Abstract
Driver behavior has been considered as the most influential factor in reducing fatal road accidents and the resulting injuries. Thus, it is important to focus on the significance of driver behavior criteria to solve road safety issues for a sustainable traffic system. The recent study aims to enumerate the most significant driver behavior factors which have a critical impact on road safety. The well-proven Analytic Hierarchy Process (AHP) has been applied for 20 examined driver behavior factors in a three-level hierarchical structure. Linguistic judgment data have been collected from three nominated evaluator groups in order to detect the difference of responses on perceived road safety issues. The comparison scales had been averaged prior to computing the weights of driver behavior factors. The AHP ranking results have revealed that most of the drivers are most concerned about the “Errors”, followed by the “Lapses” for the first level. The highest influential sub-criteria for the second level is the “Aggressive violations” and for the third level, the “Drive with alcohol use”. Kendall’s rank correlation has also been applied to detect the agreement degree among the evaluator groups for each level in the hierarchical structure. The estimated results indicate that road management authorities should focus on high-rank significant driver behavior criteria to solve road safety issues for sustainable traffic safety.
Highlights
More than 1.25 million people die each year as a result of road traffic crashes [1]
The present study demonstrates an integrated model to highlight the most critical driver behavior factors related to road safety; the presented model is comprised of the Analytical Hierarchy Process (AHP) method along with Kendall’s coefficient of concordance correlation
The Analytic Hierarchy Process (AHP) has been used to reflect choices based on the evaluator groups, while Kendall’s degree of correlation has been applied to estimate the correlation among the examined groups based on perceived road safety issues
Summary
More than 1.25 million people die each year as a result of road traffic crashes [1]. European roads have been observed as the safest in the world with a 19% decrease in road fatalities over the last six years. While achieving the strategic target of halving the number of road deaths between 2010 and 2020, which is still an extreme challenge, it is worth trying to save every single life [2]. The Road Safety Action Program (2014–2016) was integrated into the Hungarian Transport Strategy which sets targets to reduce the number of road fatalities by 50% between 2010 and 2020 [3]. The situation analysis of the Road Safety Action Program observes that most of the accidents are caused by human factors, influencing them becomes the most important goal of road safety actions [3]. The NHTSA’s 2008 [5] report specified that human error is the critical reason for 93% of crashes
