A large variety of models and procedures for road transpoitation system analysis exists in literature. The paper presents a comparison among different modelling approaches (pseudo dynamic, mcsoscop~c, microscopic) for the simulation of a road urban transportation system in emergency conditions. Pseudo dynamic approach (derived frotn user equ~libriurn) can consider stochastic or deterministic user behaviour in path choice and is able to provide average values concerning traffic conditions. The nlesoscopic represents traffic conditions on the network analysing groups of drrvers having homogeneous behaviours, called "packets". It provides results consistent with each packet.
