Optimal Traffic Planning for Efficient Evacuation
2016
Journal of Advanced College of Engineering and Management
Preserved Fulltext
<p>Efficient traffic planning during evacuation in emergency has been important issue. The planning based on research significantly improves the quality of the emergency management. ...
In this paper, we discuss on both optimization and simulation approaches of the traffic planning. Both approaches have been extensively studied in the literature with efficient softwares. ...
The traffic planning can be made efficient if it is based either on optimization approach or on the simulation one. There have been several procedures depending on the situation of the evacuation. ...
