An outline of parallel road traffic simulation based on the High Level Architecture (HLA) is presented. The methodology used to achieve parallelisation includes domain decomposition where the road network model is partitioned into sub-models and these sub-models are simulated on different cluster nodes. The domain decomposition concept is used for the parallelisation strategy where the road network is partitioned into parts and these parts are simulated on different computers. All federates simulating the different parts of the network communicate through the Runtime Infrastructure (RTI). The RTI services are used to realise simulation time advance and event synchronisation, and to the transfer of data across the network partitions. This paper discusses the implementation issues and also reports elements of the performance analysis.
