Cykelflödesvariationer i Stockholm och Göteborg: delrapport inom SAMKOST 3


The purpose of this project is to clarify the possibilities and the need for a pilot study aimed at measuring the marginal cost of congestion on bicycle paths. The goal of the measurements are exclusively to quantify the value of the delay caused by one further cyclist being present on the bicycle path. Ultimately, the goal is to be able to evaluate measures to broaden or otherwise improve the bicycle infrastructure.

This memorandum describes variations in cycle flow over a longer period of time, over one year and over a day (during months and days with high flows) in Stockholm and Gothenburg, with the aim to estimate when measurements should be made of the extent and intensity of significant congestion on bicycle paths.

Cycle flows vary by approximately a factor of 4 in Stockholm during the year in places with large flows and slightly less in Gothenburg, about a factor of 3. During peak hours, cycling flows show large variation during a day with shorter periods of high flows in the morning and afternoon.

The presence of costly congestion can therefore be expected to be quite short in Sweden's two largest cities. An example indicates that at 20 percent of all bicycle passages across the Liljeholmen bridge in Stockholm, the cyclist experiences high levels of presence of other cyclists. However, this example is not claimed to be representative either this or other locations in the inner city of Stockholm.

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...


Research on passenger and freight transport research

Shift2Rail is a European railway project that works actively to create innovations within the railway sector. IMPACT-2 is a project within Shift2Rail that follows and evaluates the innovation projects. How are the innovations coming along? Are they beneficial...


How vehicles can avoid accidents on newly paved roads

Friction is an important property for road safety. VTI has investigated how roads change in the first few weeks after surfacing work has been completed. Researchers recommend posting warning signs when the road is opened and waiting at least three weeks to...


VTI contributes to study on older drivers and accidents

On behalf of and in collaboration with the Swedish Transport Agency, VTI has carried out a study of older drivers and the link between illness and traffic accidents. The Transport Agency has now published the results.
