  In-vehicle vision

  Over the past two decades, the reduction of accidents and fatalities has been achieved in part through the implementation of ADAS. These onboard safety functions rely primarily on the use of exteroceptive vision sensors. To improve the performance and robustness of ADAS, new sensor technologies such as neuromorphic, polarized, and HDR cameras have been developed. These sensors, whether used individually or in combination, enable real-time perception of road scenes, which is essential for the development of new automated mobility solutions. This article provides an overview of these embedded vision sensor technologies, their applications, limitations, and future prospects.

  AI for environmental perception in automobiles

  Automated mobility increasingly relies on perception systems that are expected to be reliable, robust, and resilient. These systems, whether embedded in the vehicle or deployed in the infrastructure, combine various sensors and, more and more, AI-based algorithms. Their main goals consist to estimate the current state of the road scene key components to generate local dynamic perception maps, which are essential for ADAS. These functions have become critical, as they no longer only provide information (advice, warning) but now enable decision-making and influence the vehicle’s dynamic behaviour. This article summarizes the current state of these perception systems, their applications, and limitations, while exploring the impact of these emerging AI-powered technologies.

  Particulate emissions from tire/road interaction

  Fine particle pollution causes over 350,000 premature deaths per year in the EU. Despite the advent of the electric vehicles, emissions of non-exhaust particles (NEP) from transport, particularly those generated by tire-road wear (TRWP), will persist. These emissions are likely to affect public health, causing allergic reactions and respiratory disorders. This article presents the issues and challenges involved in studying TRWP emissions, in particular the variability of their mass granulometry. Finally, a solution for comparing these mass-weighted distributions of TRWP collected on different types of road will be presented via an in-situ study.

  Thermal engines and the challenges of climate change

  Thermal engines have dominated sectors of economy, and particularly transportation. Their current development and state of the art are the results of XXth century priorities related to economy and environment. In the future, thermal engines will face the challenge of emerging technologies in the frame of sustainable mobility and development. After an analysis of functioning principles and perspectives of development, particularly of combustion engines, thermal engines are compared to other realistic scenarios for transports applications in well-to-wheel and life cycle analysis.

  Tires for the energy transition

  Tires play a significant role in the energy consumption of the vehicles they are mounted on. This article begins with a presentation of tire environmental impact analysis, carried out using life cycle assessment method. Then, mechanisms responsible for rolling resistance are detailed, both at micro and macroscopic scales. Last section is dedicated to norms and regulations related to tire energy efficiency, as well as the link between tire rolling resistance and vehicle fuel consumption.

  TRP1004 Review

  Building sustainable and inclusive mobility through education

  In the field of mobility, the leading sector for greenhouse gas emissions in Europe, a world that is a prisoner of travel, transport and the automobile will be neither sustainable nor inclusive. The constant drive to go faster, further and more often is leading us into a dead end. In this article, the authors address these issues by redefining the notion of mobility, and demonstrate that education is essential to make travel more sustainable and inclusive for individuals and communities. They then draw up a precise framework for a commitment of companies to ensure that mobility, based on education, can generate the metamorphoses that give meaning to the life of each individual without exhausting the planet's resources.

  Vehicle selection decision support

  The purchase of a vehicle is a complex decision linked to several economic, legislative, ecological, and environmental constraints. This article presents the Crit'Air certificates, low emission zones, as well as the major challenges of electrification and biofuels to reduce greenhouse gases and pollutants from road vehicles. The article introduces the tools for annual ownership cost and greenhouse gas emissions assessment from well to wheel, in order to compare different fuels, energy sources, and technologies. Finally, two use cases are presented for a heavy-duty truck and a light commercial vehicle such as a van.

  SPI-SHS dialogue on the socio-technical challenge of hydrogen mobility

  Face to the carbon mobility model limitations, this paper analyses the process of the transition to an hydrogen fuel cells mobility, through the prism of the human and social sciences. This sciences highlight the process of emergence of a new mobility paradigm and factors locking the diffusion of fuel cell-hydrogen technologies in the mobility system. Bringing them closer to the engineering sciences is essential because of the systemic nature of the transformations required for the socio-technical mobility system.

  Eco-driving and cars

  This article aims to detail several aspects of eco driving. After providing a definition, long term benefits of eco-driving training will be presented. Then, it gives order of magnitude of the asymptotic theoretical efficiency potential as optimal driving, before analyzing tools implemented into cars leading the driver to adopt an eco driver behavior. Finally, this article reviews technologies’ evolution perspective towards more and more autonomous and efficient driving and will explain the global potential for the society.

  Aerial cable transportation in cities: relevance and implementation issues

  This article deals with the more complex than expected implementation of aerial cable transportation systems in French and European cities. Aerial ropeways are characterized by a wide variety of configurations, enabling a vast range of services to be provided. Their hourly capacities can be equivalent to those of BRTs or even streetcars. Only the length of the lines (combined with the number of changes of direction on the route) can be a handicap, as peak speeds are slightly lower. However, for a variety of reasons, such as underestimation of the cost of adapting to the urban environment, or fears of visual or noise pollution, this more flexible mode is still struggling to win people over.
