【摘要】：針對(duì)初始分布非均勻的行人流疏散問題,通過定義行人在行走過程中的方向模糊可視域,充分考慮了行人在方向可視域選擇上的差異性;通過引入出口處行人密度,有效實(shí)現(xiàn)了建筑物內(nèi)初始分布非均勻的行人流動(dòng)態(tài)疏散演化過程;通過定義和標(biāo)準(zhǔn)化處理影響轉(zhuǎn)移概率的因素,改進(jìn)了場(chǎng)域元胞自動(dòng)機(jī)模型,并將仿真結(jié)果與相關(guān)已知模型做了對(duì)比分析,研究結(jié)果表明,改進(jìn)模型避免了對(duì)影響轉(zhuǎn)移概率相關(guān)因素的權(quán)重依賴;系統(tǒng)疏散時(shí)間與方向模糊可視域和出口處行人分布區(qū)域大小有關(guān);如果行人在疏散過程中擁有一個(gè)較大的視野,系統(tǒng)能夠在出口處適中區(qū)域內(nèi)通過電子屏、語音提示等方式實(shí)時(shí)提供行人密度,就能夠有效提高整個(gè)系統(tǒng)的疏散效率.
[Abstract]:Aiming at the pedestrian flow evacuation problem with inhomogeneous initial distribution, the discrepancy of pedestrians in the direction visual domain selection is fully considered by defining the direction fuzzy horizon of pedestrians in the walking process. By introducing the pedestrian density at the exit, the dynamic evacuation evolution process of the inhomogeneous initial distribution of pedestrian flow in the building is realized effectively. The factors affecting the transfer probability are defined and standardized, and the field cellular automaton model is improved, and the simulation results are compared with the related models. The results show that the improved model avoids the weight dependence on the related factors affecting the transfer probability, the blurred horizon of the system and the pedestrians at the exit. If the pedestrian has a large field of vision in the evacuation process, the system can provide the pedestrian density in real time through the electronic screen and voice prompt in the moderate area of the exit, which can effectively improve the efficiency of the evacuation of the whole system.
