Wherever possible any education, training or publicity measures should be evaluated in order to see if the desired outcomes have been achieved. As accidents are relatively rare occurrences it is likely that a combination of attitude change assessment and incident avoidance measurement will provide best feedback. Satisfaction surveys are unlikely to give valid results.
Accident data analysis will provide long term information but it is difficult to isolate the effect of factors external to the delivered measures. Future evaluation in the UK may use the protocols developed by the Organisation for Economic Co-operation and Development (OECD) and used in the Motorcycle Accident In-Depth Study (MAIDS). MAIDS is a detailed review of almost a thousand motorcycle accidents across five countries in Europe (OECD 2001, ACEM 2004).
