ILCS sign will display a yellow X, followed by a Merge with left or right chevron. The Merge with chevron is not in the Federal MUTCD and is currently being used as a request to experiment. Amber on black displays are advisory speed limits. A white diamond signifies that HOT lane restrictions are in place during peak periods.]

Slide 7:  Use of ILCS During Incidents; Right Lane Closed

[This slide contains a diagram of a section of five freeway lanes with five locations of ILCS and their states displayed during an incident where the right lane is closed. A red-highlighted section in the last four lanes represents congested traffic.]
