Road tunnel systems are complex environments where the fire risk is generally high and a large number of people might be involved in an emergency evacuation. The purpose of this paper is to illustrate the use of evacuation modelling (and MassMotion specifically) to estimate the Required Safe Egress Time (RSET) for one-way and bidirectional road tunnels having lengths in the range 500-3000 meters. This initial study focuses on tunnels which are considered to be designed in compliance with current safety standards. Plausible worst case for fire locations are considered: additionally, the availability of escape exits in the vicinity of the fire is a key variable of the investigation.
