SESAR: The Past, Present, and Future of European Air Traffic Management Research Perspective
Tatjana Bolić, Paul Ravenhill
Engineering 2021, Volume 7, Issue 4, Pages 448-451 doi: 10.1016/j.eng.2020.08.023
The Single European Sky ATM Research (SESAR) project is the technological pillar of the European Commission’s Single European Sky Initiative to modernize air traffic management (ATM). Here, we describe the process of establishing SESAR and the main parts of the project: the research and development (R&D) part, which is led by the SESAR Joint Undertaking; the deployment part, which is managed by the SESAR Deployment Manager; and the European ATM Master Plan, which collects and lays out both the R&D and deployment needs. The latest European ATM Master Plan was adopted just prior to the current pandemic. The huge loss in air traffic due to the pandemic, and the speed of the recovery of the aviation industry will require reprioritization, but the main elements that have been established—particularly those in support of the environment—remain valid.

Strategic Study of CAE 2021, Volume 23, Issue 3, Pages 163-172 doi: 10.15302/J-SSCAE-2021.03.020
Developing a localized virtual urban transportation system (VUTS) and a decision support mode for transportation development is significant for solving the increasingly severe urban traffic problems caused by rapid urbanization and for overcoming the current bottlenecks that restrain the intelligent transportation system development. Based on the advanced information technologies such as big data and Internet technologies, this study establishes a VUTS that is composed of four parts: basic databases, analysis models, software platforms, and alternative plans; the theoretic framework, systematic functions, and technical system of the VUTS are analyzed. Furthermore, a decision support mode for transportation development is proposed; it covers the application scenarios including urban land development, traffic facilities construction, traffic operation control, public transport operation, and traffic policy making. Subsequently, we built the VUTS of Chongqing and provided plans for the municipal government regarding its decision on shifting peaks for residents and vehicles during the outbreak of the COVID-19 epidemic. The case results suggest that the decision support mode based on VUTS is effective in the demonstration of traffic plans. Therefore, we suggest that China attach importance to the VUIS and its application in urban traffic planning and management and incorporate new information technologies to optimize the application effects.

Considering the high-quality development of the energy sector in China, the integration of energy and transport sectors can facilitate the low-carbon, high-efficiency, and intensive development of both sectors and contribute to carbon peaking and carbon neutralization. This study reviewed the development status and trend of the energy system for land transport and proposed a novel system architecture, which consists of power, physical, and application levels. Three integrated scenarios—interconnected power grid, electrified transportation, and energy-transport integrated network—are analyzed from the energy-dominated, transport-dominated, and energy-transport integrated perspectives. Moreover, a novel development strategy for land transport energy system is proposed based on the potential evaluation of natural resources available for transport energy systems of both highways and high-speed railways. A development strategy consists of three structures, three scenarios, and three driving forces is proposed to guide the construction of a low-carbon and efficient transport infrastructure system. The innovation directions for the transport energy system include key equipment research and development, construction and maintenance of the integrated system, and formation of technical specifications and standards. Therefore, it is essential to promote a modern transport energy system that is dominated by renewable energies and supported by electric power. Furthermore, a new transport power system that integrates renewable energy generation, zero-carbon fuel, and electric drive should be established, and a transport‒energy integrated infrastructure should be planned and constructed.

Transportation and energy are crucial for social development and civilization evolution. The energization of transportation infrastructure assets and clean transformation of transportation energies are effective decarbonization strategies for solving severe challenges such as resource shortage, climate change, and environmental pollution. This study first reviews the integration history of road transportation and energy, and investigates the demand for and trends of the integration from the perspectives of national energy security, clean transformation of energy supply, energization potential of transportation infrastructure assets, and intelligentization of the transportation system. The pathway for promoting the integrated development of road transportation and the energy sector is proposed based on assessing the wind and solar resources and the self-consistent supply capacity of energies within the road transportation system. Moreover, a roadmap for integrating road transportation and renewable energies is proposed considering the carbon peak and carbon neutralization targets. Finally, suggestions are proposed from two aspects. In terms of technology development, we suggest that China should enhance technology research and development, improve the industry chain, and promote technology innovation and integration. Additionally, it should provide policies for improving top-level design and strategic planning, exploiting new market modes, and strengthening international cooperation.

Urban air mobility (UAM) is an emerging concept proposed in recent years that uses electric vertical take-off and landing vehicles (eVTOLs). UAM is expected to offer an alternative way of transporting passengers and goods in urban areas with significantly improved mobility by making use of low-altitude airspace. In addition to other essential elements, ground infrastructure of vertiports is needed to transition UAM from concept to operation. This study examines the network design of UAM on-demand service, with a particular focus on the use of integer programming and a solution algorithm to determine the optimal locations of vertiports, user allocation to vertiports, and vertiport access- and egress-mode choices while considering the interactions between vertiport locations and potential UAM travel demand. A case study based on simulated disaggregate travel demand data of the Tampa Bay area in Florida, USA was conducted to demonstrate the effectiveness of the proposed model. Candidate vertiport locations were obtained by analyzing a three-dimensional (3D) geographic information system (GIS) map developed from lidar data of Florida and physical and regulation constraints of eVTOL operations at vertiports. Optimal locations of vertiports were determined to achieve the minimal total generalized cost; however, the modeling structure allows each user to select a better mode between ground transportation and UAM in terms of generalized cost. The outcomes of the case study reveal that although the percentage of trips that switched from ground mode to multimodal UAM was small, users choosing the UAM service benefited from significant time saving. In addition, the impact of different parameter settings on the demand for UAM service was explored from the supply side, and different pricing strategies were tested that might influence potential demand and revenue generation for UAM operators. The combined effects of the number of vertiports and pricing strategies were also analyzed. The findings from this study offer in-depth planning and managerial insights for municipal decision-makers and UAM operators. The conclusion of this paper discusses caveats to the study, ongoing efforts by the authors, and future directions in UAM research.

Strategic Study of CAE 2018, Volume 20, Issue 2, Pages 106-110 doi: 10.15302/J-SSCAE-2018.02.016
The development of transportation engineering is performed with a focus on the coupling between human, vehicles, and roads to improve the level of efficiency, safety, and environmental friendliness. Technologies associated with the cooperative vehicle infrastructure system (CVIS), which is based on the concepts of intelligent vehicles and V2V and V2I communication, will cause the transportation system configuration to gradually change from human-vehicle-road coordination to vehicle-infrastructure cooperation, thereby greatly improving traffic efficiency and safety. Under the CVIS environment, conventional human factors affecting traffic have less influence, and the coupling of human-vehicle-road is enhanced; thus, the systems can be controlled and evaluated effectively, and the randomness in traffic systems can be reduced. The processes of perception, decision-making, and control are performed by robots instead of humans, and this could lead to numerous changes and challenges to the theory of transportation. This paper discusses the influence of CVIS on transportation engineering, and the associated scientific issues.
