Intersection accidents are a major problem worldwide. The development of equipment like active safety systems that have the potential to mitigate this problem is a likely enabler of global business growth and international competitiveness for the project's industrial partners. This project has indirectly contributed to the enhanced international competitiveness of the industrial partners by defining and applying metrics that inform the design of active safety systems. In the process, all partners in the project have leaned how to conduct rigorous scientific analyses of intersection traffic and driver behavior in intersections. We now have a deeper understanding of the constraints and issues associated with driver behavior, intersection accidents, and the design of systems that may reduce fatalities or serious injuries at intersections.
