Multimodal Freight Transportation Research Roadmap

BACKGROUND
As outlined in the U.S. DOT’s 30-year plan, Beyond Traffic, the nation’s ability to compete in global markets and to meet the needs and expectations of consumers and industry depends on a robust multimodal freight transportation system and agile and efficient supply chains. Rural communities, cities, and metropolitan areas rely on supply chains, and the supporting freight transportation systems, to send and receive vast amount of supplies needed by local economies. For example, freight-intensive-sectors (e.g., manufacturing, wholesale, retail, food, accommodation) – for which the production and/or consumption of supplies are an essential part of their business – represent 45% of the establishments and 50% of the employment in the United States.  Inefficient supply chains will have a negative effect on all of them, hampering economic activity. Furthermore, the freight system is under serious strain, with roads, railways, and airports becoming increasingly congested and increasingly aging.
Market and technological trends are impacting freight activity patterns in numerous ways, both globally and locally.  International trade is increasing, global manufacturing centers are shifting, and trade routes are changing.  Firms are driving down logistics costs through just-in-time shipping.  Online shopping is increasing demand for home delivery of consumer products, especially in dense urban environments.  Retailers, faced with new mobile computing consumer buying behavior, are experimenting with a wide range of new transportation options for last mile delivery. Intermodal freight shipped in containers via ships, trains, and trucks is continuing to grow. Surging domestic energy production is straining infrastructure in oil production regions.  In the next 30 years, changes in freight demand, shipping, manufacturing, logistics, technology, and energy production are poised to transform the economics of transportation yet again. By 2045, freight volume will increase 45% from current levels.
The increasing congestion in metropolitan areas is a major threat to the U.S. economy. About 80% of the freight transported in the U.S. has its origin or destination at one of the top 100 metropolitan areas, reflecting that the bulk of manufacturing is produced in metropolitan areas, and in turn, increases congestion and emissions in these areas. Taking into account the surge in Internet orders in the last several years, it is almost certain that deliveries to households now generate more freight trips than deliveries to commercial establishments.
At the same time, a host of new technologies and operational practices are transforming freight transportation systems and supply chains. Smart City technologies, truck platooning, autonomous trucks, drones, 3D printing, delivery crowdsourcing, and others are already making their mark. As an example, 3D printing may lead to decentralization of manufacturing and to the development of on-demand manufacturing, resulting in unforeseen demands on road infrastructure because of the growth in small truck freight trip generation.
There is a need to better understand the current and anticipated future freight trends to provide transportation agencies with the information they need to develop strategic plans. More specifically, research is needed to gain insight into how market and technological trends could impact transportation systems, safety, and the environment. Conducting research, with the collaboration of other stakeholders, that identifies, designs, pilot tests, and leads to the adoption of effective public sector freight initiatives, will help transportation agencies achieve their goals.
OBJECTIVE
The objective of this project is to develop a dynamic 5- to 10-year multimodal freight research roadmap. The roadmap should emphasize problem statements with a scope and budget appropriate for NCHRP, but can include problem statements that are more suitable for other public, private, or academic research institutions or programs.  The research roadmap should clearly define a portfolio of initiatives that will advance the knowledge and capabilities of transportation decision makers.  The research roadmap should include, but not be limited to: (1) end-to-end emphasis (i.e., consider the research needs of all modes and stages of freight activity, from gateways, to corridors, to local deliveries); (2) identifying and assessing the impacts of social, technological, economic, environmental, and political trends on freight transportation systems and policies; (3) enhancing public sector decision-making capabilities (i.e., the research roadmap should lead to the development of new tools or methods and ways to gather necessary data for public agencies to make decisions that improve freight system performance); (4) expanding and deepening public sector knowledge (i.e., the research roadmap should contain projects that enhance the public sector’s understanding of the behavior of the agents involved in freight, and the best ways to influence them to improve freight system performance); and (5) addressing institutional issues (i.e., analyzing current and potential barriers to preventing improved freight transportation systems that could increase economic efficiency and productivity, foster sustainability, enhance livability, quality of life, and environmental justice).
The research roadmap should include: (1) a prioritized portfolio of problem statements, most of which should address the research gaps in a format and at a level of detail suitable for submission to NCHRP; (2) a detailed description and justification of how this portfolio addresses the five objective criteria; (3) an assessment of key gaps and needs that could be addressed through research and how this portfolio addresses these gaps; and (4) a dynamic communications concept (including format, platform, frequency, distribution channels, budget, and editorial and technical content) that could be widely distributed to keep practitioners informed of emerging issues affecting freight transportation.

