An NTUA Diploma Thesis titled “Fuel price impact on driver harsh behaviour improvement in Greece” was recently presented by Panagiota Konstantakopoulou. It analyses the impact of fuel price on driver behaviour and explores how price changes can influence driving style, abruptness and speed. The research includes statistical data of fuel prices and driver behaviour for the years between 2019 and 2022.   The increase in fuel prices has led to a reduction in sudden acceleration/deceleration. It was observed that during periods of increased fuel price, drivers improved their driving style and were more attentive to the task of driving, performing fewer abrupt events. pdf5 ppt5
