The safety benefits of electronic stability control (ESC) have been demonstrated in a relatively large number of studies conducted over a short time-span. These benefit studies have however focussed on the effectiveness of ESC in passenger cars and more recently 4WD vehicles. There is limited research as to the effectiveness of ESC in the light commercial vehicle range. This project aimed to determine the benefits, if any, of ESC fitment into light commercial vehicles for Australia for the period 2010 to 2039. The estimation of the effectiveness of ESC for light commercial vehicles was undertaken on the basis of two parameters: 1. ABS population projections used to estimate future vehicle sales, known as Projection Series A, B and C, and 2. ESC crash-injury reduction effectiveness. This determination entailed the estimation of the future number of light commercial vehicles sold, the future number of registered vehicles and the future number of crashes involving these vehicles. Using high future population growth (Series A) under a business-as-usual scenario – where it was assumed ESC would be fitted to all commercial vehicles by 2020 and hence nearly all registered vehicles in 2039 would have ESC fitted, the number of fatalities saved was 700 (range: 350 to 984) across the entire period, while it was estimated there would be 6934 fewer drivers seriously injured (range: 3467 to 9750). Large estimated savings with respect to minor injury crashes and property damage only crashes were also found. In financial terms, the savings to the community was estimated to be $A3.1 billion (range: $A1.575 billion to $A4.429 billion), depending on the ESC effectiveness value used. Additional benefits can be made by a more rapid installation of ESC into the light commercial fleet while the converse is also the case. BCR values using a $A450 fitment cost were positive across the effectiveness range, with little difference between future population projection series. These estimates were made with the best available evidence at the time of calculation however a range of assumptions were made. The information presented here provides only one of a number of inputs required for the determination of the mandatory fitment of ESC into Class NA vehicles in Australia.
