Impact assessment method to forecast high speed railways punctuality due to technology evolution

Dies ist die aktuellste Version dieses Eintrags.

Kurzfassung

Delayed trains not only cause passenger annoyance, but also lead to a significant overall delay of the passenger to his or her destination. Especially in high-speed railway, delayed trains can cause a significant overall delay of the passenger due to missed connections. This can have a high negative impact on passenger satisfaction and consequently on the modal split. In high-speed rail systems, a large number of delay minutes are caused by technical failures. Investments in cost-intensive technical innovations are a fruitful method in order to eliminate these technical failures. But to estimate the impact of technical innovations on the punctuality of high-speed trains, microscopic simulations are often needed to be carried out using a huge number of technical and operational details as input and thus increasing the complexity, cost and computer capacity for this task. For this reason, a simplified methodology is necessary in order to provide a first orientation on the impact of technical developments on punctuality. Such a methodology has been developed and applied in the IMPACT-2 project of the Shift2Rail (S2R) initiative to assess the impact of significant technical developments on rail operations in a modernised European high-speed rail system. The objective of this research is to provide a simplified approach for decision makers in the railway sector to assess the expected impact of proposed and planned technical innovations on punctuality after their implementation.
