Safety KPIs 2011/12
This measure reports all Category A SPADs (signals passed at danger), which are those instances where signals have been passed when a stop aspect, end of in-cab signalled movement authority, or indication (and any associated preceding cautionary indications), was displayed correctly, in sufficient time for the train to be stopped safely at the signal or end of in-cab movement authority. The table below shows the number of Category A SPADs for 2011/12 compared with previous years.
There were 278 category A SPADs in 2011/12, a seven per cent improvement on 2010/11 and although 0.7 per cent below the target, it is only four more than the lowest ever recorded number in 2009/10. We have analysed the trends behind signals passed at danger (SPADs). In doing so we have identified signals around the country where further work and investment will make our network safer. We are also working with train operators to understand those SPADs which arise from driver error.
