Intelligent Transport Systems
Intelligent transport systems enable vehicles to communicate with each other and with the environment, ensuring road safety. Their implementation can help reduce the number of accidents, especially in stretches of s-curves, where speed control is essential to ensure the safety of drivers, and under hazardous weather conditions. Such systems promptly notify drivers about potentially dangerous road conditions, such as fog, so that they can better adapt their driving behavior.

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.

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.

Longwall Mining Automation
The shearer positioning method is of great significance to the automation of longwall mining. The research teams in the Longwall Automation Steering Committee (LASC) of Australia and China University of Mining and Technology (CUMT) have focused on shearer positioning and identified the shearer inertial navigation system, the measurement of longwall retreat and creep displacement, and the backward calibration of the shearer trajectory as three key technologies to obtain accurate shearer positioning information.

M-Bahn
The M-Bahn or Magnetbahn was an elevated Maglev train line operating in Berlin, Germany , experimentally from 1984 and in passenger operation from 1989 to 1991. The line was 1.6 kilometres (1 mi) in length, and featured three stations, two of which were newly constructed. Presumed to be the future of rail transit in Berlin, the line was built to fill a gap in the West Berlin public transport network created by the construction of the Berlin Wall. It was rendered redundant by the reunification of Berlin and was closed to enable reconstruction of the U2 line. The M-Bahn was the second Maglev line to open to public traffic, after the Birmingham Maglev but before the Shanghai maglev train. Construction and running were undertaken by Magnetbahn GmbH.

Machine Learning in Aviation Environmental Impact Analysis
The rapid growth of global aviation operations has made its negative environmental impact an international concern. Accurate modeling of aircraft fuel burn, emissions, and noise is the prerequisite for informing new operational procedures, technologies, and policies towards a more sustainable future of aviation. Due to the advances in big data technologies and effective algorithms, the transformative data-driven analysis has begun to play a substantial role in aviation environmental impact analysis. The integration of statistical and machine learning methods in the workflow has made such analysis more efficient and accurate.

Manual on Uniform Traffic Control Devices
The Manual on Uniform Traffic Control Devices for Streets and Highways (usually referred to as the Manual on Uniform Traffic Control Devices, abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. These specifications include the shapes, colors, and fonts used in road markings and signs. In the United States , all traffic control devices must legally conform to these standards. The manual is used by state and local agencies as well as private construction firms to ensure that the traffic control devices they use conform to the national standard. While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD. The National Committee on Uniform Traffic Control Devices (NCUTCD) advises the FHWA on additions, revisions, and changes to the MUTCD. The United States is among the many countries that have not ratified the Vienna Convention on Road Signs and Signals. The first edition of the MUTCD was published in 1935, 33 years before the Vienna Convention was signed in 1968. The MUTCD differs significantly from the European-influenced Vienna Convention, and an attempt to adopt several of the Vienna Convention's standards during the 1970s led to confusion among many American drivers.

Marine Safety in Relation to Human Errors
As in any industry exposed to risk, human and organizational factors are the main stakes of maritime safety. Understanding the causes and risks of maritime accidents is integral to the sustainability of shipping. The investigation of marine accidents is a crucial tool for their identification in areas related to operations and ships.
