Description
Swiss guidelines require new or refitted road tunnels be equipped with two systems for fire detection, namely temperature analysis and smoke analysis. The smoke analysis shall differentiate between a moving and a stationary smoke source. This requirement has led to the development of sophisticated algorithms, which are now widely employed in Swiss road tunnels.
Many tunnels can be modelled as single tubes. But branching tunnels need to be covered as well. These scenarios are more complex and pose difficulties to the smoke analysis.
This paper presents the challenges faced when trying to implement smoke analysis within a tunnel with significant branching.
