本文提出了一种基于频率的分配模型，该模型考虑了出行者在路线成本感知中找到座位的概率，从而考虑了他们的路线选择。该模型在登机点引入了一个“没能坐下”的概率，并根据坐着或站着旅行的可能性引入了旅行成本。考虑优先级规则；特别是假设站在机上的乘客会在新登机的乘客占据剩余的座位之前占据所有下车乘客的座位。在登机点，假定乘客是混杂在一起的，这意味着没有观察到先进先出。就像许多拥挤的公交车站和地铁站一样，尤其是在欧洲国家。路径选择考虑了共线问题，通过马尔可夫网络加载过程和逐次平均法寻求用户均衡解。在将该模型应用于伦敦地下网络的内部区域之前，首先用一个小的示例网络进行了说明。举例说明了乘客在寻找座位时可能附加的不同价值观的影响。讨论了该模型在交通规划和出行规划阶段信息提供中的应用。(C) 2010 Elsevier Ltd.版权所有。
This paper proposes a frequency-based assignment model that considers travellers probability of finding a seat in their perception of route cost and hence also their route choice. The model introduces a "fail-to-sit" probability at boarding points with travel costs based on the likelihood of travelling seated or standing. Priority rules are considered; in particular it is assumed that standing on-board passengers will occupy any available seats of alighting passengers before newly boarding passengers can fill any remaining seats. At the boarding point passengers are assumed to mingle, meaning that FIFO is not observed. as is the case for many crowded bus and metro stops, particularly in European countries. The route choice considers the common lines problem and an user equilibrium solution is sought through a Markov type network loading process and the method of successive averages. The model is first illustrated with a small example network before being applied to the inner zone of London's underground network. The effect of different values passengers might attach to finding a seat are illustrated. Applications of the model for transit planning as well as for information provision at the journey planner stage are discussed. (C) 2010 Elsevier Ltd. All rights reserved.
