VTTI is a research organization focused on transportation safety that has over 400 employees and 12 research centers. It has extensive capabilities for testing connected vehicle systems through its smart road, research vehicles equipped with data acquisition systems, and naturalistic driving studies involving thousands of participants. Current projects include assessing vehicle-to-vehicle and vehicle-to-infrastructure technologies to improve safety applications like collision avoidance as well as traffic and environmental applications.
