Tidtabelläggning: principer, tumregler och utfall


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.



Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.
