Book Description
This open access book presents research and evaluation results of the Austrian flagship project “Connecting Austria,” illustrating the wide range of research needs and questions that arise when semi-automated truck platooning is deployed in Austria. The work presented is introduced in the context of work in similar research areas around the world. This interdisciplinary research effort considers aspects of engineering, road-vehicle and infrastructure technologies, traffic management and optimization, traffic safety, and psychology, as well as potential economic effects. The book’s broad perspective means that readers interested in current and state-of-the-art methods and techniques for the realization of semi-automated driving and with either an engineering background or with a less technical background gain a comprehensive picture of this important subject. The contributors address many questions such as: Which maneuvers does a platoon typically have to carry out, and how? How can platoons be integrated seamlessly in the traffic flow without becoming an obstacle to individual road users? What trade-offs between system information (sensors, communication effort, etc.) and efficiency are realistic? How can intersections be passed by a platoon in an intelligent fashion? Consideration of diverse disciplines and highlighting their meaning for semi-automated truck platooning, together with the highlighting of necessary research and evaluation patterns to address such a broad task scientifically, makes Energy-Efficient and Semi-automated Truck Platooning a unique contribution with methods that can be extended and adapted beyond the geographical area of the research reported.

Book Description
This report assesses how FHWA's investment in truck-platooning research affected truck platooning knowledge, the availability and quality of data, and the deployment of truck platooning technology. The research projects reviewed in this report are the "Partial Automation for Truck Platooning" (PATP) and "Driver-Assistive Truck Platooning" (DATP). The focus of the PATP and DATP projects was to decrease the costs of freight travel by improving fuel efficiency and highway mobility and allowing long-haul trucks to travel together as efficiently as possible. Although it was difficult to measure the effects of specific FHWA activities, the Research and Technology Evaluation project team found the research output from PATP and DATP addressed previously identified research gaps, influenced stakeholders' overall technology awareness and knowledge of truck-platooning technology, and led the way for follow-on research. All interviewees agreed the benefits outweighed the costs and all but one—who was unsure—had a positive impression of qualitative return on investment. Having project partners commit to cost sharing showed potential payback for project partners, while research output from the PATP and DATP projects showed that truck platooning was a viable option to help increase fuel efficiency among two- and three-truck platoons.

Book Description
The transportation industry is going through many changes as populations grow and new technologies pave the way to the future of transportation. One of the emerging technologies in transportation is Connected and Autonomous Vehicles (CAVs), promising many improvements by using advanced technologies. There is, however, so much research and development required to reach full deployment of CAVs and fill the transition from human driven vehicles to fully automated vehicles. As a result of positive environmental and economic impacts of automated truck platoons on the transportation industry, it is expected that they will be among the first applications of CAVs deployment. However, it is also important to evaluate their impacts on traffic flow in order to have a comprehensive deployment plan. Previous studies have shown mixed effects of truck platooning on traffic flow; however, many researchers did not consider the impacts of on- and off-ramps as it is the case in many urban freeways. The main objective of this thesis is to examine whether automated truck platoons would have a positive impact on traffic flow in terms of the appropriate performance measures based on different characteristics of platooning. To do so, a comprehensive literature review was conducted. Additionally, using VISSIM microsimulation software, a case study of a 5.5 mile corridor of the I-880 freeway having 8 on-ramps and 5 off-ramps during AM peak hour was conducted to evaluate the impacts of automated truck platoons on traffic flow. According to the results of the case study, automated truck platoons negatively impact traffic flow in terms of average speed, total network delay, and total time spent in the network based on different factors of platooning, including gap, market penetration rate, and platoon size. Statistical tests indicated that only market penetration rates of more than 30% have significant impacts on the performance measures compared to the base scenario. This negative impact could be as a consequence of high traffic volume (i.e., nearly 70% of capacity), high truck proportion, and closely spaced ramps (i.e., high ramp density).

Book Description
This book discusses the latest advances in research and development, design, operation and analysis of transportation systems and their complementary infrastructures. It reports on both theories and case studies on road and rail, aviation and maritime transportation. Further, it covers a wealth of topics, from accident analysis, vehicle intelligent control, and human-error and safety issues to next-generation transportation systems, model-based design methods, simulation and training techniques, and many more. A special emphasis is placed on smart technologies and automation in transport, and on the user-centered, ergonomic and sustainable design of transport systems. The book, which is based on the AHFE 2019 International Conference on Human Factors in Transportation, held on July 24-28, 2019, in Washington D.C., USA, mainly addresses the needs of transportation system designers, industrial designers, human–computer interaction researchers, civil and control engineers, as well as vehicle system engineers. Moreover, it represents a timely source of information for transportation policy-makers and social scientists whose work involves traffic safety, management, and sustainability issues in transport.
