Traffic and Transportation Psychology is substantially concerned with the what, the how, and the why of road safety. As well it is heavily involved in the field of evaluation of countermeasures, including work in simulators where research is often multi-disciplinary in nature involving engineers and statisticians. Specific areas in which Traffic Psychology is particularly visible include seat belts, behavioural measures relating to enforcement, the development of road signage, speed limits, driver distraction, and the older driver licensing question (when should people quit?).
Division 13 (Traffic and Transportation Psychology) of the IAAP and the ICTTP6 Organizing Committee are now inviting bids to host the Seventh International Conference on Traffic and Transport Psychology, in 2020.
