Traffic guidance evacuation model under the emergency state in public place

Aims at the traffic guidance and evacuation problems under large public places emergency, to achieve the maximum volume of traffic and shortest evacuation time. Then set up the Bi-level programming of traffic guidance and evacuation and build the OCMPSO based on sort selection to study the Bi-level programming. Finally, simulate the large-scale activity in a Spots Centre. The results show that the model proposed in this paper can evacuate the vehicles under large public places emergency efficiently and safely.
