A BEHAVIOURAL‐BASED SIMULATION MODEL FOR URBAN EVACUATION

Abstract

ABSTRACT Several radiological and industrial incidents which occurred during the lust decade refocussed the attention of various authorities to evacuation preparedness and consequently, elaborate network simulation models have been developed. The modellers, however, recognise that critical variables relating to behaviorual aspects of the evacuees are still missing. This study presents a microlevel simulation model for radiological evacuation which incorporates such behavioural input. Using the SLAM II language to develop a network algorithm, the model estimates network clearance lime for two scenarios — early evening and late night, and the role of the behavioural data is examined. The model can he used to lest traffic management schemes for emergency evacuations much more realistically than the purely engineering‐type models.
