Departmental Papers (ESE)


The transporting capacities of diff­erent transit modes are often discussed, but values quoted for different modes vary widely because of differing assump­tions. This paper presents the basic theory of capacity and gives explanation of and insight to three aspects which must be carefully considered in capacity analysis:

  1. Way capacity and station capacity of transit modes usually vary greatly;
  2. Capacity must be considered together' with service quality, primarily oper­ating safety and speed; and

  3. There is a considerable difference b-tween theoretical and practical ·capacities of modes: the latter are important for design.·
