Stochastic programming is used to identify optimal allocations of emergency response teams on the freeway. Previous studies used the probability of incidents, considering all incidents equal and ignoring scenarios in which two incidents occurred within proximal regions and intervals. In this study, first stage decisions are made before a realization of uncertainty of primary incidents. The recourse in the second stage includes excessive response to secondary incidents, using multistate mixture model to present distribution of excessive response time due to the negative impact of an incident.
