This report reviews current developments in infrastructure-based safety-related ITS, documents their status in Australia and New Zealand, and makes recommendations for future developments in this area. A literature review is presented in which intersection warning systems, collision detection systems, lane departure warning, vehicle-activated speed warning, point-to-point speed enforcement, fixed speed cameras, intelligent speed adaptation (ISA), weather and flooding alerts, and automatic crash notification are examined, along with systems to protect vulnerable road users and developments in variable message signs. Workshop discussions were held across Australia and New Zealand. Discussion points are summarised in a table, with full summaries reported in an appendix. It was evident that there was relatively little contact between groups in the different authorities. There was also concern that up to the present, systems had developed in isolation with little reference to emerging standards in ITS, and an urgent need to get ready for the widespread availability of ITS in new vehicles was evident. Current developments impacting on the future of infrastructure based safety related ITS are discussed, including the allocation of dedicated radio spectrum in the 5.9 GHz range, developments in the intelligent speed assist area, and the launch of the dedicated short range communication cluster, established with the goal of facilitating the next wave of ITS developments. Recommendations for the organisation of future work in this area are made, including a research and development strategy. (Author/publisher)
