Pedestria. eva.ua.ion is a.tua.ly a.process of beha.iora. evolution. Intera.tion beha.iors between pedestria.s a.fect not only the evolution of their coopera.ion stra.egy, but a.so their eva.ua.ion pa.hs-scheduling a.d dyna.ics fea.ures. The existence of intera.tion beha.iors a.d coopera.ion evolution is therefore critica. for pedestria. eva.ua.ion. To a.dress this issue, a. extended cellula. a.toma.on(Ca. eva.ua.ion model considering the effects of intera.tion beha.iors a.d coopera.ion evolution is proposed here. The influence mecha.ism of the environment fa.tor a.d intera.tion beha.iors between neighbors on the decision-ma.ing of one pedestria. to pa.h scheduling is focused. a.era.e pa.offs intera.ting with neighbors a.e used to represent the competitive a.ility of one pedestria., a.ming to solve the conflicts when more tha. one pedestria. competes for the sa.e position ba.ed on a.new method. Influences of intera.tion beha.iors, the pa.ic degree a.d the conflict cost on the eva.ua.ion dyna.ics a.d coopera.ion evolution of pedestria.s a.e discussed.

The increa.e of conflict cost prolongs the eva.ua.ion time.
