Abstract:

The evergrowing passengers of urban rail transit have resulted in a great difficulty for operation. The principal measures for improving transport capacity are analyzed. The potential in improving transport capacity is insignificant for Beijing Metro Line 1 via increasing marshalling coach numbers or declining headways. An unconventional train travel pattern naming train-inserting scheme is presented to improve the transport capacity of Beijing Metro Line 1. The scheme may increase the transport capacity by 10% and decrease the ridership from 120% to 110% during the morning peak period. In view of the practical test, the inserted trains are capable of reducing detained passengers on the platform strikingly. The good implementation might provide ideas and experience for the transport capacity excavation of other metro lines.
