The experiment and simulation analysis of bus emergency evacuation

In this study the emergency evacuation experiment of electric buses is carried out for three different scenes. From the observation of the experimental procedure it can be found that the evacuation efficiency and speed of wider backdoor are larger than the front door, but the total evacuation time of the back door is more than the front door. At the same time, the experimental results are compared with the simulation results by software STEPS. It shows that it can fit well when the parameter Patient equals 0.7. Using the STEPS to do further simulation, the estimated action time for the scene that the initial 70 passengers evacuating from only front door, is about 2.5 minutes.
