Fuel price impact on driver harsh behaviour improvement in Greece, July 2023

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

Impact of road safety culture elements on road crash risk in Greece, July 2023

An NTUA Diploma Thesis titled “Impact of road safety culture elements on road crash risk in Greece” was recently presented by Nikolaos Veneris. In order to achieve this, data from the “Safe Culture” research regarding private car and motorcycle drivers in Athens and Rhodes were exploited. Subsequently, the answers from questions that serve the purposes of this thesis were picked and classified, in order to develop binary logistic regression models. Results indicate that drivers probably understand the importance of more intensive traffic enforcement as a means of traffic accident reduction, the development of a common road safety culture in the island of Rhodes in contrast to that of Athens and, last but not least, the importance of factors such as driving frequency, age and experience, on traffic accident probability.  pdf5 ppt5

Economic assessment of free public transport in Athens, July 2023

An NTUA Diploma Thesis titled “Economic assessment of free public transport in Athens” was recently presented by Chrysavgi (Chrysa) Vagdatli. For this purpose, a social-economic analysis, in the context of a Cost Benefit Analysis (CBA), was conducted to assess the socio-economic impact of the FPT, up to the year 2030. In the framework of the CBA, four Scenarios for reduction of public transport tickets were examined. Consequently, a multinomial logistic model was developed to investigate for each of the three Scenarios the level preferring Athenians the FPT over private car, using data from a stated preference questionnaire survey. This social-economic analysis demonstrated that the introduction of FPT in Athens can contribute to social welfare mainly due to the modal shift from private cars to public transport.  pdf5 ppt5

Investigation of traffic and safety behavior of pedestrians while talking on mobile phone, June 2022

A paper titled “Investigation of traffic and safety behavior of pedestrians while talking on mobile phone” authored by Dimitra Typa, Dimitris Nikolaou and George Yannis, has been published in Advances in Transportation Studies. This study aims to investigate how hand-held cell phone conversation affects the behavior of pedestrians at signalized intersections in terms of both safety and traffic. In order to compare the behavior of distracted and non-distracted pedestrians, an outdoor environment experiment was carried out in real road conditions. Various demographic and behavioral characteristics were recorded, including mobile phone use. Initially, multiple linear regression models were developed in order to identify how cell phone use affects pedestrians’ speed. The results of the developed statistical models showed that pedestrians’ main traffic and safety characteristics were negatively impacted by distraction from hand-held cell phone conversation, as mobile phone use not only reduces pedestrians’ speed but also increases the likelihood that they will be involved in a collision with an approaching vehicle. doi

Driving and Alzheimer’s Dementia or Mild Cognitive Impairment: A systematic review of the existing guidelines emphasizing on the neurologist’s role, November 2021

A paper titled “Driving and Alzheimer’s Dementia or Mild Cognitive Impairment: A systematic review of the existing guidelines emphasizing on the neurologist’s role“, authored by Petros Stamatelos, Alexandra Economou, Leonidas Stefanis, George Yannis and Sokratis Papageorgiou is published in Neurological Sciences. The review of this paper included eighteen G/Rs, referred to drivers with dementia and 9/18 referred to drivers with MCI. A common approach among G/Rs is the initial trichotomization of patients in safe to drive, unsafe to drive, and undetermined cases, which are referred to a second-line evaluator. The most commonly used tests are the MMSE, TMT, and CDT. Although extensive multi-disciplinary research has provided useful information for driving behavior of cognitively impaired individuals, we are still far from a widely accepted approach of driving ability evaluation in this increasing population. A comprehensive assessment from a multi-disciplinary team in which the neurologist plays a critical role seems to be required, although this has not yet been implemented in any G/Rs. doi

National focus on individual freedom versus paternalistic values is a fundamental theme, which defines the status of traffic safety in different countries. Linear and logistic regression model results indicate that Greek drivers value freedom to take risk in traffic higher than drivers from Norway and Israel. Greek drivers also expect higher levels of risk taking from other drivers in their country, they report higher levels of risky driving themselves, and are more often involved in accidents. Thus, it seems that values have an important role in Road Safety Culture (RSC), legitimizing and motivating risky driving, which are related to accidents. doi
