The Administrative Data Research Network is an ESRC-funded project that ran from October 2013 - July 2018. It is currently at the end of its funding cycle and is no longer taking applications. Administrative data research will be taken forward in a new project, to be launched later in 2018.

Examining contributory factors in road traffic collision data involving older people in Wales

Research overview

Older people, especially those aged over 75, are more likely people aged 25-65 to be involved in road traffic collisions as either drivers or pedestrians. This project will examine contributing factors and compare people aged under and over 65 to identify salient factors for the older group. It will also use health data to examine whether older people involved in collisions are suffering from chronic or acute illnesses before the incident.



The findings will highlight any specific issues older people might have with driving, and how car design or training could help. Knowledge of collision locations could also be useful for planners and road safety officers. The researchers will discuss their findings with stakeholders to examine how best to intervene with older drivers with driver training programmes, licensing restrictions and driver cessation courses. The work might also help to predict which illnesses are associated with driving difficulties, helping health professionals to give advice about driving behaviour, refer their patient to a driver assessment centre or encourage them to give up driving.

More about the project

This research project will examine instances of road traffic collisions in people aged over 65 in Wales.

Contributing factors such as location, time of day, weather and junction type will be analysed which will allow comparisons to be made between accidents involving those aged under 65 and those aged over 65. This will enable the identification of any recurrent factors that contribute to collisions in older people and highlight areas where changes to infrastructure may be required or where automation of vehicles or re-training may help.   

The findings are useful in highlighting any specific issues older people might have with regards to driving, whether they are dangerous and how they might be mitigated through design of cars or training. Looking at collision locations could also prove useful for local planners and road safety officers to re-design roads that may be of specific issue for older people to traverse safely.
