Results and lessons learned of a subjective field operational test on the lane departure warning function

The paper presents the preliminary results and the lessons learned from the Italian Field Operational Test on the Lane Departure Warning (LDW) function that is being carried out within the European project euroFOT. The FOT has deployed a large scale subjective test involving a sample of 570 drivers and using a wide and differentiated set of self-reported questionnaires about system usage and impact. The purpose of the FOT is to investigate the subjective aspects about LDW system users' acceptance and the perceived impact of the LDW system on safety, driving behaviour and transport-related aspects. Results are expected to accurately depict the actual impact of this function based on subjective data

Development of a methodology and tool to evaluate the impact of ICT measures on road transport emissions

The paper presents the main elements of a project entitled ICT-Emissions that aims at developing a novel methodology to evaluate the impact of ICT-related measures on mobility, vehicle energy consumption and CO2 emissions of vehicle fleets at the local scale, in order to promote the wider application of the most appropriate ICT measures. The proposed methodology combines traffic and emission modelling at micro and macro scales. These will be linked with interfaces and submodules which will be specifically designed and developed. A number of sources are available to the consortium to obtain the necessary input data. Also, experimental campaigns are offered to fill in gaps of information in traffic and emission patterns. The application of the methodology will be demonstrated using commercially available software. However, the methodology is developed in such a way as to enable its implementation by a variety of emission and traffic models. Particular emphasis is given to (a) the correct estimation of driver behaviour, as a result of traffic-related ICT measures, (b) the coverage of a large number of current vehicle technologies, including ICT systems, and (c) near future technologies such as hybrid, plug-in hybrids, and electric vehicles. The innovative combination of traffic, driver, and emission models produces a versatile toolbox that can simulate the impact on energy and CO2 of infrastructure measures (traffic management, dynamic traffic signs, etc.), driver assistance systems and ecosolutions (speed/cruise control, start/stop systems, etc.) or a combination of measures (cooperative systems).The methodology is validated by application in the Turin area and its capacity is further demonstrated by application in real world conditions in Madrid and Rome

Safety-Related Cooperative, Connected, and Automated Mobility Services: Interplay Between Functional and Security Requirements

Together with the electrification of vehicles, the provision of cooperative, connected, and automated mobility (CCAM) services is a prominent recent trend in the automotive sector. Upcoming car models will be able to exchange messages between themselves and with road traffic authorities by means of vehicle-to-everything (V2X) communication – in particular, leveraging mobile network technologies for the so-called cellular V2X (C-V2X) paradigm. Moreover, (part of) such exchanged messages will be processed as a whole in, e.g., edge computing servers, in order to generate a global vision of the state of a given road stretch. CCAM services will exploit vehicular information transport and processing to implement complex maneuvers in a (semi)automatic manner by interacting with the in-car network. The undeniable benefits of CCAM services should be coupled with their security, though. Proper protection mechanisms of V2X communication as well as of edge processing must be put in place with the ultimate scope of ensuring the security of car’s critical functions such as e.g., driver assistance, collision warning, and automatic emergency braking. As a matter of fact, according to the ongoing discussions in the European Union (EU) and United Nations Economic Commission for Europe (UNECE), all new vehicle models will be approved only if they fulfill the cybersecurity requirements of the General Safety Regulation starting July 6, 2022. In this article, we will overview the major standards in terms of automotive security specifications, specifically focusing on those related to the external connectivity of cars. Moreover, since not all threats may be caught at a specification level, we will perform a qualitative security assessment of safetyrelated CCAM services featured by the EU-funded project 5G-CARMEN, with the final aim of highlighting the delicate interplay between functional and security requirements
