Operational performance and profitability of network-wide integrated timetables
Final Report Abstract
Within this project, a methodology was developed for investigating technical, operational and economic interrelationships within integrated periodic timetables (IPT). The methodology is regarded as suitable for various networks, infrastructures and economic conditions. Infrastructure requirements associated with newly introduced IPTs have been derived by constructing timetables and by usage of analytical methods for railway capacity assessment. Requirements specified for one IPT reference case are adapted according to sub-models. As an outcome, high-performing, IPT coherent railway infrastructures were designed. Subsequently, stability of developed timetable concepts was analyzed by railway operation simulations. Evaluation for this operation process data was laid on passenger-relevant delay parameters. The economic evaluation of IPT concepts was focused on changes of the train offer, regarded as particularly demand-relevant, such as shortening of travel times, rise in train frequency and changes in ticket prices / costs. Demand relevance of train delays was also modeled. Overall changes in demand was assessed by referring to demand elasticities. Three possible demand scenarios have been developed. Evaluation of demand reactivity resulting from ticket price changes was connected to ticket price models. By regarding price models, influence of different ticket pricing strategies on fare revenues was revealed. Cost calculation for specific train operations and lines was based on cost-generating factors of the timetable offered, such as vehicle characteristics, travel times, stop and turnaround times including delays, speeds or distances covered. These factors were then allocated to cost parameters. Cost calculation includes infrastructure, vehicle and personal costs as well as overhead expenses. Three cost paths have been modelized: Constant, rising and falling costs. By comparing total costs with modelized revenues, business results are shown. The methodology’s applicability was demonstrated by using a generic railway sub-network. The insights gained are highly relevant for real-world IPT implementations.
