This paper focuses on the development and implementation of innovative technical solutions for improving the side protection of light commercial vehicles (category N1) in the context of road traffic. Commercial vans are taller and heavier than passenger cars. Also, they usually have the stiff structure at a higher height. Typically, vans have fewer occupants but carry a larger load. In the event of a crash, the geometric misalignment, rigid structure, and greater mass will affect the occupants of the smaller vehicle, resulting in a greater likelihood of serious injury or death to the occupants of the car. The safety of light commercial vehicle occupants has only partially benefited from the advances in vehicle safety over the past decade. Because of differences in mass, side collisions involving light commercial vehicles tend to have more severe implications for opponent vehicles. The results obtained will increase the safety of N1 vehicles in case of collisions involving occupants in real road traffic conditions.
