The capacity of transport infrastructure is one of the very important tasks in transport engineering, which depends mostly on the geometric characteristics of road and headway analysis. In this paper, we have considered 14 road sections and determined their efficiency based on headway analysis. We have developed a novel interval fuzzy-rough-number decision-making model consisting of DEA (data envelopment analysis), IFRN SWARA (interval-valued fuzzy-rough-number stepwise weight-assessment-ratio analysis), and IFRNWASPAS (interval-valued fuzzy-rough-number weighted-aggregate sum–product assessment) methods. The main contribution of this study is a new extension of WASPAS method with interval fuzzy rough numbers. Firstly, the DEA model was applied to determine the efficiency of 14 road sections according to seven input–output parameters.
Seven out of the fourteen alternatives showed full efficiency and were implemented further in the
model. After that, the IFRN SWARA method was used for the calculation of the final weights, while IFRNWASPAS was applied for ranking seven of the road sections. The results show that two sections
are very similar and have almost equal efficiency, while the other results are very stable. According to
the results obtained, the best-ranked is a measuring segment of the Ivanjska–Šargovac section, with a road gradient = 5.5%, which has low deviating values of headways according to the measurement classes from PC-PC to AT-PC, which shows balanced and continuous traffic flow. Finally, verification tests such as changing the criteria weights, comparative analysis, changing the parameter, and reverse rank analysis have been performed.
