Single-bicycle crashes in Finland - Characteristics and safety recommendations.

Problem: Increasing the role of cycling is necessary to reduce physical inactivity. While promoting cycling, attention should also be given to traffic safety. Hence, a better understanding on the underlying factors and safety recommendations of cyclist crashes is needed.

The role of vision-related problems in fatal road accidents in Finland.

Purpose: To evaluate the significance of vision-related problems in fatal motor vehicle accidents (FMVAs) based on a systematic investigation process by multidisciplinary road accident investigation teams (RAITs).

Methods: Retrospective registry-based study of all FMVAs during the years 2012-2016 in Finland in which driver causing the accident had a valid Finnish driving licence and the operated motor vehicle required having a driving licence.

Results: There were a total of 968 FMVAs.

A short survival time after last psychiatric hospitalization in drivers with psychotic disorder killed in fatal motor vehicle accidents.

Background: Research-based evidence on patients with psychotic disorders involved in fatal motor vehicle accidents (FMVA) remains limited. The current study analyzes the characteristics of FMVA drivers, who had been hospitalized due to psychotic disorders within a five-year-time-period prior to their death in traffic accidents.

Material And Methods: Data sources included three national registers: The Finnish Database of Road and Cross-Country Accidents, the Care Register for Health Care and the National Cause of Death Register.

Crash risk of ESC-fitted passenger cars.

We examined both fatal and injury at-fault crashes of a population of passenger cars fitted with electronic stability control (ESC). Crash rates were calculated in relation to both registration years and mileage. Crash rates were also calculated for a non-ESC car population and crash rate ratios were calculated to compare the crash risk between ESC-fitted and non-ESC-fitted passenger cars.

Light motor vehicle collisions with heavy vehicles - Psychosocial and health related risk factors of drivers being at-fault for collisions.

Background: Fatal head-on collisions between passenger cars and trucks are sometimes thought as self-inflicted death of the passenger car drivers.

Methods: A total of 378 Finnish drivers of light motor vehicles (LMV) died in collisions with heavy vehicles between the years 2002-2011. These male and female drivers, who were considered as being at fault, and whose collisions with heavy vehicles occurred in the oncoming vehicle's lane, were explored in relation to information on their socio-demographics, physical and mental health condition and driving-related factors.

Airbag deployment-related eye injuries.

Objective: We studied the correlation between airbag deployment and eye injuries using 2 different data sets.

Methods: The registry of the Finnish Road Accident (FRA) Investigation Teams was analyzed to study severe head- and eyewear-related injuries. All fatal passenger car or van accidents that occurred during the years 2009-2012 (4 years) were included (n = 734).