Research Roadmap — Transformational Technologies (other than CV/AV)

BACKGROUND
Transformational, or “disruptive” technologies, are those that can be expected to completely displace the status quo, forever changing the way we live and work. Common examples include the internet, the personal computer, email, and the smart phone. The development of the internal combustion engine is an example of a disruptive technology in the transportation sector.
More current examples of transformational technologies in transportation include connected and automated vehicles, bicycle sharing in urban centers, car sharing (e.g. Car2Go and Zipcar), on-demand shared ride services (such as Uber and Lyft), hybrid and other alternative-fueled vehicles, drones, e-retailing, and 3D printing. All of these are facilitated and further complicated by the “Internet of Things” – where systems are connected through embedded sensors and transmitters. The acquisition of real-time data on the infrastructure, vehicles, drivers, and goods will provide unprecedented opportunities to monitor the performance of our transportation systems.
Each of these technologies is the subject of a good deal of research, but collectively they will change the nature and role of the future Department of Transportation. Transformational technologies will impact the way we plan, design, construct, operate, and maintain our transportation systems. DOTs must prepare for an uncertain future and build a workforce with considerably different skill sets. The NCHRP has developed a research roadmap for connected and automated vehicles (through NCHRP Project 20-24(98)) and is carrying out a program of research to address identified needs. However, there are other transformational technologies that need to be studied and better understood.
There is a need to understand how transportation agencies will be impacted by transformational technologies in order to provide them with the information they need to develop strategic goals and objectives by analyzing the current issues and state of knowledge, identifying gaps and needs, and outlining a program of research to address those gaps and needs.
OBJECTIVE
The objective of this research is to develop a research roadmap on transformational technologies and their impacts on state and local departments of transportation. A research roadmap is a type of strategic plan that outlines the key issues in an area, identifies research gaps that constrain effective decision-making, and outlines specific research projects needed to address these gaps.

RESEARCH PLAN

The initial phase of this work is to support TRB’s Partners in Research Symposium: Transformational Technologies in Transportation through NCHRP Project 20-113A (link below). Upon completion, the panel will determine how best to use the remaining resources.

Strategic Issues Facing Transportation, Volume 7: Preservation, Maintenance, and Renewal of Highway Infrastructure

The transportation industry faces a wide range of plausible future drivers and scenarios that could affect standard practices over the next 30 to 50 years. Because the range of plausible futures over such a long-term period is very broad, making a focused prediction of the implications for highway infrastructure preservation, maintenance, and renewal (PMR) is quite challenging.

The TRB National Cooperative Highway Research Program’s NCHRP Report 750: Strategic Issues Facing Transportation, Volume 7: Preservation, Maintenance, and Renewal of Highway Infrastructure focuses on the issues affecting the PMR of highway infrastructure. The study places emphasis on preparing for plausible future scenarios and develops a pathway to guide transportation agencies in advancing the implementation of emerging PMR practices through a process involving awareness, advocacy, assessment, adoption, and action planning.

The appendices to Parts A and B of this report are available as part of NCHRP Web-Only Document 272: Existing and Emerging Highway Infrastructure Preservation, Maintenance, and Renewal Definitions, Practices, and Scenarios.

In addition, there are two guides included within the report that help with the understanding, identification, application, and implementation of emerging PMR practices. They are also available as standalone guides:

• Practitioner’s Guide to Emerging Highway Preservation, Maintenance, and Renewal Practices
• Leadership’s Guide to Emerging Highway Preservation, Maintenance, and Renewal Practices
