Research on Turn-back Scheme and Capacity Improvement Based on Typical Station

In view of the problem of mismatch between the transportation capacity demand and the transportation volume in the operation of urban rail transit, to meet the demand of high-density traffic organization, to relieve the operation pressure, a line capacity improvement scheme is studied, which is a flexible combination of receiving and departure sequence by adjusting the controllable operation time of the train at the turn-back station, without changing the original civil wiring, as well as the safety protection and block design of the signal system. Taking a typical station of Shanghai rail transit as an example, analysis and study are conducted, and further suggestions on traffic organization are delivered.
