Classifying Travel Mode Choice through Adjustable SVM Model
The investigation of travel mode choice is an essential task in transport planning and policymaking for predicting travel demands. Typically, mode choice datasets are imbalanced and learning from such datasets is challenging. This study deals with imbalanced mode choice data by developing an algorithm (SVMAK) based on a support vector machine model and the theory of adjusting kernel scaling.

Refrigerated Transport
The cold chain is responsible for perishable products preservation and transportation, maintaining a proper temperature to slow biological decay processes. Often the efficiency of the cold chain is less than ideal, significantly increasing food waste and energy consumption. Refrigerated transport is a critical phase of the cold chain because of its negative impact on energy consumption and greenhouse gas emissions.

Roundabout
Challenges that emerge in roundabout design are mostly related to space constrictions and provision of appropriate deflection around the central island. This can result in speed profiles on roundabouts that might reduce their potential as a noise abatement measure. Because of this, the impact of a roundabout on noise levels and its applicability as a traffic calming device and a noise abatement measure should be investigated in the early design stage, by modeling noise levels.

Supply Chain and Digital Twins
The supply chains shaping their distribution networks become more diverse as companies respond to global markets’ stringent criteria. This is also counterproductive to the visibility of the supply chain within the company and can adversely affect the organization’s core business.

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.

Electrification of Transportation in Islands
Electric vehicles (EVs) represent an important socio-economic development opportunity for islands and remote locations because they can lead to reduced fuel imports, electricity storage, grid services, and environmental and health benefits. This entry presents an overview of opportunities, challenges, and examples of EVs in islanded power systems, and is meant to provide background to researchers, utilities, energy offices, and other stakeholders interested in the impacts of electrification of transportation. The impact of uncontrolled EV charging on the electric grid operation is discussed, as well as several mitigation strategies.

Passenger-like Container Train
The passenger-like container train is a fixed marshalling and fixed bottom. It does not dismantle and the marshalling station operates during the operation process. It has a definite departure and final station. Different trains will choose different stopping methods according to the different terminal stations of the transported containers. At the stopping stations, the fast loading and unloading mode of the arrival and departure line is adopted, and the containers can wait for the train at the platform like passengers and carry out loading, unloading, and reloading operations.

A Review of Description Languages and Systems
Testing and validation of the functionalities and safety of automated vehicles shifted from a distance-based to a scenario-based method in the past decade. A number of domain-specific languages and systems were developed to support scenario-based testing.

Urban Electromobility
The growing need for electric energy is forcing the construction industry to greater integrate energy production systems based on renewable energy sources. The energy ought to be used not only to support functions of the building but also to charge electric vehicles, whose number has been increasing for the last few years.

Trend towards Helmet Usage
It has been observed that cyclists wearing helmets may follow zigzag patterns while wearing helmets, which may cause accidents. Moreover, it has been observed that cyclists wearing helmets may be more responsible regarding traffic rules. These problems should be considered in creating effective traffic safety campaigns and policy making.

Traffic Stream Analysis by Radar Sensors
Traffic flow measurement technologies, such as detection stations, radar guns, or video cameras, have been used over the years to detect the level of traffic and the operating conditions. This type of sensor can record a large amount of data which is useful to evaluate and monitor road traffic conditions, and it is possible to identify free-moving and constrained vehicles by processing the collected data.

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.

Risk Management Methodology for Transport Infrastructure Security
The development of transport infrastructure is associated with risks, expressed in the likelihood of harm to the road users’ health during road accidents and their consequences. The risk management process is aimed at reducing the influence of factors that contribute to the occurrence of an accident and increase the consequences’ severity after it.

Splitter-Island on Pedestrian Safety at Roundabout
Traffic accident statistics have traditionally been used to assess traffic safety. This method has severe limitations when used to investigate the impact of a particular feature of traffic facilities on safety at a microscopic level. Most previous research on surrogate safety measures (SSMs) had, on the other hand, focused on studying the safety of traffic operation conditions.

Autonomous Vehicles Affect Traffic Conditions in Mixed Traffic
Different methodologies are being used to study the effects of autonomous vehicles (AVs) in mixed traffic to exhibit the interactions between autonomous and human-driven vehicles (HVs). Microscopic simulation tools are popular in such an assessment, as they offer the possibility to experiment in economical, robust, and optimistic ways. A lack of reliable real-world data (also known as natural data) to calibrate and evaluate the connected autonomous vehicle (CAV) simulation model is a major challenge.

Public Transport COVID-19-Safe: New Barriers and Policies
The COVID-19 emergency forced cities worldwide to adopt measures to restrict travel and implement new urban public transport solutions. The discontinuity and reduction of services made users recognize public transport systems as contamination vectors, and the decrease in the number of passengers can already be seen in several places. Countermeasures that reduce the contact with other passengers—directly (limit the number of passengers in vehicles) or indirectly (operate with large vehicles)—and increase offers are possible solutions to make users feel safe while riding.

APTs Applications in Non-Pavement Research
Accelerated pavement testing (APT) facilities are traditionally used for pavement evaluation under in-service conditions of traffic, environment, and other pavement design parameters. “APT is defined as the controlled application of a prototype wheel loading, at or above the appropriate legal load limit to a prototype or actual, layered, structural pavement system to determine pavement response and performance under a controlled, accelerated accumulation of damage in a compressed time period. The acceleration of damage is achieved by means of increased repetitions, modified loading conditions, imposed climatic conditions, the use of thinner pavements with a decreased structural capacity and thus shorter design lives, or a combination of these factors.
