In this paper a traffic assignment model is specified in road emergency conditions. The proposed model takes into account two classes of users: some users in emergency conditions repeat the same choice made in ordinary conditions, some others make a different choice. The basic concept for the proposed model is derived from day-to-day models. The path choice model, which is inside the traffic assignment model, has to take into account three types of information which influence users’ choices: historical information related to network experience in ordinary conditions, real time information related to the current emergency situation, and users’ forecasting of the network evolution based on current experience. A non-equilibrium dynamic model is adopted in order to simulate path flows on the network. A review of static and dynamic traffic assignment models in emergency conditions is reported.

Abstract

In this paper a traffic assignment model is specified in road emergency conditions. The proposed model takes into account two classes of users: some users in emergency conditions repeat the same choice made in ordinary conditions, some others make a different choice. The basic concept for the proposed model is derived from day-to-day models. The path choice model, which is inside the traffic assignment model, has to take into account three types of information which influence users’ choices: historical information related to network experience in ordinary conditions, real time information related to the current emergency situation, and users’ forecasting of the network evolution based on current experience. A non-equilibrium dynamic model is adopted in order to simulate path flows on the network. A review of static and dynamic traffic assignment models in emergency conditions is reported.
