| 摘 要： | 地铁交通快捷特征的指标——发车间隔和旅行速度并未达到令人满意的程度,在地面交通快速化之后能否保持优势值得关注.它们受到信号闭塞关系的制约,还涉及车辆、线路、供电和运营等专业,影响各有不同.通过两项指标的计算数值,说明系统设计和运营操作中提升指标的落脚点.

| Abstract: | Current indices of departure intervals and travel speeds which both feature the rapidness of metro are not satisfactory and should be noticed while surface communication is speeding up. These indices are dominated by signaling block relation, and are dependent upon rolling stock, track, power supply and operation to a different extent. The author calculated these two indices, analyzed how they were restricted by the metro transit capability and explained the key points to upgrade the indices in system design and operation. |
