There is a great interest in increasing the efficiency of the transport system in Sweden, which makes the High Capacity Transports (HCT) an attractive solution. To gain more knowledge about HCT vehicles and their effects on traffic safety, infrastructure and environment, the Swedish government is undertaking a large research program focused on HCT vehicles in Sweden. One of the projects in the HCT program was “Performance based standards for high capacity transport in Sweden”. This project started at the end of 2013 to investigate the applicability of a regulatory framework based on performance based standards in Sweden, taking into consideration the winter road conditions. This paper presents a summary of the main outcomes of the project, which ended in 2017.
