Effektiva kontraktsmodeller för vägunderhåll


The study in this report reviews international experiences of contracting of routine road maintenance. The study describes the contracting models used in Norway, Scotland and Ontario (Canada), as well as the results from the relevant research literature. Focus has been to map differences in efficiency between traditional and performance-based contracting, as well as the effects of incentives, risk sharing, competition and quality dimensions in contracting. The results show that Ontario and Norway have largely performance-based contracting models. Recently, some aspects of these contracts have been reconsidered because of problems mainly with respect to winter maintenance. In Ontario, quality is now considered as one component for identifying the winning bidder; Norway has a new reimbursement model that aim to balance the contractors’ incentives. Also, Norway is testing new contracting models in five areas. Scotland uses traditional contracts and is testing a new performance indicator to improve winter maintenance by using measurements of friction. In the literature, the view on performance-based contracting is often positive. But no study has been found that measures the efficiency of different contracting models that accounts for possible simultaneous changes in quality or long-term effects.

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...

Crash testing bicycles at VTI

For the first time single bicycle crashes have been simulated at the VTI crash safety laboratory.


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)...
