The roads with the highest collision rates located in Galway, Wexford and Longford, with the most dangerous road segment along the west’s N59 – and Galway appears eight times in top 20 most dangerous road segments.

Gamma Location Intelligence, the location intelligence services provider, has released analysis on the most treacherous road segments* in Ireland.

The company, which provides location-based insights to insurance companies and local authorities, has mapped out Transport Infrastructure Ireland data that shows that the roads with the highest collision rates – determined by the number of road accidents (injury collisions) per 100 million vehicle kilometres – are clustered in Galway, Wexford and Longford. Collisions are limited to those that resulted in an injury on major roads from regional to motorway.

Most dangerous stretch of road


The most dangerous stretch of road is in Galway, located just east of Kylemore Lough, from Cliften to near Leenaune along the N59. The second is between Abbey Square Roundabout and Seamus Rafter Bridge in Enniscorthy, while the third is at the Killashee Street, Ballymahon Street and New Street junction in Longford town.

Galway was also the county that appeared most frequently in the top 20 list with eight of the most dangerous road segments located there. Clare appeared four times in the top 20.

Gamma’s Perilfinder platform has an in-built Road Accident Model which collates data from the Road Safety Authority, Transport Infrastructure Ireland and the Central Statistics Office to analyse and present accident data to show where most collisions happen.

The software also offers risk assessment insights for other perils such as flooding, fire and subsidence.

Director of location intelligence for Gamma, Richard Garry said: “Overall, according to the data provided by Transport Infrastructure Ireland, collision rates are decreasing across the country. However, there are specific stretches of roads where the frequency of collisions is still high.

“Not only does this analysis show drivers where they need to take extra care, it is also useful for insurance companies as it identifies the areas which are worst for road accidents and enables them to better assess risk.”
