Modeling for Operating Expenses and Time Consumption of High-Speed Railway (HSR)

Transportation plays a significant role in each country's economy and it is critically important to ensure its dynamic ha ionious development. Operating expenses and time consumption are important indicators for planning vertical profile of high-speed railway line. The paper presents two models: i) first estimates the effect of stations spacing on operating expenses, and ii) second measures the effect of maximum gradient on time consumption. In this regard, six standard vertical profiles of high-speed railway line have been studied. The results show that operating expenses model is a third-degree function of station spacing, whereas time consumption model is a quadratic function of maximum gradient. Further lore, it is determined that station spacing has great impact on operating expenses and time consumption of HSR.
