Objectives of Modelling Evacuation from Buildings during Accidents: Some Path‐model Scenarios (pages 207-214)

The basic objective of developing an evacuation model is to supply the user with valid and valuable information on which conclusions concerning the safe evacuation from a building can be drawn. Several evacuation models have been developed over the last 15 years. In our opinion, many of these models are too narrowly focused, perhaps not meeting the needs of the decision maker.

This paper discusses the objectives of evacuation studies and the selection of a suitable modelling technique relative to these objectives. We show that many different approaches to evacuation modelling are appropriate for different types of studies. In the discussion about different existing models and solution techniques, we present some of the basic philosophy lying behind the simulation model EVACSIM.

EVACSIM has been developed to meet the need for an evacuation model that can combine knowledge about human behaviour with the ability to perform large‐scale simulations of network processes. EVACSIM treats people as individuals and it has the capacity to collect any information of interest (in principle) regarding their movements, their exposure to potential accident effects and their time to exit the different parts of the structure. The role of an evacuation model in an evacuation analysis is also discussed.
