The European Parliament has adopted regulation (EU) 2019/2144, which will make several ADAS (Advanced Driver Assistance System) mandatory in new models from June 2022 onward and in all new vehicles from June 2024 onwards. However, due to the slow renewal of the vehicle fleet, it will take several years before a meaningful portion of the fleet is equipped with these lifesaving systems. To compensate for this, the safety of existing vehicles could be improved with retrofit ADAS systems. The objective of this study is to assess the feasibility, costs and benefits of retrofitting ADAS. This study examined the technical feasibility of various retrofit ADAS systems and assessed the following in greater detail: Forward Collision Warning, Lane Departure Warning, Advanced Driver Distraction Warning, Speed Limit Information, Reversing Detection, Tyre Pressure Monitoring system, Turn Assistant for trucks and 112 eCall. The study examines the potential safety impacts of retrofitting the vehicle fleet and presents a cost-benefit assessment for the measures. This report addresses voluntarily installable measures as well as mandatory measures.
