Rolling 3 year average for the number of people killed or seriously injured (KSI) on Shropshire roads.
The number of people Killed or Seriously Injured (KSI) on the roads in Shropshire is calculated by using a rolling 3-year average. At the end of 2008 there was an annual average of 162 people killed or seriously injured on the roads of Shropshire. Since 2012 the annual average over three years had stabilised to around 125. During 2013 the number of KSI was low. As these numbers are now being removed from the 3 year calculations the higher KSI figures for 2016 are resulting in an increased 3-year average. As at the end of June 2017 the rolling three-year average has now increased to 160.7 returning to the averages last seen in 2007/08.
It should be noted that this data reflects casualties, not accidents. The number of casualties can be influenced by the number of vehicle occupants which is unrelated to the highway network. There is likely to be a proportionally higher number of KSIs in Shropshire as a result of its road network. The current trend is that more KSI casualties are occurring on rural 60mph and national speed limit roads, of which there are many in Shropshire. Previous data suggests that particular spikes do occur on the network and are random in nature. West Mercia Police do not consider this increase to be specifically related to anything that is within the Highway Authority’s control. During 2016, the Transport and Highways team has refined its accident review process to look at accident cluster sites. This will enable Shropshire Council to prioritise its accident data led interventions annually.Shropshire Council regularly liaise with both the Safer Roads Partnership in Warwickshire and West Mercia, and West Mercia Police where local information is shared and acted upon where appropriate.
The rate of KSI per 100,000 population in Shropshire is higher than the national average. Rates of KSI by population are particularly affected by accidents involving motor cycles. Although motorcyclists and moped users make up only 2% of all road traffic, they are involved in around 30% of all collisions where somebody is killed or seriously injured. The Safer Roads Partnership works with local partners and motorcycling groups to try and reduce the number of motorcyclists killed and injured in collisions.
Five years of road accident data is currently being analysed to identify any potential causal effects.
