The European Commission with the active contribution of NTUA, SWOV and KFV has launched a safe mobility promotion activity focusing on helmets, seatbelts and child restraint systems. According to the new Reports from the European Road Safety Observatory, protective equipment has been shown to be very effective in protecting road users from death or serious injuries. If used correctly, motorcycle helmets can reduce fatal crashes by around 40% and the chance of severe head injury by almost 70%. Seatbelts are shown to reduce the risk of fatal incidents by 60% for occupants in the front of a vehicle and 44% for those in the rear. Regarding child restraint systems, research indicates that children who are correctly restrained are around 60% less likely to be killed or injured compared to unrestrained children.

A paper titled “Leveraging Machine Learning Algorithms to Predict and Analyze Single-Vehicle and Multi-Vehicle Crash Occurrences on Motorways” authored by Saumik Sakib Bin Masud, Kirti Mahajan, Alexandra Kondyli, Katerina Deliali and George Yannis has been published in Transportation Research Record. The dataset for this research included various types of roadway design parameters and traffic conditions. Combinations of three feature-selection techniques, namely ANOVA, correlation matrix, and ExtraTreesClassifier algorithm, were utilized to separately select the appropriate variables for single-vehicle (SV) and multi-vehicle (MV) crash analysis. The results confirmed that the crash factors associated with single and multi-vehicle crashes are different and that some parameters have inverse impact. Artificial intelligence and Machine Learning (ML) can assist transportation professionals in better understanding the causes of SV and MV crashes and advance the process toward Vision Zero. ![doi](https://www.nrso.ntua.gr/wp-content/uploads/DOI.png)

Eurostat has recently released a progress Report titled ‘Sustainable development in the European Union – monitoring report on progress towards the SDGs in an EU context – 2024 edition’. This publication provides readers with a statistical overview of the EU’s progress towards its Sustainable Development Goals (SDGs). Based on the assessment of the past five years of available data, the EU made progress towards most of the SDGs, while it fell slightly behind in a few goals. Specifically for road safety, the EU road safety policy framework 2021–2030 and Sustainable and Smart Mobility Strategy aim to reduce deaths and serious injuries on the road by 50% by 2030.

The Royal Society for the Prevention of Accidents (RoSPA) has recently published a Synthesis Report titled “Speed Limits” which focuses on the interventions regarding effective speed management. More precisely, new principles about setting speed limits are emerging, based on an assessment of the combined risk relating to the infrastructure, travel speeds, volume and mix of traffic by type (including vulnerable road users). Furthermore, signs are the primary way of communicating the speed limit of a road to drivers, with principles of effective speed limits signing been uniformity, consistency, simplicity, relevance and legibility. ![](https://www.nrso.ntua.gr/wp-content/uploads/LINK.png)

The Royal Society for the Prevention of Accidents (RoSPA) has recently published a Synthesis Report titled “Speed” which focuses on the relationship between speed and risk. Precisely, as average traffic speed reduces, so does the likelihood of a crash resulting in injury that is recorded by the police. Furthermore, effective speed management policies are likely to include an integrated package of measures, including credible speed limits, enforcement, education and engineering. RoSPA is a leading voice in health and safety that has campaigns to reduce avoidable crashes on the road. ![](https://www.nrso.ntua.gr/wp-content/uploads/LINK.png)

BBC World News published an article about a revolutionary idea that changed the way Europe regarded road collisions. Claes Tingvall, as the head of Road Safety for the Swedish Road Adminstration in 1995, tried to balance road safety with other factors, including cost, driver preferences and the impact on the economy of changing traffic flows. Tingvall found that crash victims were not, as many in the road transport sector, assumed – drunk and irresponsible drivers but for the most part, they were people who made small mistakes. He introduced the Vision Zero fatalities as ultimum target and the Safe System approach as the way to share the responsibility also to the Authorities and all those involved in the design and the operation of the road and traffic system to be preventive and forgiving to human errors, eliminating the crash and injury risk. ![link](https://www.nrso.ntua.gr/wp-content/uploads/LINK.png)

Dimitris Nikolaou has successfully defended his PhD dissertation titled: Machine learning-based road crash risk assessment fusing infrastructure, traffic and driver behaviour data, under the supervisoon of NTUA Prof. George Yannis. Τwo distinct databases were developed; the first one concerned motorway segments and included road crash, traffic, road geometry and driver behaviour data (OSeven telematics), while the second database concerned urban and interurban road segments of a broader area. The results revealed that crash frequency on motorway segments is positively correlated with the traffic volume, the segment length, the number of harsh accelerations and the number of harsh brakings per segment trips. Furthermore, it was concluded that harsh brakings can serve as a valid subcategory of Surrogate Safety Measures under naturalistic driving conditions, which can be used as the dependent variable either in proactive road safety analyses or in cases where detailed crash data are unavailable. It was found that harsh brakings were positively correlated with road segment length, number of trips per segment, speeding and mobile phone use.

An NTUA Diploma Thesis titled “Model for the assessment of cycling routes in Athens with high resolution data” was recently presented by Aristeidis-Vasileios Kanakis. For this purpose, the critical factors that influence the cycling trips carried out in the areas of Chalandri and Vrilissia, utilizing crowdsourced data from the “Strava Metro” platform, were identified. The results demonstrate a positive effect of the average speed of cycling on the number of cycling trips. The most critical influencing factors on cycling trips concern road infrastructure and traffic conditions on each road section, such as the average speed of cycling trips, the category of road section and its length.

An NTUA Diploma Thesis titled “The influence of the penetration of autonomous vehicles on road safety” was recently presented by Antonia Antonakaki. For this purpose, an analysis of simulation data was carried out around the Villaverde network in Madrid. The application of the models revealed that the factors influencing the above variables have to do with both traffic composition data (vehicle type) and road infrastructure data (road type, road capacity). It is highlighted that increasing the Market Penetration Rate (MPR) of autonomous vehicles in the network was found to have, quantifiable positive effects on road safety.

An NTUA Diploma Thesis titled “Investigation of employee preferences in Athens towards the “Bike to Work” scheme” was recently presented by Konstantinos Aggelakis. In order to achieve this, factors influencing the decisions of workers to use a soft mode of transportation such as bicycles and scooters (electric or conventional) for their commutes in Athens are examined, as well as how the existence of a bicycle lane network affects this decision. Polynomial models demonstrate that increased time and cost savings in commuting do not significantly affect the choice of bicycle or scooter as a commuting mode, contrary to health improvement, while commute duration and commuter age are also significant factors in the choice of micro-mobility modes.

The International Transport Forum (ITF) has recently published a new Report titled “Safer Micromobility“ co-authored by George Yannis, Virginia Petraki and Philippe Crist. This Report examines safety aspects associated with the increasing use of e-scooters and other forms of micromobility in cities. Micromobility is becoming safer (per miles driven), but an increase in severe injuries from e-scooter crashes is cause for concern. The Report considers a comprehensive set of recommendations in line with the Safe System Approach, to make urban traffic with micromobility safe, including in street layout, vehicle design and vehicle operation, user education and enforcement of rules. It also asks whether a shift towards micromobility can have potential overall traffic safety benefits.
