There is often no serious problem with people gathering, but both incomplete facilities and negligence of people security manage may court injury or death. The purpose of this study is to analyze crowded nodes and to improve evacuation path use Simulex models. The fastest and safest way to achieve safe egress was then well planned. For turn locations, it was found that fixing the plane angle did not significantly raise the overall exiting efficiency. However, replacing the right angle or other angles with arc angle makes overall exiting moving line more fluent. For multito single-directional converging T-junction intersections, modification of turn angle increased the movement fluency, with the higher the modified angle, the higher in fluency. However, changing to round angle did not have as significant effect as expected while gate opening width must be increased to 1.0 m before more significant effects were produced. The results showed that modifying turn angles to 60° produces better improvements.展开更多
