The road safety benefits of intelligent speed assist (ISA) have been demonstrated in a number of projects worldwide. These benefits, however, are yet to be replicated in the heavy vehicle industry. With freight travel by road predicted to double by 2020, fuel costs predicted to rise and environmental issues looming large, the role of speed management in helping companies to reduce crashes, contain costs and remain competitive is likely to play an increasingly important role in the operational plans of many transport operators. In this regard, ISA may have an important role to play. A small-scale trial conducted by the Transport Accident Commission (TAC) in collaboration with the Victorian Transport Association (VTA) and with the cooperation of several heavy vehicle companies sought to assess the relative merits of ISA in terms of speed choice, fuel consumption, and driver acceptability. This paper discusses some preliminary results from Phase One of the data analysis.
