This study investigates whether Turkey utilizes its road transportation indicators efficiently or not within the framework of the European Union (EU) accession process. In addition, it aims to demonstrate Turkey’s current position compared to other EU countries by performing relative efficiency analysis on road transportation indicators. Data Envelopment Analysis, which is among efficiency measuring methods and used in this research, is a non-parametric method that is based on linear programming principles. In the analysis, three different models were formed in order to determine the dimensions of different road transportation parameters with the aim of minimizing the number of accidents and the number of casualties in accidents. As a candidate for the EU membership, Turkey’s road transportation performance was demonstrated in this study using Data Envelopment Analysis in comparison to members (27 countries whose data were fully accessed) of the EU, which requires its members of fulfilling certain criteria and targets.
