Τhe European Transport Safety Council (ETSC) has published the 42nd PIN Flash Report titled How Traffic Law Enforcement Can Contribute to Safer Roads with the active contribution of NTUA. Exceeding speed limits, drink- or distracted- driving, and failure to wear a seatbelt are among the important factors leading to death and serious injury on European roads. Road safety laws have been adopted to guide drivers in their behaviour. Many comply with them willingly. Others, however, would be less likely to comply if it were not for fear of being detected and sanctioned. This is where traffic law enforcement comes in. This Report gives an overview of the current state of road traffic enforcement across the EU, with recommendations for action.  link pdf5

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

The role of values in road safety culture: Examining the valuation of freedom to take risk, risk taking and accident involvement in three countries, January 2022

A paper titled “The role of values in road safety culture: Examining the valuation of freedom to take risk, risk taking and accident involvement in three countries” authored by Tor-Olav Nævestad, Tova Rosenbloom, Rune Elvikand  is published in Transportation Research Part F: Traffic Psychology and Behaviour. 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

Analysis of the impact of COVID-19 on collisions, fatalities and injuries using time series forecasting: The case of Greece, November 2021.

A paper titled “Analysis of the impact of COVID-19 on collisions, fatalities and injuries using time series forecasting: The case of Greece“, authored by Marios SekadakisEva MichelarakiChristos Katrakazas and  is  published in Accident Analysis & Prevention. Three different Seasonal Autoregressive Integrated Moving Average (SARIMA) time series models were implemented on road casualties data for the period 2010-2020 in order to compare the observed measurements to forecasted values intended to depict assumed conditions; namely, without the appearance of the COVID-19 pandemic. The results demonstrate that fatalities and slightly injured rates were significantly increased during the lockdown period and the subsequent months. Overall, it can be concluded that a worse performance was identified in terms of road safety. Since subsequent waves of COVID-19 cases and other pandemics may reappear in the future, the outcomes of the current study may be exploited for the improvement of road safety from local authorities and policymakers. doi

Investigation of the effect of pandemic restriction measures in European mobility using clustering and machine learning classification, July 2021

An NTUA Diploma Thesis titled “Investigation of the effect of pandemic restriction measures in European mobility using clustering and machine learning classification” was recently presented by Dimitra Pigadioti. This Diploma Thesis revealed that the population’s behavior towards the pandemic and the consequent deaths, are better reflected and predicted by the characteristics of the population movements and not by the number of COVID-19 cases. Furthermore, the population’s mobility trends during the pandemic can be predicted satisfactorily for most European countries, considering the data of new COVID-19 cases per million population, the implemented vaccination policies and the movement trends to the grocery, pharmacy and parks. pdf5 ppt5

Comparative analysis of road safety factors across generations, in Greece, July 2021

An NTUA Diploma Thesis titled “Comparative analysis of road safety factors across generations, in Greece” was recently presented by Reggina Mermiga. From the application of Log-Linear regression models it emerges that the number of road casualties follows a rising trend in the transition from the older to the younger generations, which presumably can be attributed to increased mobility of younger generations. Additionally, most car crash victims between the ages of 26 and 64 belong to Generation X while those involved in a two-wheeled vehicle accident belong to Generation Y, most probably due to the fact that the members of the two generations are connected to different financial periods but also to the tendency of the members of Generation Y to experience delays in their transition to the following stages of their life. pdf5 ppt5

Which factors lead to driving errors? A structural equation model analysis through a driving simulator experiment, April 2019

A paper titled “Which factors lead to driving errors? A structural equation model analysis through a driving simulator experiment” authored by Panagiotis PapantoniouGeorge Yannis and Eleni Christofa is published in Journal of IATSS. Data were obtained from a driving simulation experiment in which 95 participants covering all ages were asked to drive under different types of distraction (no distraction, conversation with passenger, cell phone use) in rural and urban road environment, as well as in both low and high traffic conditions. Structural Equation Models were developed and the driving error was modeled as a latent variable based on several individual driving simulator parameters. The results of this complex model reveal that the impact of driver characteristics and area type are the only statistically significant factors affecting the probability of driving errors. Interestingly, neither conversing with a passenger nor talking on the cell phone have a statistically significant impact on driving error behaviour which highlights the importance of the present analysis and more specifically the development of a measure that represents overall driving error behaviour instead of individual driving errors variables. doi

Time Series Analysis of Vehicle and Pedestrian Traffic in Athens, March 2021.

An NTUA Diploma Thesis titled “Time Series Analysis of Vehicle and Pedestrian Traffic in Athens” was recently presented by Nick Economou. The result of this Diploma Thesis is that from summer onwards the forecasted mobility evolution of drivers and pedestrians in Athens Great Area is lower than the observed one, which may be due to summer holidays and high temperatures during summer months in which the prediction was based. Considering the modal split on the examined roads in the center of Athens, it is observed a reduction in the use of passenger vehicles with a simultaneous increase in the use of taxis, which may be due to the adaptation of drivers to the new traffic conditions of the Panepistimiou street brought about by the Athens Great Walk pilot operation. pdf5 ppt5

Impact of weather conditions and rush on road safety, March 2021.

An NTUA Diploma Thesis titled “Impact of weather conditions and rush on road safety” was recently presented by Giota Spanou. Data of 42 young drivers were collected, from a driving simulator experiment with and without any time pressure in good weather conditions, in fog, rain, and snow. Linear and binomial logistic regression models were developed for the mean driving speed, reaction time, headway and accident probability. The application of the mathematical models showed that snow and rain lead to a significant increase in the probability of an accident. Fog increases the accident probability only in the event of a dangerous event and time pressure seems to have the same effects as snow, a fact that should concern drivers.  pdf5 ppt5
