Tidtabelläggning: principer, tumregler och utfall

Download

The Swedish Transport Agency (Transportstyrelsen) has commissioned VTI to assist in deepening the understanding of the way in which existing railway infrastructure can be efficiently used. The assignment also includes giving advice to the agency’s regulatory tasks within the railway industry. This includes the oversight of the process from initial applications of train paths submitted by train operators to the The Swedish Traffic Agency’s (Trafikverket) subsequent decision about a train plan for the upcoming year and also the ad hoc process taking place from this time to each day of the timetable.

The report comprises three separate mimeos. The first details the principles and rules-of-thumb used during the scheduling process. The second memorandum focuses one particular aspect of the conflicts in demand for track access, namely the need for access to the infrastructure for maintenance purposes and the consequent need to close down tracks for train operations during this period of time. The third and final mimeo seeks to assess the outcome of the process. In particular, a comparison is made between applications and final allocation of time table slots. Two measures of excess demand are used; the number of trains completely denied access and the adjustment of departure-arrival times relative to initial demand specification.
