A paper titled “Innovative motor insurance schemes: A review of current practices and emerging challenges” authored by Dimitris Tselentis, George Yannis, and Eleni Vlahogianni, is now published in Accident Analysis & Prevention. The objective of this paper is to provide a review of the most popular and often implemented methodologies related to Usage-based motor insurance (UBI). UBI schemes, such as Pay-as-you-drive (PAYD) and Pay-how-you-drive (PHYD), are a new innovative concept that has recently started to be commercialised around the world. The main idea is that instead of a fixed price, drivers have to pay a premium based on their travel and driving behaviour. There is evidence that UBI implementation would eliminate the cross-subsidies phenomenon, which implies less insurance costs for less risky and exposed drivers. It would also provide a strong motivation for drivers to improve their driving behaviour, differentiate their travel behaviour and reduce their degree of exposure by receiving feedback and monitoring their driving preferences and performance, which would result in crash risk reduction for each driver individually but also for the whole population.
