研究目的:地铁行人通道宽度设计直接决定通道的服务水平和流通效率,为使设计的地铁通道宽度满足给定的服务水平和需求的波动性,本文在考虑客流到达、服务的随机性和状态相关性的基础上,建立描述通道排队现象的状态相关排队模型及基于该模型的服务水平和通道宽度的量化关联模型,以供地铁车站合理设计行人通道宽度。研究结论:(1)通过模型与微观仿真验证,本文以准生灭过程建立的的PH状态相关排队模型,可以准确描述通道排队现象;(2)基于PH状态相关排队模型的通道有效宽度量化值较其他排队模型计算值有所提高;(3)在PH状态相关排队模型设计宽度下得到的真实人均面积与设计服务水平最接近,而其他模型的计算值均无法满足设计服务水平;(4)本研究成果对真实有效描述地铁通道排队现象,地铁车站规划设计与运营管理具有重要意义。
Research purposes: The width ofsubway footwaydetermines the level of service and the efficiency of circulation. To meet the given level of service and the demand of volatility, a queuing model considering the randomness and state - dependence of the passenger arrival and serviceis established to describe the footway queuing phenomenon, andthenthe quantitative association model between the level of service and footway width is developedtodesign the rational width of subwayfootway. Research conclusions:( 1 ) According to the micro -simulation validation, the PH queuing model based on quasi birth and death processes can accurately describe footway queuingphenomenon. (2)The design width based on the PH queuing model is larger than that of other queuing models. (3)The real area per person under the design width based on the PH queuing model is closest to the design level of service, while the results based on other models are all unable to meet that. (4) The research result is of great significance for a real and effective description of the footway queuing phenomenon and for planning and operation of subway station.
