Traffic Safety Cultures and the Safe Systems Approach – Towards a Cultural Change Research and Innovation Agenda for Road Safety (TraSaCu)

Traffic Safety Culture (TraSaCu) aims at developing a cultural approach in road traffic safety research and accident prevention. Traditional approaches to traffic safety shall be complemented by a cultural perspective which has emerged recently in safety research and prevention. Safety culture has been identified as an important factor of road safety as it helps understanding and explaining the typical patterns of risk perception and risk taking that prevail in different national, regional or local traffic systems as well as their relationships with numbers and forms of accidents. A weak safety culture produce higher numbers of accidents which are more severe. A strong safety culture helps reducing the number of accidents as well as mitigating their severity. It strengthens safety relevant attitudes and behaviour and it is also a condition for making road safety measures more effective. According to a working definition of the US Department of Transportation Safety Council (US DOT), traffic safety culture is defined as the shared values, actions, and behaviours that demonstrate a commitment to safety over competing goals and demands. However, a unified concept of safety culture still does not exist. Therefore, the project will elaborate an empirically grounded and theoretically adequate concept of traffic safety culture, based on this definition by conducting a number of case studies of different traffic safety cultures across Europe. It focuses on the safety cultures that emerge under different institutional, demographic and topographical conditions and their influence on the numbers and forms of accidents. Research focuses on the culturally mediated interaction between traffic participants and their environment in terms of the cultural patterns of risk taking and risk perception. It also looks at those cultural elements that can be changed easily in order to improve road safety of the investigated traffic systems.


Traffic safety climate attitudes of road users in Germany
GEHLERT, Tina; HAGEMEİSTER, Carmen; Özkan, Türker (2014-09-01)
This paper validates traffic safety climate attitudes based on a representative sample of road users of all travel modes. We use the German version of the Traffic Climate Scale (TCS) which was applied in a large-scale road safety survey in 2010. A total of 1680 people were surveyed. The sample is representative for socio-demographic characteristics and travel mode choice in Germany. Factor analysis reveals a three-factor structure of traffic safety climate with the factor 'External affective demands' descri...
Traffic climate and driver behaviors: The moderating role of driving skills in Turkey and China
Üzümcüoğlu, Yeşim; Özkan, Türker; Wu, Chaozhong; Zhang, Hui (Elsevier BV, 2020-01-01)
© 2020 National Safety Council and Elsevier LtdIntroduction: While road traffic accidents and fatalities are a worldwide problem, the rates of road traffic accidents and fatalities show differences among countries. Similarly, driver behaviors, traffic climate, and their relationships also show differences among countries. The aim of the current study is to investigate the moderating effect of driving skills on the relationship between traffic climate and driver behaviors by country. (Turkey and China). Meth...
Road safety evaluation of urban major arterials case study of 1071 Malazgirt Noulevard in Ankara
Demirel, Mehmet; Tüydeş Yaman, Hediye; Department of Civil Engineering (2019)
Traffic accidents cause damages in social, economic and health of communities, which have severe and serious costs in the long run. Infrastructural elements are also crucial, which can be avoided beginning from planning stages. Road Safety Audit (RSA) is a concept that lists and checks various design and operational characteristics of road projects and segments, to either prevent accidents and/or reduce their severity, implemented in many countries. However, lack of RSA legislation in Turkey is a major prob...
Speed-Related Traffic Accident Analysis Using Gis-Based Dbscan And Nnh Clustering
Topcuoglu, B.; MEMİŞOĞLU BAYKAL, TUĞBA; Tüydeş Yaman, Hediye (2022-8-05)
To ensure road safety and reduce traffic accidents, it is essential to determine geographical locations where traffic accidents occur the most. Spatial clustering methods of hot spots are used very effectively to detect such risky areas and take precautions to minimize or even avoid fatal or injury accidents. This study aims to determine speed-related hot spots in the pilot Mersin Region, which includes seven cities in the central-southern part of Turkey. Two different hot spot clustering methods, the Neare...
Traffic climate scale: Comparing samples from Turkey and Sweden
Wallén Warner, Henriette; Öztürk, İbrahim; Özkan, Türker (2021-01-01)
Traffic climate is a recent and one of the essential topics in traffic and transportation research. Various studies have examined the relations of traffic climate with driving outcomes such as accidents by using different versions of the Traffic Climate Scale (TCS). In a recent attempt, 16-items and 38-items versions of the TCS were examined in different countries. With respect to that, the present study aims to investigate the psychometric properties of 16-items and 38-items versions in samples from Turkey...
