Description

In view of the high population density in the urban areas of many large cities in China and HongKong, there is a great demand for mass transportation service in such cities. Mass transit rail is akey part of modern cities’ transportation system. The rail and stations are an integral part ofmetropolitan people’s daily life. The stations will have a great variety of usages such as shops,banks, fast food kiosks, exhibitions and etc. Passengers moving in the stations may not only headtowards the train but also commit other activities. Huge volume of passengers will use the masstransit system every day in Hong Kong, Shanghai or Beijing and the stations become crowded inmost time of a day. Though most of the modern metro facilities are provided with noncombustiblematerials, passengers, especially those in the terminal stations, may carry baggageand other things that may be combustible. Ignition of carry-on packages causing serious fire didhappen in Hong Kong and other countries, such as the fire incident in January 2004 in a metroline in Hong Kong. Fire risk associate with the fire loading carried by the passengers haveseldom studied. One of the difficulties in studying such passenger-carried fire load is its dynamicnature. To study such dynamic passenger-carried fire load, we need to study in detail thepassenger movement pattern in stations. Computer models that can simulate the movement andactivities of the passengers will be an integral part of the study. Here we aim to establish aneffective simulation model to study the dynamic passenger-carried fire load for metro and railsystem. The model will be a microscopic simulation model which can mimic the movementpattern of an individual passenger and comprehensive site survey for passenger-carried fire loadwill be performed. The study will include 3 major parts: (i) to collect field data on passengermovement characteristics and carry-on baggage fire loading; (ii) to establish dynamic passenger-carriedfire load simulation model on the basis of an agent-based passenger flow model; and (iii)to develop a dynamic passenger associated fire risk model for metro stations.
