Later, it was shown in full-scale fire tests within the SOLIT and SOLIT2 research projects that high-pressure water mist technology is very effective against heavy goods vehicle fires in tunnels . HGV fires are normally used as the design criterion since the aftermath of catastrophic fires has shown how severe they can :// A Synthesis of Highway Practice NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM NCHRP SYNTHESIS Design Fires in Road Tunnels
Some catastrophic fires occurred in the last 15 years in both road and railway tunnels used by millions of people are turning the attention of the engineering community towards the assessment of /_Design_Fire_Scenarios_for_Railway_Tunnel_Fires. Knowledge of smoke spread and fire development in tunnels is generally obtained from large-scale testing and laboratory testing. The aim is usually to investigate some specific problems such as the influence of different ventilation systems on smoke and temperature distribution along the tunnel, the fire development in different type of vehicles or the heat exposure to the ://
Not all available equipment for fire detection are suitable for road traffic tunnels due to environmental aspects and detection settings (Zalosh and Chantranuwat, ). A tunnel fire will always start with a low heat release rate. Small fires, e.g. a car may reach heat release rates of about 3–5 MW (Ingason, ). To reach these levels of road tunnels, 9 th Int.

Although every tunnel or underground structure is unique, numerous design guidance standards and regulations have been developed around the world to When HGVs are involved in fires, there is a higher risk of the fire developing into a much larger, more serious fire.
The duration of recorded serious fires in road tunnels range from 20 min to 4 days. Most of the serious fires are in the range of 2 to 3 h.

A design fire is defined as a Heat Release Rate (HRR), in MW, as a function of time. It provides the fire characteristics that are used to establish the sizingIn Chapter 4 of the technical report R35 «Experience with significant incidents in road tunnels» new information on fires rates has been compiled, based on tunnel fire statistics from 12 countries around the world.
The collection of data for statistical purposes requires a clear definition of events which should be considered as :// development of vehicle fires, based on experimental tests. However, for those seeking instant answers to design fires in tunnels, the report delivers some rather sobering conclusions: a universal design fire cannot be specified, because the probability and size of any fire is inherently unknown.

The reasons for this are manifold: Small datasets as well as incomplete or inconsistent datasets – often caused by regionally varying data collection practices – account for some of the challenges.
