Knapphet på järnväg: sammanställning av två promemorior

Mats Andersson

The use of market mechanisms for timetabling of trains is discussed in three different time perspectives in the report. Motives for charging for booking and de-registering trains in the upcoming time table is discussed, too. The point of departure is that a substantial number of trains in a timetable are never operated.

Three different time perspectives on the basic timetabling problem are discussed. The short term approach would be to use a bidding mechanism for solving remaining conflicts. It is suggested that a one shot, sealed bid second price procedure is developed. This means that bids from the two or more bidders for each conflict are submitted once and for all and that the highest bidder pays a price which equals the second highest bid. There are strong reasons to believe that this would work to guarantee a truth-revealing process resulting in an efficient allocation.

It is further recommended that posted prices for use of bottlenecks is developed in the medium term. In the long run, it is necessary to develop an optimization algorithm which is capable to solve the computationally challenging problem of establish a value maximizing solution to the allocation of competing demands for track access. As a complement, a mechanism for efficient bidding needs to be developed in order to provide incentives for operators to participate in the process with truth revealing bids.

The point of departure for the second document is that a substantial number of (freight) trains in a timetable are never operated. The reason may be that the service provider’s ex ante estimates of demand may turn out to be wrong, i.e. that actual demand is lower than the initial estimate. There is a simultaneous pressure for new slots which emerges after that a time table has been established. The document makes suggestions for a system of reservation charges and charges for cancelling trains on short notice.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.



Modal shift for an environmental lift?

Investigations in Sweden and other countries suggest a shift of goods transport from road to rail and waterborne transport to reach environmental and climate objectives. VTI is leading a new project to investigate how the modal shift can contribute and what...


Automation and digitalisation are making rail competitive

Road transport is developing rapidly and its productivity has increased sharply. Rail transport, however, has not developed at the same rate. Automation and digitalisation are essential if rail freight in Europe is to survive.


New research is creating a driverless logistics chain

The research project Born to Drive has come up with a system that allows new cars to move, without a driver, from the production line out to the parking area prior to being transported elsewhere. The vision is to automate the entire logistics chain from...


VTI testing automation in EU project

VTI is leading a series of tests in a major EU project on automated driving. The first driving tests were carried out n a test track in Slovenia in December. The project will focus in part on acceptance among different groups in society, in part on...


Freight transportation on road and rail analysed

Freight transport accounts for a large proportion of the emissions, noise and congestion produced by road traffic. Transporting freight in larger but fewer lorries could reduce the problem. At the same time it might entail freight being diverted from more...


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...
