Research into the auralisation of road traffic noise has drawn more attention in the recent years, as it can provide a more direct and immersive experience with which to communicate the implication of major urban design decisions with city planners and the public. Some synthesis models of single vehicle pass-by noise, and methods for outdoor sound propagation modelling have been proposed, which may be integrated for auralisation of traffic flow scenes. In this paper, a framework for traffic flow auralisation is presented. The synthesis model is composed of multiple single vehicle pass-by examples, based on tyre noise and propulsion sound synthesis. A first-order image source method is implemented, as a first approximation to represent sound propagation across a local region of a wider urban environment. The resulting plausibility of the proposed traffic flow auralisation model under different traffic flow scenes are under assessment using subjective listening tests.
