| 摘 要： | 现代企业物流已广泛采用即时制运输模式，铁路货运面对多批次轻量化运输服务需求，一贯追求重栽的战略遇到了挑战，需要在输送量、牵引质量、旅行速度、行车密度之间进行权衡。铁路列车交通流特性是寻求最佳配置上述技术参数的基础。给定试验的机车牵引性能曲线，应用模拟模型计算线路上列车运行的空间平均速度，对铁路列车运行的交通流特性进行数值分析。根据数值模拟结果得出列车流量-密度和速度-密度关系曲线。分析结果显示在一定条件下提速不会降低输送量，存在一个最优组合。

| Abstract: | The mode of just in time is widely used in modern firm logistics. The railway are now confronted with the (demand) of more frequency and lighter transport and the challenge for its strategy of heavy loading. When seeking optimal (configuration,) there is a trade-off among transferring quantity; loading, spatial mean speed and density. The simulating (method) is used to analyze characteristics of traffic flow on the railroad. It is shown by numerical result of the relation (quantity-density) and speed-density that to decrease railway loading may not always lead to decline in transferring quantity and there is an optimal combination. |
