Pengembangan Model Perilaku dan Kepribadian Mengemudi pada Faktor Manusia (Studi Kasus Penyebab Kecelakaan di Jalan Tol)

Abstract

Belmera (Belawan-Medan-Tanjung Morawa) Toll is one of the toll roads in North Sumatra. Accidents at Belmera toll are still common. The accidents taking place on the toll road during the period from 2018 to 2022 consisted of single accidents with details of 20 cases (63.16%) of single-car accidents, 48 cases (25.26%) of fixed object collision, and 1 case (0.53%) of obstacle collision; as well as 20 cases (10.52%) of multiple car accident and 1 case (0.53%) of T-bone car collision. Along with many researches done, variables that cause such accidents continue to be discovered. Driving behavioral and personality model is the model that is being developed. In this study, driving behavioral and personality model is developed using associative research method. The obtained model shows that driving personality is indicated to have a significant correlation with accidents, in which technical skill is found to have the most significant correlation with accident with correlational value r=0.546, followed by driving violation, fatigued driving and abnormal behavior. Alcohol consumption is indicated to have the lowest correlation value, i.e. r = 0.127, meaning that it has a very weak positive correlation, yet it is proven to correlated with the cause of accidents; implying that alcohol consumption hardly has an effect on accident, but it is necessary and important to be acknowledged. Driving personality is also significantly correlated with accident, with the highest r value indicated by anxiety i.e. r value= 0.594, followed by driving knowledge, personality traits, aggressiveness level, mobile phone use, independent attitude and driving style, which overall result of the assessment falls into moderate category. The research findings develop a model that shows the correlation among driving behavior and personality with accidents, in which all investigated indicators have significant effects on accidents; the higher the correlation value is, the more significant the effects of the accident causes of driving behavior and personality on accident is. The correlation among these indicators is a novelty found from the research.
