Optimization Model of Transit Route Fleet Size Considering Multi Vehicle Type

This paper proposes a bus line capacity optimization design model considering the scale of multiple vehicles, which is achieved by minimizing system operating costs and user costs. The proposed takes into account difference passenger demand in different periods, can get optimal headway delivery reserve plan. In order to prove that method effectively minimize cost, we solved numerical example compared cost multi-transit planning. Furthermore, results show total (TC) were reduced 14.48%. Among them, (UC) decreased 30.38% operator (OC) increased 4.18%. Sensitivity analyses are presented verify validity model. analysis multi size reduce especially certain weight interval. Besides this, reflects volume waiting time value, optional cross-section all affect vehicle scheme cost.
