  7. Abstract:
  8. Natural disasters have been with the earth, and felt critical as far back as human history. These incidents are inevitable, but their effects may be controlled. One important problem after a disastrous earthquake is the management of people’s vehicular movements in a chaotic situation. This study is an endeavor to envisage what would possibly happen after such an incident, and how could we possibly control or manage the traffic in such an occasion. We start with the analysis of the online reports of similar past incidents, and try to picture how people react to these events. We try to identify the trip purposes that have been shown to be pursued, and the respective origins and destinations. The most important trip purposes in such instances are those of the relief operations. A multi-level programming problem is defined to model the operations (trips) of the several groups involved in such operations: Those involved in reopening the roadways, rescuing people from the collapsed buildings, assignment of ambulances to the demand scenes, and transporting the injured and the incident victims to the hospitals and recovery places. The whole operations are programmed to minimize the death tolls. This problem is solved under a base scenario, and compared its results with the respective ones under other trip management scenarios to control the trips originated from the general public. The results in a test network show that certain general public trip management may increase the efficiency of the relief operation by 25%
