効率的な運転操作の組合せによる省エネルギー運転曲線の作成

摘要

列車運行におけるエネルギー消費量の低減手法として車両や地上設備の省エネルギー化が考えられるが，多大な費用を要さずに効果が得られる手法としては，運転方法の工夫，いわゆる省エネ運転が挙げられる。これは，列車ダイヤであらかじめ設定された駅間の走行時分(以降，ダイヤ時分と呼ぶ)と列車の最速走行時分との差である余裕時分を活用して運転することで，エネルギー消費量を低減するものである。%One way of reducing the energy consumption of trains is to drive them in an energy-efficient manner. There can be various driving patterns between two adjacent stops, or speed profiles, since there is a gap called the running time supplement between the planned running time set in a timetable and the shortest possible running time of the train. In this study, we have developed an energy-efficient speed profile generator by combining partial energy-oriented dnvmg approaches. We have added this generator to the existing shortest running time calculation software; therefore it is applicable to various vehicles and train route alignment. Numerical experiments show that our profile prepared by the generator provides superior performance compared to the manually prepared ones.
