Produktivitetsstudie: kvalitetssäkring av Trafikverkets egna kostnadsdata gällande drift och underhåll av vägar


Trafikverket (The Swedish Transport Administration) has been criticized for not systematically following up their productivity. This report is an initial study of the possibility to report productivity regarding maintenance on an aggregate level. The study builds on the Swedish Road Administration´s own databases VERA, Agresso, and the project leaders' own data. Three contracts have been studied in detail to assure that the cost data is consistent between VERA/Agresso and the project leader´s own data. The picture that emerges is that the cost data from VERA is of good quality for the three projects. This means that data from the project leader is consistent with data from VERA. Minor deviations between the data sources are due to a vague definition of maintenance in the VERA coding. This needs to be clarified before going further with the VERA data. VERA is now discontinued in favor of Agresso, which means that VERA can only be used for describing productivity up to 2009. The quality assurance of cost data from Agresso has not been able to be done in the same extent. Studies of productivity need to be controlled concerning the quality of the service delivered. A maintenance contract with a lower cost per kilometer is not necessarily better than a contract with a higher cost if the latter has a much higher quality of the service provided. A first step in controlling this is to separately disclose both winter maintenance and additional orders.
