AbstractToday?s increase in road traffic, changes in vehicle mix, and new rolling stock have resulted in an increase in the incidence of fatal fires in tunnels. In Europe, recent catastrophic tunnel fires have resulted in loss of life and severe property damage. Reliable and early fire detection in tunnels insures an early warning of a fire incident, allowing for timely activation of emergency systems. As such, detection can make the difference between a manageable fire and one that gets out-of-control [1, 2]. The Fire Protection Research Foundation recently completed an international research project, with the support of private and public-sector organizations to evaluate the performance of various types of detection [3]. The project studied the detection performance of nine fire detection systems representing five types of currently available fire detection technologies (Table 1), including their response times to a fire and ability to locate and monitor a fire in a tunnel, with both laboratory and field fire tests combined with computer modeling studies. In addition, the project also studied the reliability of the detection systems in harsh tunnel environments, such as their nuisance alarm immunity and requirements for maintenance.
