The paper summarizes the results of the programme "Traffic safety effects of High Capacity Transport (HCT) vehicles and suggestions for compensatory measures" this far. An analysis of ten years of Swedish accident data shows that "long" combinations (18.76m to 25.25m) had lower rate of fatal or severe accidents per billion vehicle kilometres travelled compared to medium and short vehicles. It is argued in the literature that HCT vehicles would, on average, reduce the number of Heavy Goods Vehicles (HGV) accidents because fewer vehicles would be needed to transport a given amount of goods. However, further investigation is required of the causal relationship between crash risk and a HGVs’ weight, length, number of units, links and axles in certain traffic situations. One way to ensure the safety performance of HCT vehicles, and HGVs, is to assess them by Performance Based Standards. The paper describes the plans to adapt PBS to Swedish conditions, and to monitor Swedish HCT vehicles under trial with the surveillance system Intelligent Access Programme (IAP).
