The paper examines factors affecting fatality risk of pedestrians, cyclists, motorcyclists, and moped riders in seven EU countries using data from CARE database. Method: Comparing acci- dent severity indicators between countries is problematic because of data quality issues, different degree of underreporting, and different exposure levels. To avoid bias arising from these issues, fatality risk is modeled with binary logistic regression. Risk factors considered include accident location by area type, junction type, and trafc control, as well as lighting condition. Results are presented as odds ratios of fatal accident outcome in different countries under specic circumstances compared to reference conditions. It is shown that the error in OR values due to underreporting is small. Results and discussion: Wide condence intervals of the odds ratios in some countries conrm problems with accident data quality. Fatality risk is always higher for non-urban ver- sus urban area and for darkness versus daylight conditions, but the odds ratios are different for different coun- tries. Inconsistent results are obtained for accident location with respect to junction and its control type. Possible reasons for these differences are suggested and discussed. Practical applications: The proposed method avoids the data quality bias of accident severity indicators, thus, it can be used in international comparisons of vulnerable road user accidents. The article ndings also support the concept of changes in legislation, such as re- ducing the speed limit in urban areas in Poland at night. Generally, the experience of countries with low VRU fa- tality risk identied in the article can be transferred to those with a higher risk. © 2018 National Safety Council and Elsevier Ltd.

Introduction Based on the trafc accident statistics, in the whole European Union (EU) vulnerable road users (VRU) constitute 46% of all trafc fatalities and 53% of all seriously injured accident victims. Vulnerable road users include pedestrians, cyclists, motorcyclists, and moped riders. Gravity of the VRU safety situation has been recognized by international bodies such as the World Health Organization (WHO) and the European Union and is reected in their trafc safety programs and campaigns (European Commission, 2010; World Health Organization, 2010). The study reported here is focused on seven EU countries taking part in research project InDeV: In-Depth understanding of accident causa- tion for Vulnerable road userswhich is carried out under the Horizon 2020 Programme (Project InDeV website, 2018). These countries are: Belgium, Denmark, Germany, the Netherlands, Poland, Spain, and Swe- den. The seriousness of the problem is evidenced by the fact that in those seven countries during ve-year period (20092013) there were over 1.24 million VRU victims of road accidents (CARE database website, 2018). While the general trafc safety situation has been im- proving in recent years, in some countries we see an increase in the VRU share of all accidents and even in the absolute numbers of these accidents. The objective of the study task reported here was to identify road in- frastructure-related conditions and factors that have a negative impact on VRU trafc safety. Analyses of accidents suffered by pedestrians, cy- clists, as well as riders and passengers of mopeds and motorcycles were carried out in order to determine the largest problems with their safety and to identify locations and situations where these types of accidents are most likely to occur. It is hoped that lessons learned in low acci- dent-risk countries can be transferred to countries where this risk for vulnerable road users is still high. The paper is organized as follows: part 2 shows the background on prior research into vulnerable road user safety and part 3 presents sta- tistics on safety situation of VRUs in Europe. Part 4 presents the method- ology adopted in this study, part 5 reports on the results of fatality risk Journal of Safety Research 68 (2019) 4957 Corresponding author.
