There is an urgent need with any new vehicle safety system to obtain feedback on the real-world performance, which may be quite different from earlier laboratory trials. However it typically takes several years for a new system to penetrate the vehicle fleet in sufficient numbers to support rigorous effectiveness measures. This methodology brings together accident data from seven countries in a common format and applies a new, coordinated induced exposure method to provide a single effectiveness estimate. The system was used to evaluate the effectiveness of ESC with the final result that in the UK the use of ESC resulted in a 27% reduction in crashes on rural roads and motorways in dry weather and a 40% reduction in wet weather.
The report has been used as the basis to integrate requirements for Electronic Stability Control systems within the EuroNCAP test protocols.
