Emergency evacuation in large traffic facilities has been important issues of social security. Current evacuation models less consider the situation, which many passengers carry luggage in large transportation hub. This paper proposes a new cellular automation model according to characteristics of luggage. The distance parameter, spatial parameter, empty parameter, obstruction parameter, luggage following rules and new route created rules are introduced in the model. This paper mainly analyzed the effects of carrying or leaving luggage on evacuated pedestrian flow. Evacuation time is verified based on the simulation under the different space occupancy and different ratio of pedestrian with luggage. The article takes a waiting area in railway station as an example to simulate. The result shows that if moving with luggage, as the initial space occupancy grows, the increase of the proportion of people with luggage has more obvious impact on increase of evacuation time; Besides, when pedestrian space occupancy surpass 60% and the ratio of pedestrian with luggage exceed 50%, due to abandoned luggage loss of mobility, the effect of hindering the subsequent pedestrian movement become stronger. Carrying luggage rather than leaving luggage may make overall evacuation time shorter.
