Short description:
A sequential dynamic choice model to simulate demand in evacuation conditions / Russo, F., Chilà, G.. - 43:(2010), pp. PI-431-PI-442. [10.2495/RISK100371]
abstract:
When a dangerous event occurs, a variety of events affects the system
characteristics of users and of the transportation network in the time. Dynamic
models allow us to simulate variation in choice probability from one time to
another, considering temporal evolution of user characteristics and of dangerous
event. Among dynamic models, sequential dynamic discrete choice models
represent a special class and are proposed in this work to simulate evacuation
conditions. Sequential tests are introduced to validate the proposed model and in
order to ascertain whether current decisions are directly influenced by the most
recent previous decisions. Sequential tests are specified for evacuation condition
simulation and allow us to assess the significance of the reduction in uncertainty
