En granskning av information över tågförseningar år 2012


The purpose of this report is to document the quality of data from the Swedish Transport Administration regarding train delays, in order to assess whether it can be used to deepen the understanding of the size of the delays and the conditions that generate delays. In order to limit the work we have only considered quarter 1 of year 2012. The overall impression is that the quality of the data has become much better. It is not obvious whether this is due to better reporting/insertion of data or if new methods to extract data from existing systems have been developed. It is also important to emphasize that with the increased knowledge of the data the possibilities to deal with some ambiguities that we earlier saw as inaccuracies in the material have increased. Our hope is that with data from year 2013 and onwards it should be possible to perform structured analyses of delays in the whole rail network in Sweden. As a first step towards analysing patterns of delays in the rail traffic we have presented a description of the delay pattern on the so called “Dalabanan”, i.e. the traffic between Mora/Falun/Borlänge and Stockholm, and also at “Uppsala-pendeln” between Uppsala and Stockholm.

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.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...


New climate-proof solutions for hard surfaces in cities

High-density road infrastructure that emphasise maximum durability and minimum maintenance create inflexible systems, which put increased stress on urban trees and lead to increased risk for flooding. Over the past five years, the ‘Climate-proof solutions for...


VTI is preparing for automated vehicles

Automation of traffic systems will lead to major changes. The European Union’s (EU) CoEXist research project began in June 2017 with the aim of preparing cities and road operators for the introduction of self-driving vehicles. The Swedish National Road and...


Vehicle Driver Monitoring: sleepiness and cognitive load

To prevent road crashes it is important to understand driver related contributing factors, which have been suggested to be the critical reason in 94 per cent of crashes. The overall aim of the project Vehicle Driver Monitoring has been to advance the...
