The project's overall objective is to evaluate whether the illuminance provided in EN 16276: 2013 on emergency lighting in road tunnels is sufficient to fulfill its function in an emergency situation. The objectives of the project are to: 1. Based on the current state of research on human behavior in fires describe the function / features emergency lighting in road tunnels must meet during an evacuation in case of fire. 2. In a small laboratory test in a smoke-filled environment evaluate the design of various emergency lighting solutions, including with respect to illuminance.
