Book Description
Freight travel accounts for a major share of the energy consumed in the transportation sector in any country, and the United States is no exception. Understanding and modeling freight movement is critical, particularly in the context of capturing the impact of emerging technologies on freight travel and its externalities. The domain of freight modeling and forecasting is gaining pace in the recent years, but advancement in comprehensive freight performance metrics is still lagging. Conventional freight performance metrics such as truck-miles, ton-miles, or value-miles are unidimensional and aggregated in nature, making them unsuitable to accurately capture the impact of emerging transportation trends on the performance of freight systems. Addressing this research need, this paper presents the 'Freight Mobility Energy Productivity' metric to quantify freight performance of current as well as future freight systems, accounting for various costs associated with freight transport. The proposed metric was implemented using data from the Freight Analysis Framework along with other published sources, which shows intuitive results in quantifying freight performance. Further, a scenario analysis exercise was conducted to test the capability of the metric in tracking improvements in system-level freight efficiency as a result of vehicle powertrain technology improvement. Results of the scenario analysis reinforce confidence that the proposed metric can be used as a decision support tool in assessing the efficiency of existing as well as future freight trends and technologies.

Book Description
For nearly a century, the automobile has been the primary mode of personal transportation in American life. This remains true today as millions of people rely heavily on cars to connect suburbs with cities or to travel long distances - often out of routine or convenience. However, advances in technology are fueling an era of transportation transformation, with the potential to transform a system that has remained virtually unchanged for decades. The challenges of interconnecting our cities and creating a cross-continental transportation system for military purposes spawned the interstate highway system, generating the age of the automobile. In this century, congestion and mobility challenges of rising urban populations are spawning ever-evolving mobility and communications technologies to connect people to goods, services, and employment within a metropolitan and national context - all of which define a high quality of life. Aspiring smart cities are wrestling with questions such as: How does mobility impact a person's quality of life? Would people make different travel choices if they were presented with better information about their mobility options? Would businesses make different location decisions if they could assess the quality of mobility in that area? The ability to quantify the quality of mobility at a given location is the first step toward answering these questions. In response, an interdisciplinary team at the National Renewable Energy Laboratory (NREL) has developed the Mobility-Energy Productivity (MEP) metric. The MEP metric provides an avenue to not only measure the quality of mobility at a specific location in its current configuration, but also to test how various technological advances (e.g., connected and automated vehicles, plug-in electric vehicles, shared mobility) and infrastructure investments (e.g., building an additional highway lane, constructing a new shopping mall, implementing a transit-oriented development) impact the mobility of that location over time.

Book Description
This project addresses the impact of emerging technologies on inter-city freight energy demand, shipping time, and cost. Technologies addressed include electrified long-haul trucks, connectivity and efficient operations, and platooning. The research questions are addressed using national level analysis, a multi-modal inter-city freight energy model, and development of a Freight Mobility Energy Productivity (F-MEP) metric. This project improves on national level analysis and modeling completed in prior fiscal years by disaggregating freight flows both geographically and temporally and incorporating both energy and cost in the modeling framework. The inter-city freight energy model uses a bi-level optimization approach to minimize total network cost (lower level) and energy (upper level). Two new F-MEP frameworks are presented, one for intra-city freight mobility and one for inter-city freight mobility.

"NCFRP Report 21: Handbook on Applying Environmental Benchmarking in Freight Transportation identifies and evaluates approaches that can be used by public and private entities to estimate, monitor, and reduce freight emissions and impacts across the supply chain by examining how benchmarking can be used as a management tool in the freight and logistics industry to promote environmental performance. The handbook provides a step-by-step overview of the benchmarking process and describes a framework for applying this process to freight carriers, shippers, and freight hubs"--Foreword.

Book Description
Master's Thesis from the year 2016 in the subject Business economics - Supply, Production, Logistics, grade: 1, Vienna University of Economics and Business (Informationsverarbeitung & Prozessmanagement), language: English, abstract: Changing economic conditions and increasing competition forced many companies to extend their supply, production and distribution networks towards global approaches. This led to an increase in the importance of freight transport. In consequence, freight carriers are currently required to provide either cost or time efficient solutions to a wide range of industries. In order to select appropriate modes of transport or suitable carriers, enterprises must consider their performance beforehand. Moreover, carriers must be precisely aware of their own performance at any time. Consequently, performance measurement and the definition of suitable performance metrics plays an essential role in freight transport. In practice, companies have to face an extensive variety of indicators that can be used to assess performance in freight transport. Studies prove that there is lack of consistency in the usage of metrics. At the same time, researchers have to cope with wide range of available literature that discusses performance evaluation in freight transportation which is, though, often limited to specific areas of application. In this thesis a structured literature review (SLR) is carried out which has the objective to systematically find out how companies measure performance in intermodal, road, rail, air, and maritime freight transport. The conceptual findings of this SLR provide a list of 1742 metrics from the literature that can either be applied for one or several modes of freight transport. In addition, 47 different ways how KPIs can be classified are identified. The SLR proves that operational performance indicators mainly regard time, distance and available equipment. Strategic metrics focus on costs levels, the change of costs over time, ra

Book Description
The purpose of this report is to identify potential improvements in terms of more effective safety and environmental regulation for trucks, backed by better systems of enforcement, and to identify opportunities for greater efficiency and higher productivity. The report is based on a review of literature, consultation among stakeholders, and research and analysis from working group members. It also presents the results of a comprehensive benchmarking study of 39 truck configurations in operation around the world – from typical workhorse vehicles to very high capacity vehicles – and assesses their performance in terms of dynamic stability, productivity and impact on the infrastructure.
