Light Electric Vehicles for Muscle
Light electric vehicles (LEVs) facilitate a significant reduction in global warming potential (GWP) and other environmental impacts related to specific transport performance due to their lightweight construction. Low-voltage systems in the drive engine, an open vehicle design and online vehicle data processing allow LEVs to be repaired by independent workshops, thus enabling long vehicle use as well as conversion or retrofitting for periods of use beyond 20 years. LEVs are not yet very common in everyday life in Western Europe. In order to support the acceptance of muscle power-supported LEVs in the EU L7e registration class by users, the vehicle design and construction specifically address requirements in the areas of last-mile parcel delivery and other transport services, including passenger transport. Life cycle assessment was used to investigate two construction methods for LEVs, mixed construction and fibre composite construction, in terms of the production, service life phase and end of life. A vehicle configuration was developed which, in addition to resource-saving production and long-life operation, enables easy access for users and maintenance of the LEV for various purposes. The resource efficiency of light electric vehicles was proven with regard to the ecological aspects.

Efficiency of Mediterranean Container Ports
Container ports located in the wider Mediterranean area act as important maritime gateways connecting Europe, Asia and North Africa. They are considered as important and strategic nodes that facilitate intercontinental transport activities. Port performance is formed by a set of components, among which efficiency and effectiveness are two major interrelated ones.

Drone Scheduling for Emergency Power Material Transportation
Stable material transportation is crucial for quickly restoring power systems after disasters. Drone-based material transportation can bypass the limitations of ground transportation and reduce transportation time. However, the current UAV flight trajectory distribution optimization model cannot meet the needs of emergency relief material distribution in mountainous areas after disasters. Having a sound emergency distribution plan can significantly speed up the recovery of your distribution system.

Health Benefits of Promote Walking in Urban Areas
The transportation sector contributes significantly to global warming, as well as to urban fabric problems such as traffic congestion, traffic accidents, noise pollution, and air pollution. A shift from fossil fuels to renewable sources and from motorized to non-motorized modes is now considered essential to create sustainable communities. Walking is a sustainable transport mode and several studies have focused on factors affecting it, including travel behavior and sociodemographics.

Emitted Radiated Interference of Video Monitoring Systems
Video monitoring systems (VMSs) operated throughout an extensive railway area are responsible for the safety of people and property transport processes. Emissions of radiated electromagnetic interference generated in an unintended manner by traction vehicles within a railway line lead to interference in the VMS operating process. Based on the knowledge of actual VMS operating process data, spectral characteristics and values of individual components of disturbing signals occurring in the emissions of radiated electromagnetic interference, it is possible to determine the parameters of damage intensities for the devices and elements of this system. Using that data enables determining the VMS reliability parameters within its operating system, for an extensive railway area.

Methodology of Transport Corridor Modeling Using Petri Nets
Current models for evaluating sustainable transport corridors often lack a comprehensive framework capturing the multifaceted performance measures vital for holistic assessment especially at the early stages of operation, when detailed information on the performance indicators of these transport corridors is not available. This gap motivates a Petri net-based modeling approach that integrates key sustainability indicators into a flexible simulation tool.

Deficiencies of Quantitative Disaster Risk Assessment for Railway
Natural hazards constantly threaten the sustainable construction and operation of railway engineering facilities, making railway disaster risk assessment an essential approach to disaster prevention. Despite numerous studies that have focused on railway risk assessment, few have quantified specific damages, such as economic losses and human casualties. Meanwhile, the mechanism of impact damage from various disasters on railway facilities and the propagation of functional failure in railway systems have not been thoroughly summarized and addressed. Thus, it is essential to conduct effective quantitative risk assessments (QRAs) to facilitate the sustainable design, construction, and operation of rail infrastructure.

Smart Cities and Public Transport Vehicles
A “smart city” contains not only new tools but also vehicles or infrastructure. A new type of vehicle could use both the existing tram routes and newly constructed sections with no tracks. It is assumed that new vehicles would drive with trams on the same, shared tracks.

Analysis of Following Vehicles’ Driving Patterns
Despite the potential benefits of autonomous vehicles (AVs) of reducing human driver errors and enhancing traffic safety, a comprehensive evaluation of recent AV collision data reveals a concerning trend of rear-end collisions caused by following vehicles. Developing a methodology that identifies the relationship between driving patterns and the risk of collision between leading and following vehicles using spectral analysis can address this issue. Specifically, a process is proposed for computing three indices: reaction time, stimulus compliance index, and collision-risk aversion index. These indices consistently produced reliable results under various traffic conditions. The findings align with existing research on the driving patterns of following vehicles. Given the consistency and robustness of these indices, they can be effectively utilized in advanced driver assistance systems or incorporated into AVs to assess the likelihood of collision risk posed by following vehicles and develop safer driving strategies accordingly.

Flight Safety Assessment Based on Quick Access Recorder
The QAR (quick access recorder), as an airborne data recorder, can collect and store multidimensional flight parameter data during a flight. Currently, QAR devices have been widely installed on various types of aircraft. It has been proven by practical experience that the QAR can effectively collect thousands of real-time parameters during flight. These flight parameters can reflect the condition of the external environment, flight attitude, aircraft status, pilot operations, etc. Therefore, they provide objective evidence for flight technical evaluations, safety incident investigations, and the elimination of potential flight safety hazards, which can yield better flight safety.
