Selection of Strategic Projects
Strategic projects are large scale, complex, and require significant investments and resources. These projects aim at gaining long-term social and economic benefits. Therefore, organizations focusing on strategic projects should use a consistent approach that suits their strategy, capability, and long-term expectations.

SAVs Mobility Services and PT
Autonomous vehicles (AVs) represent the core technology that will revolutionize urban mobility in the future. AVs are considered upgraded versions of conventional vehicles that have high levels of automation to assist or replace human drivers. Shared autonomous vehicles (SAVs) is AVs used for the purpose of providing vehicle sharing services. When attempts are made to adopt AVs into shared and demand-responsive services, public transportation (PT) systems are affected, thereby creating changes in mode share. This could potentially create a difficult dilemma for many European and Asian cities that heavily rely on their public transportation systems.

Rural Logistic Facilities
Transport has long been considered a concern for rural residents around the world. Rural express logistics, one of the transport topics, is associated with rural residents’ convenience as well as e-commerce development. As key nodes in the network, logistic centers need to be properly located to improve the delivery efficiency. In general, existing studies on rural logistics are mostly conducted qualitatively. Most studies focus on policy suggestions on the development of rural e-commerce, while geographic, economic, and population data are not exploited enough. Although some issues such as route design and rural e-commerce are getting attention, there are still very few studies on site selection of rural logistic centers. Much uncertainty still exists about balancing the coverage rates with the operational cost when evaluating the optimal locations for logistic centers in remote rural areas with low population density. Quantitative methods are urgently needed for solving the logistic center locating problem, especially in areas at the early stages of building a rural logistic network.

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.

Road Traffic Crashes
Road traffic crashes (RTCs) are a major problem for authorities and governments worldwide. They incur losses of property, human lives, and productivity. 20 to 50 million people are injured in RTCs every year. The involvement of teenage drivers and road users is alarmingly prevalent in RTCs since traffic injuries unduly impact the working-age group (15–44 years).

Road Safety Near a Landfill Assessment in Europe
In Europe, many governments are struggling with the ambitious target of zero road deaths by 2050. On the other hand, they are facing remediation of illegal waste dumps, subject to European infringement procedures and involving a lot of workers and heavy materials transportation. In Italy, a specific department was started in 2017 to carry out the remediation of 200 illegal landfills of urban/industrial solid waste. According to the Italian legislative framework on construction site management, risk assessment should also include risks for the external context caused by the working site.

Road Safety in Roadwork Zones
The number of zones where roadworks are carried out is continuously increasing, so the number of risky situations in which drivers can find themselves is also increasing. Roadwork zones represent high-risk conditions in traffic, both for road users and for construction workers. This paper presents and analyses data on road crashes and their consequences in roadwork zones, including the analysis of four typical roadwork situations that could pose a risk for traffic participants.

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.

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.

Reversible Hydrogen Storage
In the field of energy storage, recently investigated nanocomposites show promise in terms of high hydrogen uptake and release with enhancement in the reaction kinetics. Among several, carbonaceous nanovariants like carbon nanotubes (CNTs), fullerenes, and graphitic nanofibers reveal reversible hydrogen sorption characteristics at 77 K, due to their van der Waals interaction. The spillover mechanism combining Pd nanoparticles on the host metal-organic framework (MOF) show at room temperature uptake of hydrogen. Metal or complex hydrides either in the nanocomposite form and its subset, nanocatalyst dispersed alloy phases illustrate the concept of nanoengineering and nanoconfinement of particles with tailor-made properties for reversible hydrogen storage. Another class of materials comprising polymeric nanostructures such as conducting polyaniline and their functionalized nanocomposites are versatile hydrogen storage materials because of their unique size, high specific surface-area, pore-volume, and bulk properties. The salient features of nanocomposite materials for reversible hydrogen storage are reviewed and discussed.
