Application and Research of Virtual Reality in Metro Station Safety System and Fire Simulation

Several severe accidents have occurred in metro transportation, the attention for safety has increased enormously. The paper introduces the method to combine metro traffic safety with Virtual Reality technology in urban rail traffic system, studies the metro fire characteristics and causes. Puts forward a method to set up the metro virtual environment for simulation by using Virtual Reality technology, which is helpful to deal with potential hazards in advance. On this foundation, by using 3DS MAX and OpenGL graphics programming techniques, the rendering pipeline of virtual metro station scene is designed. The virtual metro station scene is rendered and can be roamed and implemented in real time. The dynamical fire effect is rendered in the virtual metro station by using the real time fire simulation algorithm based on the particle system, and the locomotive and metro station fire are simulated. Preliminary fire simulation framework of the virtual metro station is established.
