Problems solved by technology
[0004] The selection of the target door and the moving path during the evacuation process will directly affect the overall evacuation efficiency. However, it is difficult to simulate the actual evacuation of passengers in the subway car accident. Currently, on-site Data collection and actual survey work are very costly in terms of manpower, material resources and time, so research in this area is a very important task

Embodiment Construction
[0046] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0047] Such as figure 1 with figure 2 As shown, the evacuation prediction method of passengers in the urban rail transit subway car includes the following steps:
[0048] S1), based on the fuzzy logic theory, the target door selection model is constructed when passengers evacuate out of the subway car, and the probability value of passenger selection for each door is calculated and obtained;
[0049] S2), based on the cellular automata model, combined with the passenger's own psychological behavior characteristics, calculate the passenger's movement probability value in real time, and establish a movement model for passengers to evacuate from the subway car;
[0050] S3), using the constructed passenger target door selection model and moving model to carry out simulation experiments, simulate the evacuation of passengers...

The invention provides an evacuation prediction method for passengers in urban rail transit subway carriages, which comprises the following steps: 1) constructing a target vehicle door selection model when the passengers evacuate out of the subway carriages on the basis of a fuzzy logic theory, and calculating to obtain a probability value of each vehicle door selected by the passengers; 2) based on a cellular automaton model, calculating a movement probability value of the passenger in real time by combining the psychological behavior characteristics of the passenger, and establishing a movement model of evacuating the passenger out of the subway carriage; and 3) carrying out a simulation experiment by adopting the constructed passenger target vehicle door selection model and the movement model, simulating the evacuation condition of passengers in the subway carriage, and predicting the influence of the accident point position, the effective utilization width of the carriage vehicle door and the arrangement mode of seats in the carriage on the passenger evacuation when the subway carriage has an accident. According to the invention, the evacuation behavior of passengers in the subway carriage under the sudden accident can be effectively predicted, and a certain auxiliary decision support is provided for emergency rapid evacuation of the passengers in the carriage.
Description
technical field [0001] The invention belongs to the technical field of pedestrian safety evacuation, and relates to pedestrian prediction and evacuation, in particular to an evacuation prediction method for passengers in urban rail transit subway cars. Background technique [0002] At present, my country's economy is developing rapidly, the population is increasing, and the demand for public transportation is also increasing. In the case of accelerated new-type urbanization, the traditional urban ground transportation mode can no longer meet people's needs. As an important supplement to the traditional ground transportation system, urban rail transit has become an indispensable part of the national urbanization process. kind of demand. Urban rail transit has become the backbone of urban public transportation due to its large capacity, fast speed, safety and pollution-free technical characteristics. Its development is of great significance for improving the sharing rate of p...
