Different speeds for different drivers – on the same stretch of road

Traffic backups can be reduced by new traffic systems in which each vehicle is given an individual speed limit. The major challenge is to get everyone to agree to such a system. VTI is now demonstrating the benefits of new information sources by co-authoring a recently published book.



Correlations between laboratory dynamic CBR and compaction parameters of unbound coarse...

It is well known that the determination of fundamental engineering properties of materials is the key to their inclusion within quality control assessments and pavement design. Although using of maximum dry density and optimum moisture content has...

The effects of information relevancy on driving behavior: A simulator study on...

Bus driving is a complex and cognitively challenging task that places high demands on bus drivers’ working memory. Increasing use of “In-Vehicle Information Systems” leads to driver distraction and is a contributing factor to many road accidents...

Flexibility in contract design: is that possible?

Public procurement is widely used in order to incorporate competition into public services. Competition in procurement often leads to efficiency but the process can also raise some problems. While providing the procurement documents you do not know...

Evolution Road – new electric road tested both inside and out

In the beginning of May, the next-generation electric road was inaugurated in the city of Lund in southern Sweden. Ground based conductive charging technology will be tested on a kilometre long stretch of electric road in the bus lane in Getingevägen. This...


Additional policy instruments are needed to achieve Swedish environmental quality objectives for maritime transport

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...


Opportunities for a new market in electrified regional flight

Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.


Need for standards as electric road systems are developed

The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...


Unique knowledge compilation on microplastics from road traffic

Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).


Measures for infrastructure climate adaptation requires prioritisation

The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...
