AbstractThis paper presents the results of the full-scale experiments conducted in a laboratory tunnel facility under longitudinal airflow conditions and in the Carré-Viger Tunnel. The performance of nine fire detection systems representing five types of the fire detection technologies for road tunnel applications was investigated using representative tunnel fire scenarios. The changes in fire characteristics caused by longitudinal airflow, such as fuel burning time, fire growth rate, temperatures and smoke spread in the tunnel, were measured and analyzed. The experimental results showed that the detection time of the fire detection systems under longitudinal airflow conditions could be increased or decreased, depending on the fuel type, fire size and location, airflow velocity and detection method.
