Trafikarbete i tätort och på landsbygd

Urban Björketun
Jan R Eriksson

Three models have been designed that utilise existing databases to produce data that simultaneously describe the vehicle mileage divided geographically and among vehicle types. The databases which have been used are RES (data from a national travel pattern study), UVAV (a database for national transport of goods), the NÄTRA database (trade and industry transports in the county of Stockholm), VDB (database for Swedish road traffic), The vehicle register (implicitly) and geographical data (urban borders and SAMS zones).

The result of the project is models that provide exhaust emission models and dispersion models with traffic data.

The designed models can be generalised to other geographical partitions than urban – rural area.

A case study exploring firefighters’ and municipal officials’ preparedness for electrical vehicles

A VTI-study presents a social perspective on new vehicle technology. It explores the self-reported preparedness of the fire departments (i.e., rescue services) in Sweden’s three largest cities regarding rescue operations involving electrical vehicles (EVs).


Pioneering research on and about bicycles at VTI

Under what circumstances might cyclists lose tyre grip? What actions could then be taken to prevent a crash? VTI is currently developing a theoretical model of the behaviour of bicycle tyres during braking and steering in different situations and on different...


Virtual pedestrians create efficient stations

If more people are to choose sustainable travel, then the public transport stations of the future must be designed so that pedestrians can get where they are going quickly, without congestion or queues. The Swedish Road and Transport Research Institute (VTI)...
