Eva Michelaraki has successfully defended her PhD dissertation titled: Improving driver safety tolerance zone through holistic analysis of road, vehicle and behavioural risk factors, under the supervision of NTUA Prof. George Yannis.
Data from 190 drivers who participated in a large on-road and simulator
driving experiment were exploited. An innovative methodology,
consisting of both statistical analyses (Generalized Linear Models,
Structural Equation Models) and machine learning techniques (Decision
Trees, k-Nearest Neighbors, Neural Networks and Random Forests) was
implemented. Results indicated that RF models outperformed the DT and
kNN models across all metrics, making them the most effective for
predicting speeding and headway, with overall accuracy up to 90%. It was
also revealed that task complexity was positively correlated with risk, while coping capacity was negatively correlated with risk, indicating that drivers with higher coping capacity are better equipped to handle challenging driving situations.   |

The Expert Group on Urban Mobility (EGUM) of the European Commission has
recently delivered a set of Recommendations for the Commission’s
mid-term review of the EU Road Safety Policy Framework 2021-2030.
Special focus is given on active mobility and road safety for Vulnerable Road Users,
for which key risk factors and a set of Recommendations for people who
walk, cycle and use light electric vehicles, micromobility devices and
powered two-wheelers, are being provided. |

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Cyclists Thematic Report which
refers to users of a conventional bicycle or a pedelec/e-bike, i.e., an
electric powered bicycle offering pedal assistance up to approximately
25 km/h. This Thematic Report describes how cyclists participate in
traffic, as well as cyclists in relation to road safety hazards.
Furthermore, countermeasures about infrastructure, bicycle-related
measures, protective measures, enforcement and traffic education are
suggested.  |

UNECE
has introduced new Guidelines and Recommendations aimed at enhancing
cycling networks and promoting cycling as a sustainable and safe mode of
transportation. These Guidelines emphasize the need for well-connected
cycling infrastructure and the integration of cycling into national
transport systems. By prioritizing safer cycling routes, the Guidelines
aim to achieve safer, healthier and more environmentally friendly urban and rural mobility. This initiative is expected to play a key role in shaping future transport policies across Europe. |

The International Road Assessment Programme (iRAP) announced at the IRF World Congress 2024 in Istanbul, Turkey, the enhancement of the Star Rating for Designs (SR4D), a Tool that allows the safety of road designs to be measured before the commencement of civil works.
Using the Tool, road engineers and designers can define a road’s
geometry and code its features to obtain a globally recognised iRAP
safety Star Rating, along with fatal and serious injury estimations, and
safety investment plans to optimise safety. |

The European Commission is making available within the European Road Safety Observatory, the Road Safety Atlas application, exploiting data from the CARE database, the EU database with disaggregate data. It is an application openly available with several detailed thematic maps on road fatalities and
extended backround data available, including statistics per country and
comparisons between countries. It provides a user-friendly interface to
discover up to date road safety indicators for European countries. |

The E-Scooter Riders Thematic Report of the European Survey of Road Users’ Safety Attitudes (ESRA) has been published with the active contribution of NTUA, containing a
wealth of information on road safety in 39 countries across Europe,
America and Asia-Oceania, based on the ESRA3 survey. This Thematic ESRA3
Report provides an in-depth examination of road safety issues
associated with e-scooter , including an extensive analysis of
self-declared unsafe behaviours in traffic, the utilization frequency of
e-scooters, and the incidence of involvement in road crashes among
e-scooter riders. Moreover, the Report investigates determinants that may elevate the risk of crash involvement for e-scooter riders, offering a detailed perspective on the complexities of e-scooter road safety. |

The International Cooperation on Theories and Concepts in Traffic safety (ICTCT) together with the Traffic and Transportation Safety Lab of
Delft University of Technology organized with great success the 36th
Conference which was held in The Hague, Netherlands, on 17-18 October
2024. This conference with theme “Inclusive and interdisciplinary road safety research”
served as a platform for global leaders, industry experts, academia and
diverse public and private stakeholders to engage in insightful
discussions and collaborative efforts. Particular emphasis was given to
vulnerable road users, micromobility, road infrastructure design,
innovative research methodologies and inclusive road safety policies.

The Transportation Infrastructure Scientific Association of Italy (ASIT) in cooperation with the Order of Engineers of the Province of Naples organized with great success the Traffic Moderation Conference,
which was held online, on 9 October 2024. This conference aims to
provide an overview of the results of the most recent national and
European experiences related to the implementation of the speed limit of 30km/h in urban areas and traffic moderation. NTUA Professor George Yannis actively contributed with the following key-note presentation:

A NTUA Diploma Thesis titled “Impact factors of Greek drivers self-reported traffic violations”
was recently presented by Alexandros Kitsios. To fulfill this
objective, six Binary Logistic Regression models and a Structural
Equation Model (SEM) were developed using data from the second edition
of the E-Survey of Road users’ Attitudes (ESRA). The
covariance between the dependent variables of driving with alcohol
consumption above the legal limit, driving on a highway, but also inside
and outside a residential area at a speed above the legal limit, and
using a mobile phone without a headset and to access social networks
while driving, is positive and statistically significant revealing that drivers
who engage, more frequently, in one of these risky behaviors are more
likely to also engage in any of the others in combination. |

The Horizon 2020 research project PHOEBE has recently released the PHOEBE 3rd Newsletter,
which provides information on the latest outcomes of the EU-funded
‘Predictive Approaches for Safer Urban Environment’ (PHOEBE) project
aiming to increase the road safety of vulnerable road users,
especially those who use active mobility and e-scooters. Special focus
is given to the assessment of current mobility pilot plans in Athens,
carried out by NTUA. |
