Abstract: With the urban rail transit network in Beijing becoming gradually intensive, the passenger flow organization also develops towards the type of the network mode. This paper analyzes the development trend of the urban rail transit network in Beijing. On the basis of a reasonable classification of emergencies occurred in urban rail transit, this paper puts forward the passenger organization model of rail transit network under emergency conditions, and then set a certain train accident of Beijing Metro Line 1 as an example to illustrate the practical application of the passenger emergency organization mode.

Abstract: Keep in pace with the 2008 Beijing Olympics and the 2010 Shanghai Expo, engineering events of different types and sizes are coming to China more than it had ever happened during years. Obviously, these could all cause safety problems. To organize the event perfectly, a lot of questions occur: How to provide the best safety to everyone participate in our event? How to deal with the emergencies during the event? These questions are the most important element of holding a successful event. This paper discusses the necessity of engineering risk management during events. [Copyright &y& Elsevier]

Abstract: To take into account reasonably the safety requirements of the disabled on emergency evacuation in the design, usage, management and emergency response of public places, the authors of this paper organized on-site experiments for 100 disabled individuals (40 people with no supporting tools, 20 people using a single crutch and 40 people two crutches) and 17 healthy people at a subway station in Beijing. The experiments were designed to measure the unimpeded free walking speed of the participants during horizontal and stair ascending/descending movement, and to assess the possible impact of passage width on movement speed. Based on the results of the tests, the authors systematically analyzed the speed variation patterns with disability grade, gender and passage width. The validity of the value of an important parameter for evacuation safety design in the prescribed fire codes in mainland China, the width of a single stream of people, is assessed. Finally the results of the experiments are compared with that from other researches to identify the similarities and differences between them. [Copyright &y& Elsevier]
