No-notice emergency mass evacuations are preplanned based on flow-controlled mobility of prioritized vehicles and pedestrians on high volume conditions. The bidirectional computerized telecommunications in real time allow the surveillance of minimum time headways between mass transportation vehicles, and the observation of social distance among pedestrians. Flow control increases the safety on mass mobilizations. For example, a total evacuation from UTSA downtown campus in 15 minutes peak period (1,134 occupants, and 761 automobiles). The evacuation of occupants is achieved by creation of transit mode corridors because in a densely populated area such as the central business district of a city like San Antonio, transportation and pedestrian demand may exceed the network capacity. A hypothetical no-notice mass emergency evacuation on UTSA Downtown Campus based on field data collected is explained, achieving a total mass evacuation out of the risk area within a 15 minutes time limit. The pre-plan is a multidimensional, multidisciplinary and multimode task, based on utilization of nearby available resources including bidirectional telecommunications.
