Energy-Efficient Driving
The transportation sector remains a major contributor to greenhouse gas emissions. The understanding of energy-efficient driving behaviors and utilization of energy-efficient driving strategies are essential to reduce vehicles’ fuel consumption. However, there is no comprehensive investigation into energy-efficient driving behaviors and strategies. Furthermore, many state-of-the-art AI models have been applied for the analysis of eco-friendly driving styles, but no overview is available.

New Mobility Agenda
The New Mobility Agenda is an international institution which, although a virtual and open collaborative project today, was originally set up by an international working group meeting at the Abbey de Royaumont near Paris in 1974 with the support of the Parisian OECD to challenge old ideas and practices in the field of urban transport through a long term collaborative program of information exchange, education and peer support. The Agenda today draws together the experience, expertise and support of more than four thousand individuals and groups worldwide in an open collaborative peer network. One of the original proponents of this approach, Professor Mikoto Usui then director of the OECD Development Centre, referred to it in the founding meeting at the "Abbé de Royaumont as an "invisible college". Drawing together the experience and expertise of more than four thousand individuals and groups worldwide, who are networked via a combination of websites, discussion groups and fora, and collaborative projects, the Agenda takes an approach to transportation planning, policy and practice that has gained considerable force over the last two decades—provides a leading-edge alternative to earlier (20th century) methods of looking at and providing mobility for people and goods in cities. The Agenda has received prestigious awards for its contributions, including the Stockholm Environment Challenge Prize (2000) and the World Technology Environment Award (2002). Like the sustainable transportation movement, to which it is closely related, it differs from previous methods (which in fact still dominate planning, policy, investment and operations in most parts of the world) in that it takes a global or broad systemic approach to the challenges of how to get around in cities, and is especially sensitive not only to pure transport efficiency (which traditionally is interpreted in pure engineering terms as speed and volume of vehicle throughput) but equally to matters of sustainable development, pollution and environmental impacts—including matters relating to climate change, the reduction of Greenhouse gases, resource efficiency, energy conservation, public health, both personal and public economics, overall time savings, public spaces, and quality of life in communities, including relations between people in public spaces – with particular attention to social justice and the unmet needs of women, children, and others with mobility or economic or health disadvantages which are not being properly served in our present mainly car-based systems and thinking, in which other forms of transport, including public transport, play only residual roles.

Energy-Saving Operational Strategies for Urban Rail Transit System
Designing low-carbon urban rail transit systems is a critical component of reducing emissions and addressing climate change at the urban scale. Energy-saving operational strategies have been investigated in two major ways: the utilization of the potential gravitational energy of a train and the flexibility of control conditions.

Enhancing Walking Accessibility in Urban Transportation
The rise in “urban diseases” like population density, traffic congestion, and environmental pollution has renewed attention to urban livability. Walkability, a critical measure of pedestrian friendliness, has gained prominence in urban and transportation planning.

BSafe-360
The popularity of bicycles as a mode of transportation has been steadily increasing. However, concerns about cyclist safety persist due to a need for comprehensive data. This data scarcity hinders accurate assessment of bicycle safety and identification of factors that contribute to the occurrence and severity of bicycle collisions in urban environments. The BSafe-360, a novel multi-sensor device designed as a data acquisition system (DAS) for collecting naturalistic cycling data, which provides a high granularity of cyclist behavior and interactions with other road users.

Static Configuration in Urban Rail Transit
With the rapid development of urban rail transit, the traditional urban rail wireless network based on fixed infrastructure is not in a position to meet the increasingly complex communication demand. At the same time, Ad Hoc network, as a special wireless mobile network, is developing rapidly. Applying this self-organized networking architecture to the urban rail vehicle–ground communication network can overcome the problems existing in the traditional urban rail communication system. The routing protocols that can achieve low delay and highly reliable data transmission are important in the urban rail transit scenario.

Quantifying Road Transport Resilience to Emergencies
The resilience of road passenger and freight transport differs in the face of external disturbance. Freight transport resilience is better than that of passenger transport. Compared to passenger transport, freight transport is more robust; the impacted speed is slower, the recovery speed is faster, the recovery capacity is stronger, and the affected period is shorter. There is regional heterogeneity in road transport resilience. This heterogeneity is reflected in the whole change process of system performance with external disturbance, including absorption capacity, adaptation capacity, and recovery capacity. The resilience of road transport under different waves of the epidemic is different. Compared to the first wave of the epidemic, the resilience of road transport indicators at all stages has been dramatically improved in the later rebound wave of the epidemic. This can help in the development of evidence-based road transport sustainability strategies.

Olea europea and By-Products: Extraction Methods/Cosmetic Applications
The olive oil industry produces vast quantities of by-products, such as olive mill wastewater, olive pomace and leaves from which new ingredients may be obtained for cosmetic use. In this way, by-products are revalorized, which contributes to the implementation of a sustainable economy or upcycling.

Krauss-Maffei Transurban
Krauss-Maffei's Transurban was a 12-passenger automated guideway transit (AGT) mass transit system based on a maglev guideway. Development started in 1970 as one of the many AGT and PRT projects that followed in the wake of the HUD reports of 1968. Its selection as the basis of the GO-Urban system in Toronto in 1973 made it well known in the industry; it would have been the basis of the first large-area AGT mass transit network in the world. Technical problems cropped up during the construction of the test track, and the sudden removal of funding by the West German government led to the project's cancellation in late 1974. The Ontario government completed development and installation of a non-maglev version, today known as the Bombardier Advanced Rapid Transit.

Emissions, Decarbonization, and Alternative Fuels in Inland Navigation
In response to the pressing need for transportation decarbonization, the often overlooked domain of inland waterway transport and seeks to answer which alternative fuel or power source is the most promising for that sector. As the shipping industry significantly contributes to global carbon emissions, it has been shifting towards alternative fuels and decarbonization measures in the effort to reduce them, whereas the inland waterways, operating predominantly on diesel engines, have not achieved equivalent substantial progress. Liquified natural gas (LNG) initially emerged as a favored alternative fuel, but recent studies emphasize a shift towards “greener” solutions like batteries and hydrogen. Europe and Asia lead in these developments. This investigation uncovers critical gaps in research and development, particularly in the Northern European countries that have extensive inland waterway networks. It also calls for future studies to explore the performance of vessels that have adopted LNG compared to other emerging alternatives and emphasizes the importance of considering the time lag between technology development and research publication.
