Abstract
The School Bus Routing Problem (SBRP) is a classic optimization problem with a massive potential for real applications that have a high impact on society. Research interest in this problem is constantly rising. Previous review papers with a time-space between them of 10 years have helped understand the different features studied by the research community about this problem. In this systematic review, we consider two new categories not discussed before: the incorporation of a mixed load composed of multiple schools, along with the inclusion of a smart element related to the availability of user information and communication in real-time to join the smart mobility trend. In addition, we discuss the lack of real applications in the SBRP in university contexts with a focus on the multi-load problems.
