Feedback on driving style was developed and tested for enhancing the traffic safety of young drivers. At the age of 18-20, the risk of a car driver being involved in a traffic accident is multiple compared to middle age. As a person grows older, driving style settles down and risks are better avoided.
We studied whether giving feedback afterwards has an effect on the development of driving style. The feedback was developed during the study. Feedback was built up based on the location and speed data received from GPS satellites and digital map data (Digiroad). Feedback on driving style was sent to the young driver and the owner of the car (often a parent) for joint consideration. In each feedback, different drivers of one car were studied and compared with the average for the entire test group. Young drivers involved in other contemporary studies were used as a reference group.
In total, 38 young drivers participated - most of them driving a car owned by their parents. Data collection started in June 2010 and lasted 18 months, until December 2011. Data was collected continuously but there were some breaks in feedback. Indications of the positive safety effects of feedback were found in regard to speeding and high speeds in relation to curve radius. However, the number of test drivers was relatively low and differences between individual drivers were too great to draw clear conclusions. According to the inquiries sent to the drivers, the most desired feedback was risk increase caused by speeding, the number of strong accelerations around curves, and map showing the locations of speeding and high curve speeds.
Also the idea of using a driving diary together with the feedback to support learning of driving was presented and tested briefly. Even an idea of a feedback norm was discussed - which would enable comparable and safety-enhancing feedback to be received from different service providers. A science-based list of indicators and feedback needs further study.

Applications and equipment
Weekly driving style feedback as internet reports.
Equipment carried by test users
GPS data loggers installed and provided by PPCT Finland.
Pre-simulation / Piloting of the FOT
A few months during feedback system finalisation.
Method for the baseline
No feedback for the reference group.
Techniques for measurement and data collection
Wireless data transfer from loggers to server computers.
GPS. Additionally questionnaires and weather data. Data has been enriched with speed limit data from Finnish Digiroad.
The data could be made available but lacks cleaning and detailed documentation. We recommend Trafisafe instead.
Recruitment goals and methods
Recruited young drivers via their parents.
Methods for the liaison with the drivers during the FOT execution
Weekly driving reports, support e-mail, contacts if no data was received.
Methods for data analysis, evaluation, synthesis and conclusions
See final report.
