This paper describes research at the Transport Systems Centre in collaboration with Quadstone, the developers of Paramics, to devise a rural two-way two-lane road simulation module and incorporate it in Paramics. This module allows for high speed traffic operation with limited overtaking in the face of restricted sight distance or oncoming traffic. It also considers vehicle performance on gradients, including a range of vehicle types. The research uses the outcomes of previous studies as the basis of the new model, along with collection of new data from rural roads in South Australia. The paper describes applications of the new model to freight vehicle performance on rural roads and of the effects of large vehicle (b-doubles) in rural traffic streams and their interactions with other vehicles. Further developments of the overall model to consider multi-modal transport systems, for example the balance between road and rail-based freight transport, are outlined.
