Public Acceptability of Environmentally Linked Congestion and Parking Charging Policies in Greek Urban Centers, July 2022
A paper titled “Public Acceptability of Environmentally Linked Congestion and Parking Charging Policies in Greek Urban Centers” authored by Virginia Petraki, Panagiotis Papantoniou, Asimina Korentzelou and George Yannis, is published in Sustainability. A structural equation model (SEM) was developed using data from a questionnaire survey which provided a sample encompassing 733 respondent drivers from three main urban centers of Greece: Athens, Thessaloniki and Volos. Several statistical relationships were detected and quantified correlating the two examined urban environmental charging policies with five latent unobserved variables. Based on the results, public acceptability of environmental congestion charging policies and the public acceptability of environmental parking charging policies were found to be positively correlated with each other, meaning that a driver who supports one environmentally linked transport charging policy is more likely to support the other one as well.
Data-driven estimation of a driving safety tolerance zone using imbalanced machine learning, July 2022
A paper titled “Data-driven estimation of a driving safety tolerance zone using imbalanced machine learning” authored by Thodoris Garefalakis, Christos Katrakazas and George Yannis, is published in Sensors 2022. This paper proposes a framework to identify the level of risky driving behavior as well as the duration of the time spent in each risk level by private car drivers. The results showed that RF and MLP outperformed the rest of the classifiers with 84% and 82% overall accuracy, respectively, and that the maximum speed of the vehicle during a 30 s interval, is the most crucial predictor for identifying the driving time at each safety level.

This year’s event provided the opportunity to discuss and shape new solutions to strengthen Europe’s resilience and its strategic autonomy.
An NTUA Diploma Thesis titled “Analysis of speeding characteristics in Greece” was recently presented by Spyridon Krouskos. The data used for the statistical analysis were collected in the period of November-December of 2021 in Greece, and were related to vehicle speed measurements, but also to the simultaneous recording of the type of vehicle, the type of road, the weather conditions and the time period. The results showed that motorcycle drivers are more likely to exceed the speed limit than passenger car drivers, while it was estimated that the opposite is true for the other types of vehicles. It was also found that drivers on urban roads are more likely to exceed speed limits than drivers on motorways.
Detection of dangerous driver behavior with widescale data from smart recording systems and machine learning techniques, July 2022
An NTUA Diploma Thesis titled “Detection of dangerous driver behavior with widescale data from smart recording systems and machine learning techniques” was recently presented by Hector Kamvoussioras. The data was collected from a large database created through a simulation experiment conducted within the European H2020 project. Three categories of driving were extracted from the data: normal driving, dangerous driving and avoidable accident. The three categories were extracted using maximum speed as the concerned variable and checking whether drivers exceeded the speed limit through it.
The Urban Mobility Days Conference 2022, co-organised by the European Commission, Directorate-General for Mobility & Transport (DG MOVE) and the Czech Presidency of the Council of the EU was held with great success in the city of Brno (Czech Republic) on 20-22 September 2022. Urban Mobility Days provides a unique forum for policymakers, local authorities, academics, NGOs, urban transport practitioners, and urban planners to connect and discuss the way forward for a sustainable, innovative, and equitable future for Europe’s urban mobility. This year’s theme was “Moving people and goods more sustainably”.
An NTUA Diploma Thesis titled “Comparative analysis of socioeconomic indicators on road safety in the Greek Regions” was recently presented by Nikolaos Papadopoulos. A cluster analysis was performed leading to four clusters: Islands, Western & Southern mainland Greece, Northern mainland Greece and Attica. The results depicted the different geographical characteristics, economic level, mobility patterns and road behaviors of the regions, which are also reflected in road safety outcomes.

Identification of driver’s risky behavior level and duration with machine learning techniques, March 2022
An NTUA Diploma Thesis called “Identification of driver’s risky behavior level and duration with machine learning techniques” was recently presented by Theodoros Garefalakis. For the purpose of this Diploma Thesis, high resolution data related to driving behavior were collected through a driving simulator experiment. In the first part of the analysis, four machine learning algorithms were developed to classify driver behavior into one of three risk levels, with the ‘Random Forests’ algorithm scoring the highest performance. In the context of investigating the influence of driving factors to identify driving behavior, the distance traveled, speed and speed limit emerged as the most important. In the second part of the analysis, the effect of driving characteristics on driving duration at different stages was examined through three regression algorithms. The results showed that the maximum speed was the most important variable, which negatively affects the driving duration at each safety level.
Impact of Pandemic on National and International Air Transport Demand at Athens International Airport, March 2022
An NTUA Diploma Thesis called “Impact of Pandemic on National and International Air Transport Demand at Athens International Airport” was recently presented by Stamatios Tsakoulis. This Diploma Thesis investigated the factors of the pandemic that influenced the air transport demand at Athens Airport and revealed that the rate of vaccination coverage of the population is the most critical variable of recovery of air traffic while the severity of the lockdown is an important inhibitory factor. In addition to that, low-cost airlines showed the highest correlation with air traffic, while airlines with chartered flights in countries with temporary traffic had a significant influence.
An NTUA Diploma Thesis called “Free Public Transport in Attica Region” was recently presented by Vaggelis Goulas. This Diploma Thesis revealed that the possibility of changing means of free public transport depends largely on the cost, time, comfort, beliefs, transportation characteristics and demographic characteristics of the respondents. The faster and more comfortable the journey, regardless of cost reduction, the more likely it is to opt for free public transport instead of staying in the existing means of transport.
A paper titled “Impact of texting and web surfing on driving behavior and safety in rural roads” authored by Marios Sekadakis, Foteini Orfanou, Dimosthenis Pavlou, Maria Oikonomou, Christos Katrakazas and George Yannis, is published in International Journal of Transportation Science and Technology. For the purpose of the study, driving data were gathered through a driving simulator experiment with 37 young drivers. Additionally, a survey was conducted to collect their demographic characteristics and driving behavior preferences. During the experiment, the drivers were distracted using contemporary smartphone internet applications i.e., Facebook Messenger, Facebook and Google Maps. In the end, the results showed that driving behavior and safety among young drivers were both significantly affected by the investigated internet applications.
