Rekommendationer för funktionell utformning av spårvägssystem


Trams are not a common feature in Sweden, which leads to some uncertainty about how they work in an urban environment alongside other transport segments. Trams can take many forms, from the classic trams that use the same lanes as cars, to express trams with their own fenced-off embankments, with higher speeds and possibly some form of signal safety system. The purpose of the project is to formulate recommendations for the design and function of new tram systems or changes to existing systems. The goal is to create clearer, more uniform conditions, allowing for good planning and construction outcomes from the beginning and avoiding subsequent costly changes.

The results presented in this report are based on both national and international experiences of different tram systems. Different cities have different conditions, for example in terms of traffic, population and land, which means that the tram systems need to be planned and built in different ways. Technical solutions such as track designs, curve radiuses, signal systems etc. therefore differ from one tram system to the next. However, the design of the system must guarantee rigorous safety and good efficiency for passengers, staff, and persons and vehicles near or crossing the tracks. The tram system, like all traffic environments, must be clear, simple, predictable and easy to understand.

A driving licence withdrawal can have major consequences in everyday life

A withdrawn driving licence can have negative consequences for a person’s ability to shape their own life. A study from VTI investigates how individuals with visual field loss have been affected by no longer being permitted to drive.


Measuring sleepiness – a challenge for researchers

Driver fatigue has been a research area at VTI for several years, and the researchers have studied various aspects such as the working hours of professional drivers, driver behaviour, accident risks, and the design of warning systems. They are now moving...


Knowledge in the fight against microplastics from road traffic

The Government has commissioned VTI to develop and disseminate knowledge regarding the emission of microplastics from road traffic.


How to make autonomous vehicles coexist with other traffic

The road infrastructure must be prepared for self-driving vehicles – especially in the beginning when the concepts are still new. Researchers are contributing to this through CoEXist, an EU-funded research project in which VTI participates as the largest...


Electric roads: ‘Standardisation is an important factor for a future European transport system’

VTI employees recently arranged a workshop in Brussels on the standardisation of Electric Road Systems (ERS). ERS has become increasingly relevant as a possible method for reducing the transport sector's environmental impacts, especially in terms of climate...
