Deciding on speed: "do knowledge of speed limits and other factors influence our way of driving?"

Gür Erdost, Begüm
The problem of Road Traffic Accidents is a growing epidemic all over the world; with an annual bill of 1.3 million lost lives (WHO, 2014). Human factors contribute more than 90% of errors causing these accidents; the main cause being speeding (Oppenheim and Shinar, 2011). Speeding was found to be the cause of 43% of all fatal and injury accidents in Turkey (TurkStat, 2013). Hence, understanding the underlying factors of speeding is of utmost importance for improving traffic safety. This study investigated whether awareness of speed limits on a certain road, along with other factors affected speed choice, analysing the data obtained from Road Safety 10 (RS10) project conducted in Turkey. RS10 project was funded by Bloomberg Philanthropies under the scope of Global Road Safety Program to reduce deaths and serious injuries on the roads of 10 low and middle income countries (LMICs), including Turkey, between 2010 and 2014. Data collected from Ankara and Afyonkarahisar, in three different waves was used for the analyses. Overall, 755 drivers from Afyonkarahisar, and 1581 drivers from Ankara were interviewed using a standardized speeding survey. Hierarchical regression analyses revealed significant effects of age, gender, education level and annual mileage on excessive speeding behaviour. Perception of speed fines as governmental income, setting a safe margin of speed above the speed limit; and perception of excessive speed as a cause of traffic accidents also significantly affected the drivers' choice of speed. However, no significant effect of knowing the speed limits on excessive speed was observed


Driver aggressiveness analysis using multisensory data fusion
Kumtepe, Ömürcan; Akar, Gözde; Department of Electrical and Electronics Engineering (2016)
Every year a vast number of traffic accidents occur globally. These traffic accidents cause fatalities, severe injuries and huge economical cost. Most of these traffic accidents occur due to aggressive driving behaviour. Therefore, detection of driver aggressiveness could help reducing the number of traffic accidents by warning related authorities to take necessary precautions. Although aggressiveness is a psychological phenomenon, driver aggressiveness can be analysed by monitoring certain driving behaviou...
Young driver behaviors in relations to the implicit and explicit driving skills
Öztürk, İbrahim; Özkan, Türker; Department of Psychology (2017)
Road traffic accidents are one of the important public health problems for all age groups, especially for the young people. Young drivers show more aberrant driver behaviors and are overly represented in road traffic accidents. The driving skills and driver behaviors are important predictors of road traffic accidents. Driving skills and driver behaviors might be measured by using self-reports, driving simulators, and implicit measurements. In this thesis, the relationship between self-reported and implicit ...
The Effects of mind wandering on simulated driving performance
Dündar, Ceyda; Mısırlısoy, Mine; Özkan, Türker; Department of Psychology (2015)
The significant amount of traffic crashes is caused by driver distraction. Studies showed that secondary tasks, which lead to driver distraction, are one of the important reasons for traffic crashes. Additionally, mental distraction, such as mind wandering, may be more dangerous than secondary task distractions. The current study mainly focuses on the effect of mind wandering on driving performance. A novel approach, pre-post probe approach, is developed to assess the mind-wandering episodes of drivers. Add...
Synthesis of formal control strategies for traffic systems
Bardakçı, Kemal Çağrı; Aydın Göl, Ebru; Department of Computer Engineering (2018)
The problems caused by traffic congestion affect human life adversely. Wasted amount of time, fuel and money as well as adverse effects to environment are examples of these problems which reduce life quality. Studies on traffic management underline importance of traffic network control mechanisms. Different configurations of roads and signalized intersections complicate interactions among vehicles and pedestrians. Hence, traffic control systems, which need to satisfy complex specifications, should be constr...
Development of the professional driver behavior questionnaire
Yılmaz, Şerife; Öz, Bahar; Özkan, Türker; Department of Psychology (2018)
The aim of the present study was to develop a comprehensive scale measuring professional drivers' driver behaviors. For this reason, a semi-structured interview form was prepared and applied to different professional driver groups in order to collect behavioral examples displayed in traffic context (Study 1). These examples were grouped based on Reason's taxonomy of human error and Professional Driver, Driver Behavior Scale (PDBQ) was developed. PDBQ along with some other behavior scales such as ODBQ and DB...
