Passenger Cars Driven on Hilly Roads in Austria
Previous studies of road or railway infrastructures have shown that traffic emissions outweigh the environmental impacts of the product stage and construction stage over the entire life cycle. Traffic usage is therefore the main emitter over the life cycle (A1–C4). Due to the small number of sustainability assessment systems, the question of how to consider traffic emissions in detail in an integral life cycle assessment has arisen.

Navigation and Communication of UAS Operating in BVLOS
Unmanned Aerial Systems (UAS) have rapidly gained attraction in recent years as a promising solution to revolutionize numerous applications and meet the growing demand for efficient and timely delivery services due to their highly automated operation framework. Beyond Visual Line of Sight (BVLOS) operations, in particular, offer new means of delivering added-value services via a wide range of applications.

Infrastructure and Road Safety of Electric Vehicles
The electrification of road transport is developing dynamically around the world. Many automotive companies are introducing electric vehicles to the market, and their popularity is constantly growing. The increasing popularity of electric vehicles is caused by individual countries’ governments encouraging people to switch to electric vehicles and their lower operating costs.

Quantifying the Complexity of the Autonomous Vehicles Environment
One of the challenges that autonomous vehicles (AVs) face is the large amount of data inundating the onboard computer from its sensors, which is beyond the real-time processing capabilities of current AV models. The onboard computer equipped by the AVs, which is required to operate in real- time, has the onus of perceiving the environment surrounding the AV, processing the incoming information, and making the most apt decisions to ensure the safe operations of the ego vehicle.

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.

Prediction of Bike Sharing Demand and Design
As a consequence of the persistent trend towards urbanization, cities suffer from negative externalities (traffic congestion, air pollution, noise, etc.) caused by the increase in urban mobility. Since motorized individual transport comprises a sizable proportion of those negative effects, policymakers consider the promotion of active mobility (i.e., walking and cycling) as a way to address the key challenges of growing urban transport. In this regard, bike sharing systems have gained popularity, as they provide a sustainable and affordable alternative to motorized vehicles. Therefore, these systems are increasingly implemented in cities around the world.

Ridesharing Impacts
Ridesharing is part of the innovative shared transport regime which aims to maximize the utilization of mobility resources. Gaining knowledge of ridesharing’s impacts and how to assess them may significantly improve such services and thus contribute to their adoption among broader groups of travelers and to travel behavior change.

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.

Transport Environmental Effects of Urban Road Network
As both developing and developed countries continue to urbanize, rapid urban growth is anticipated, particularly in low- and middle-income countries. This will inevitably lead to enhancements in economic development, as well as the expansion of production, population, employment, travel demand, and freight transport demand in urban road networks. Transport can potentially lead to multiple social and environmental effects, such as difficulty with access, social severance, pedestrian accident risk, higher noise levels, greater air pollution, global warming, climate change, and other adverse consequences.

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.
