  This paper develops two types of estimation models to quantify the impacts of carriage crowding level on bus dwell time.The first model(model I)takes the crowding level,number of alighting and boarding passengers into consideration and estimates the alighting time and boarding time respectively.The second model(model Ⅱ)adopts almost the same regression method,except that the impact of crowding on dwell time is neglected.The analysis was conducted along two major bus routes in Harbin,China by collecting 640 groups of dwell times under crowded condition manually.Compared with model Ⅱ,the mean absolute error(MAE)of model I is reduced by 137.51%,which indicates that the accuracy of bus dwell time estimation could be highly improved by introducing carriage crowding level into the model.Meanwhile,the MAE of model I is about 3.9 seconds,which is acceptable in travel time estimation and bus schedule.

传统的交通选择模型采用基于期望效用理论的离散选择模型,但忽略了不确定性条件下人们决策的有限理性特征。本文提出一种基于前景理论的交通方式选择模型,以交通出行时间和出行费用为特性变量设置参考点,建立基于价值函数和决策函数的前景值,并通过Logit 模型对交通出行方式进行预测。本文以清华大学学生出行为例,通过问卷调研获得出行时间和出行经济费用的参考点,利用该模型较为准确地预测了不同交通出行方式的分担率,

随着国家能耗问题逐步严重,"节能减排"成为航空公司的热议话题。本文针对机型指派的能耗问题在时空网络下分别建立了机型指派的成本最小模型,能耗最小模型以及能耗约束下带惩罚系数的成本最小模型。通过求解航空公司的日航班计划,对比分析能耗及成本的影响。研究表明本文提出的能耗约束下的机型指派模型和传统的成本最小模型相比,总成本降低,更佳符合绿色发展的趋势,为航空公司发展节能减排提供良策。
