Research output: Book/ReportCommissioned ReportResearch


This report provides a review of currently available Intelligent Transport Systems (ITS) and their expected and observed safety enhancing effects. ITS are technologies applied to the transport domain that may enhance mobility, efficiency and safety, among other benefits. The potential for ITS to
improve road user safety has been widely explored, and this report presents a review of what is known about the effectiveness of safety-relevant ITS. Each system has been classified as in-vehicle, infrastructure-based or cooperative, and further categorised as active, passive, or combined active and
passive. The systems are described in terms of their functional and technical characteristics, their likely crash relevance, and available literature regarding safety enhancing effects or disbenefits has been reviewed. In total, 138 systems have been reviewed in this report. Overall, it can be seen that while there may be inconsistencies among the literature regarding the expected degree of effectiveness of these systems, there is considerable evidence to suggest that ITS have had, and will continue to have, substantial positive effects on road user safety
