The methods for emergency traffic organization under abnormal state are put forward both on macroscopical and microcosmic aspects. It tends to study the strategies on the macroscopical aspect and tends to study the techniques on the microcosmic aspect. In the end, there is a forecasting and conceiving of the future development of emergency traffic organization.
