Emergency Exit Signs and Marking Systems for Highway Tunnels

TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 216: Emergency Exit Signs and Marking Systems for Highway Tunnels focuses on determining effective messages for encouraging drivers to leave their vehicles and evacuate a tunnel on foot; determining sign and marking formats that most effectively lead people to emergency tunnel exits; and determining the most visible sign and marking materials and technologies for use in highway tunnel environments.

A brochure, Proposed Guidelines for Emergency Exit Signs and Marking Systems for Highway Tunnels, complements the report.
