Highway transportation is the most used type of transportation and logistics way of the 20th century. Today, the increasing need for transportation and logistics has caused a great interest in the number of vehicles in traffic. In this direction, automotive manufacturers continue their efforts to develop new designs and production methods in order to make vehicles safer, reduce the damage they cause to the environment, and increase their comfort. This article examines crash boxes within the scope of vehicle security systems. Multi-cell crash boxes, which are innovative crash box designs, are investigated for the effects of the cross-sectional area on energy dissipation performance. Within the scope of the study, four groups of crash boxes with circular, square, hexagonal, and octagonal outer sections with different inner and outer wall variations were designed. Then, the crash performances of the designed crash boxes were determined. As a result of the studies, the developed O6 model is the best crash performance as developed 23 model. The specific energy absorption(SEA) and energy absorpstion (EA)of the O6 model are 20.37 kJ/kg and 9.98 kj respectively. The results of the O6 are the best value compared with the other 23 designs developed in this research.
