Millions of people travel on our roads daily and transportation is key to the development of modern society. The US and the European Union promote safe, efficient and environmentally friendly transport systems, which is closely related to speed as it affects fuel consumption, travel time and accident risks. We focus on understanding drivers’ risky decisions and behavior, such as speeding, driving too close to the vehicle in front, texting and other distracting activities. An increased knowledge of why drivers engage in such behaviours is important in order to take measures against them and enables the design of effective interventions of risk communication. Another focus of research is driver decision making in cars with increasing use of information technology and automation that may improve safety considerably from a systems perspective. From a human factors perspective these technical advances also create situations demanding quick driver decisions and interventions.
