A new and applicable environmental rating tool for use as a policy tool, called EcoScore, was developed and allows evaluating the environmental impact of road vehicles with different drive trains or u...
System analysis of train operations and track occupancy at railway stations
System analysis train operations track occupancy railway stations
2009/9/29
A system analysis approach is presented for investigation of train operations in railway stations based on network, timetable and train detection data. The estimated blocking times, buffer times and t...
Choice of Frequency and Vehicle Size in Rail Transport Implications for Marginal External Costs
Frequency Vehicle Size Rail Transport Implications Marginal External Costs
2009/9/28
Frequency of services and vehicle size are important policy instruments of railway companies. Extending Mohring’s basic ‘square root model’ for frequencies, we arrive at more general formulations for ...

通过对铁路客运枢纽交通衔接的现状以及存在问题的分析,提出换乘方式匹配度、换乘时间、换乘舒适度以及经济性这4个具体的量化指标,建立模糊关系数据模型,利用主动模糊数据库技术,模糊实现交通衔接合理性的自动判别。
利用日气温观测值计算了青藏铁路沿线7个主要气象站1966-2004年的年冻结与融化指数，分析了这些指数的统计与分布特征，并应用两种趋势检验方法：非参数Mann-Kendall检验法和简单线性回归法分析了这些台站年冻结与融化指数的变化趋势。结果表明，青藏铁路沿线多年平均冻结指数大致分布在95~2300 oC·日之间，多年平均融化指数大致在630~3250 oC·日之间。7个站点的冻结指数均呈减少趋...
城市铁路客运站换乘评价仿真研究
铁路客运站 换乘 评价 仿真
2010/8/23
在城市铁路客运站换乘评价指标体系研究的基础上,利用离散仿真软件Arena建立了换乘仿真模型,开发了旅客生成、信息服务、通道、楼梯、连接设施、检票等功能模块。以汉口火车站为例,建立了仿真模型。通过现状仿真实验,得出换乘水平等级为D。提出汉口火车站换乘改造方案。通过对改造方案的仿真实验,得出换乘水平为B,表明改造方案有助于提高换乘水平。
