Multi-combination vehicles (MCV) are road freight vehicles with a prime mover towing two or more trailers. The research aims to compare the behaviour of vehicles surrounding MCVs and other general access vehicles. Identification of these characteristics will aid road authorities in safely authorising access to MCVs. Video footage was collected on a four lane divided urban motorway section that provides access to the Port of Brisbane, Australia. This paper shows that passenger car drivers shy away from the centreline more when travelling adjacent to semi-trailers and B-doubles compared to travelling adjacent to other passenger cars. However, on average the passenger car drivers felt comfortable enough to position their vehicle within the marked lane. Between 4-6 per cent of drivers positioned their vehicles outside the lanes when travelling adjacent to either of these heavy vehicles. There is no statistical difference between lateral behaviour around semi-trailers and B-doubles. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E211825.
