Dynamic convergence module, it is used for during crowd evacuation, and group member completes group based on double-deck social force model
Convergence, is responsible for leading group member to evacuate by leading；Consider that discrete pedestrian and its group psychology come real during evacuation simultaneously
Existing its is converged to the dynamic of group；
Wherein, in the dynamic convergence module, it is considered to which discrete pedestrian and its group psychology realize that its is converged to the dynamic of group
Process be：
The artificial P of default discrete linesi；The safe distance L of discrete pedestrians；The direction of motion of current point in time group is εγ(τ)；It is discrete
The target group of pedestrian's convergence is P；Coalescence rate is vi；Then：
Calculate discrete pedestrian PiL and visual angle deviation angle θ the distance between is led with each group；
Work as l<=LsWhen, calculate discrete pedestrian PiThe direction ε towards groupι(τ)；
If (| θ | ＜=5 °) ＆＆ (ει(τ)=- εγ(τ)), then final discrete pedestrian PiIt is its convergence to take closest group P
Target group, and final coalescence rate is：
