| Abstract: | In order to study the influence of companion behavior and presence of obstacles on the evacuation process,a cellular automata evacuation model of double-exit considering two-person companion behavior was established.The risk degree was introduced into the static field to simulate the route selection of pedestrian,then the evacuation processes under different pedestrian densities were studied by setting individual and two-person companion evacuation crowd,and the evacuation efficiencies were compared.The pedestrian processes under different proportions of companion were simulated with the same density,and the optimal proportion was obtained.Three kinds of arrangement mode of obstacles were set,including the horizontal arrangement,vertical arrangement and horizontal-vertical arrangement,and the best arrangement of obstacles was obtained by simulating two evacuation situations of individual evacuation and companion evacuation.The results showed that for the individual evacuation and companion evacuation,the evacuation time increased with the increase of pedestrian density,and the individual evacuation was better than the companion evacuation under the same pedestrian density.Under the same proportion of companion,the pedestrian evacuation time increased with the increase of pedestrian density,and the evacuation efficiency was higher when the proportion of companion was less than 0.6.The best arrangement mode of obstacles was horizontal-vertical arrangement,and the recommended companion pedestrian proportion was 0.4. |
