The effect of road safety advertisements on speeding behavior over time: A simulator study

Özkan, Özgün
Countermeasures to prevent death and injury in traffic are important for traffic safety. Human error is a critical component associated with road traffic accidents. Therefore, various organizations and decision-makers are trying to prevent risky behaviors via different methods. One of the most used methods of raising awareness and creating behavioral change is traffic safety campaign videos. The focus of the present study is speeding, which is one of the most dangerous violations on the road. The study aimed to investigate the effect of anti-speeding advertisements with different contents (fear, sad emotion, and factual information) on young drivers' speeding behavior. A total of 124 drivers (84 males, 40 females) aged between 18 to 26 (M = 22.81, SD = 1.80) participated in the study. Participants completed a questionnaire package including a demographic form, Driver Behavior Questionnaire, and drove the simulator scenario. The measurements were taken three times as baseline level and two follow-up levels to observe short and long time effects of the videos. According to the results, a general pattern was observed that the average speed of the drivers decreased immediately post-exposure, and it was measured as the highest after two weeks. On the contrary, drivers reported more frequent speed violations right after the manipulation than their baseline measurements. Significant time-dependent differences were observed in the emotional groups. Results were discussed in the context of related literature. Since social media campaigns may affect behaviors and attitudes, the results can help make more effective awareness videos about traffic safety.


The effect of implementation intention on speeding and acceleration overtime: A simulator study
Tekeş, Burcu; Özkan, Türker (2021-11-01)
Speeding is considered a major risk factor for road safety. In this study, implementation intention, which is a type of cognitive intervention, was designed to reduce speeding. Implementation intentions are self-regulatory ‘if-then’ plans, which are the subordinate concepts of goal intentions. Additionally, the type of goal was considered as a factor that could contribute to the subsequent behavior. An approach-type goal aims to achieve a behavior, whereas avoidance-type goals aim to avoid a negative, undes...
On Vehicle Aggressive Driving Behavior Detection Using Visual Information
Kumtepe, Omurcan; Akar, Gözde; Yuncu, Enes (2015-05-19)
Most of the traffic accidents are caused by human related factors. One of the most important human related factor in terms of traffic accident risk is aggressive driving behavior. Although driver aggressiveness is related with psychological reasons, it can be detected by observation of driving behavior using different sensing devices. This work presents a driver aggressiveness detection method exploiting the visual data obtained by on vehicle camera. The proposed method uses this visual data in order to ext...
The Relationship between Dispositional Affect and Traffic Locus of Control in Driving
Arslan, Burcu (2021-10-01)
The locus of control and dispositional affect of drivers has been claimed to influence driver behaviors. The positive affect and internal locus of control were usually claimed to be related to safety behaviors, whereas negative affect and external locus of control were shown as related to risky behaviors. To investigate the locus of control in the traffic context, multidimensional traffic locus of control (T-LOC) was developed with four dimensions; self, other drivers, vehicle/environment, and fate. In the ...
A Multimodal Approach for Aggressive Driving Detection
Kumtepe, Omurcan; Yuncu, Enes; Akar, Gözde (2016-05-19)
Aggressive driving behavior is among the important causes of traffic accidents. Hence, detection of driver aggressiveness has an importance in terms of decreasing the number of traffic accidents. Collected driving data while the vehicle is in traffic can be used to make inferences about the aggressiveness of the driver. In this study, a multimodal method is proposed in order to detect driver aggressiveness. The proposed method is based on utilizing the visual data taken from the on vehicle camera and sensor...
The Effects of psychological inoculation on drivers’ speeding behavior
Simser, Berfin Serenat; Özkan, Türker; Department of Psychology (2019)
Speeding is a widespread problem which can cause life threatening outcomes in traffic settings. The present study was aimed at measuring whether psychological inoculation (PI) based on an integrated model of Theory of Planned Behavior (TPB) and Prototype Willingness Model (PWM) can be used to reduce speeding behaviors of drivers. 95 male drivers aging between 19 and 30 took part in the study. As part of the PI intervention, all participants were given challenging sentences as exaggerated forms of their atti...
