This paper evaluates the benefits of equipping European light goods vehicles (LGV) with active speed limiters and compares these benefits with those of other safety measures. In evaluating the impact of speed limiters we use a microscopic traffic simulation model which captures not only the impact of speed limiters on equipped vehicles but also the interaction between equipped and non-equipped vehicles and the resulting impact on non-equipped vehicles. The simulation results indicate that speed limiters can reduce traffic speeds by as much as 10%. Consequently, a significant reduction in the accident rate might be achieved. The safety effects and associated costs of active speed limiters are evaluated and compared to five other safety measures using a cost benefit analysis (CBA).These measures include the installation of electronic stability protection (ESP), digital tachographs, event data recorders (EDR), seat-belt reminders and seat-belt lock systems and the implementation of a professional driver training program. The CBA analysis yielded B/C ratios greater than 1 for a speed limiter set at 100 km/h, for a professional driver training programme and for devices to increase seatbelt wearing, indicating that these safety systems are economically justified for LGVs.
