%X The traffic demand after effects of the emergency was divided into two parts: fixed demand and variable demand. One was the evacuation demand and the other was the original traffic demand in non hazardous areas. A system optimal model of evacuation route selection based on partial variable demand was proposed aimed at minimizing the total travel time of traffic network system. The equivalence between the solution of the model and the system optimal condition of varying demand was proved. And the existence and uniqueness of the solution of the model was analyzed. At last an algorithm of the model was designed from the convex combination method.
