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.

This Phase II Truck Platooning follow-on project described had two purposes: (1) hold two stakeholder workshops including a broad range of stakeholders (e.g., trucking fleet operators and managers, State and local government agency representatives, transportation planners, transportation policy advisors, law enforcement, and other interested parties) to disseminate the Phase I project information and collect feedback regarding motivations for adopting platooning technology, barriers to adopting platooning, and questions about the technology and (2) perform preliminary planning for a potential New York State platooning demonstration.The key identified needs were (1) inter-fleet platooning is needed to enable widespread NYS trucking fleet adoption, (2) business case—potential cost reductions and business models need to be quantified and proven before fleets will commit to platooning; including comparison of tandem trailers versus platooning, and (3) a system for identifying who is at fault when a crash occurs (driver or platooning system) is needed. The preliminary planning discussions for the truck platooning demonstration included: NYS Thruway Authority, NYS Department of Transportation, NYS Energy Research and Development Authority, NYS Police, NYS Department of Motor Vehicles/Governor’s Traffic Safety Committee, Peloton Technology, Daimler Trucks North America, and Energetics. The discussions confirmed continued interest in platooning because of its potential positive safety and energy efficiency benefits. The NYS Thruway is the preferred roadway for initial demonstration/limited validation testing efforts.

A cooperative truck platoon is a set of virtually linked trucks driving with a small intra-vehicle gap enabled by connected and automated vehicle technologies. One of the primary benefits of truck platooning is energy savings due to the reduction of aerodynamic drag on the platooned vehicles. The focus of this paper is on scheduling travel itineraries of a given set of trucks to maximize platooning opportunities and the corresponding energy savings. By constructing a time-expanded network, we formulate the problem as a minimum concave-cost network flow problem, and devise a number of solution methodologies to find the optimal or high-quality solutions. The solution methodologies include an outer approximation algorithm for solving a mixed-integer convex minimization reformulation of the problem, a dynamic-programming-based heuristic scalable to large-scale instances, and a fast approximation algorithm with guaranteed performance for a restrictive version of the problem. All the proposed algorithms are examined and benchmarked on medium to large networks under various test scenarios. The numerical results demonstrate the efficiency of the proposed methods and their applicability in real-world settings.

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).
