The Optimization of Urban Rail Transit's Train Operation Plan in Non-Peak Period Based on Coordinated Transfer

In recent years, with the accelerating process of urbanization, urban rail transit have been rapidly developing in China's megacities. From the experience of construction and operation of rail transit in our country at this stage, the transfer behavior between lines accounts for a great proportion in the total trip amount undertaken by rail transit due to the limitations of rail network coverage. Meanwhile, the consideration of coordinated transfer is comparatively insufficient. In this paper, In response to the characteristics of urban rail transit's transfer, and taken the convenience of the transfer between lines into consideration, the train operation plan of rail transit in non-peak period is optimized targeting on minimum cost of system transfer. And the optimization model of rail transit's train operation plan in non-peak period is obtained by proposing the computing method of total transfer cost. After checking the validity of the model, the new optimized train operation plan shows significant reduce of passenger's transfer time in non-peak period. The study can be used as reference to the optimization of train operation plan.
