6、time when emergency events occur. This paper chooses the underground passages of one metro in Istanbul, Turkey as research object, and uses a study method which combines by sites investigation, field test and computer

7、simulation of the creating new software. It is called Building Evacuate Module software. We present a depth analysis of the related factors which include the number and width of passage, channelization set- ting and th

8、e number of pedestrians with the evacuation time. And the influential effect of public opinion is explained by using big data technology. In addition, pedestrians evacuation condition are recorded in three evacuation p

9、eriod, the morning peak, common and evening peak by the ob- servation and statistic obtained with video, and build the model to simulate the change of evacua- tion time with pedestrians. So it reveals when the number of

10、pedestrians reaches to more than 200, evacuation time increases significantly and the field experiment and simulation condition are consistent basically. Keywords Transport Planning, Building Evacuate Module, Crowd Eva

12、ver, the study of the aspect is not so much, of which the relevant theoretical basis is still relatively weak, even is very difficult [1] [2]. Therefore, the ?. Erkan, H. Hastemoglu 3 Figure 1. Simulation scenario of fo

14、 s, however, when the width increases to 6 m, evacuation time is 396 s. This means that when the width of evacuation exit multiplies, evacuation time doesn’t decrease in equal proportion, but need more time. Therefore,

15、 the exit width of the building facilities should be set rationally ac- cording to the need of venues. 2.3. Passages Canalization Setting Evacuation speed and the interference among pedestrians can be influenced by the w

16、idth and the number of evacuating exits; in addition, the reasonable passage canalization set also can increase pedestrians’ evacuation efficiency. Stimulating a situation that the evacuation door width is 1 m, and the

17、 number of evacuation is 100 people, and with a velocity of 1.2 m/s. We set up four kinds of circumstances, in which pedestrian evacuate re- spectively on their own, one passage canalization being set, two passage canal

18、ization being set, and three pas- sage canalization being set Figure 4. shows that when the emergency evacuation happen, setting effective channelized diversion objects at the entrances and exits, can reduce the evacuat

19、ion conflict among pedestrians and also can increase the speed and evacuation order, in order to improve the efficiency and safety. When too many channelized objects are set up in evacuating exits, it will go too far a

20、nd the evacuation effi- ciency will be reduced. 2.4. The Number of Pedestrians The number of pedestrians is also an important factor. In this case, we assume 50, 100, 150, 200, 250, 300 peo- ple separately are evacuated

21、at 1.2 m/s , across the underground passage with length of 20 meter and the width of 2 meter. And the scenario of evacuation simulation is shown in Figure 5 at Building Evacuate Module (BEM). The relation of number of

22、 pedestrians and evacuation time in Figure 6. Figure 6 shows that the evacuation time is rising with the number of pedestrians increasing. However, the trend graph indicates that the value of evacuation time is not inc
