Transcripción del resumen del autor. A two-year international road tunnel fire detection research project (Phase II) was completed recently. As part of this project, a series of fire tests were conducted in a laboratory tunnel facility under minimum and longitudinal airflow conditions. In addition, fire tests were also conducted in the Carré-Viger tunnel in Montreal. This paper presents the results of the full-scale experiments conducted in the laboratory tunnel under minimum airflow conditions. The performance of nine fire detection systems representing five types of fire detection technologies was investigated using representative tunnel fire scenarios. Test results showed that the response of fire detection systems to a tunnel fire was dependent on the size, location and growth rate of the fire, the type of fuel as well as the method of detection.
