Advance Local Mobility Through Energy Efficient Mobility Systems Technologies
3/25/2024
Everyone deserves reliable, affordable, and safe transportation to connect people to jobs, healthcare, education, and recreation. Our transportation systems are interconnected, multimodal networks working together to move people and goods. These systems are dynamic and are being reshaped by factors such as population trends, new technologies, shifting labor models, economic forces, and changing climate. Energy efficient mobility systems (EEMS) technologies can help transportation planners ensure changes in our transportation systems are equitable and sustainable by improving energy efficiency, travel time, and affordability, as well as overall access to mobility. Transportation planners and decision makers can use the following EEMS tools and strategies to advance local mobility.

Fort Erie On-Demand Transit Case Study
1/1/2023
Rural and smaller-sized communities in North America face unique mobility challenges due to their low population density, lower public transit spending per capita compared to major cities, and a high reliance on private vehicles. In recent years, communities such as Fort Erie, Ontario, have restructured or advanced their public transit systems using on-demand services. This report documents both the previous system and the new system in terms of routes, ridership, costs, fuel, and other notable system parameters. This work is part of an ongoing series of case studies on providing small communities with on-demand, right-sized vehicle service coupled with a smartphone application.

The Automated Mobility District Implementation Catalog, 2nd Edition
8/1/2022
The first edition of the Automated Mobility District Implementation Catalog was published by the National Renewable Energy Laboratory (NREL) to document insights gained from monitoring 10 early deployment sites of automated vehicle (AV) technology. Since the publishing of the first edition, NREL has tracked the effects the 2020 pandemic and the progress of the demonstration pilot projects beyond the initial deployment phase has generated important new information. The objective of this second edition is to provide an update to the status of the 10 early deployment sites to assess common trends of technology development and deployment. Drawing from that new insight, this report documents the natural maturing of the AV technology industry. This second edition reports on the framework of “cardinal principles” that the research team has defined for the safest and most efficient application of AV technology in managed fleet deployment within automated mobility districts of the future.

Measuring Fundamental Improvements in Sustainable Urban Mobility: The Mobility-Energy Productivity Metric
7/9/2019
Recent technological advancements in mobility are creating many options for connecting citizens with employment, goods, and services, particularly in urban areas where modes such as bike and car shares, electric scooters, ridesourcing, and ridesharing are proliferating at a rapid pace. Analysis and tools for overall transportation planning are dominated by urban regional travel demand models whose roots in highway operations poorly reflect the system dynamics in denser areas where parking costs, convenience, and availability - not to mention sustainability concerns and quality of life - are driving people to an ever-greater spectrum of mobility services. In this paper, we present a new paradigm for evaluating mobility options within an urban area. First developed for the U.S. Department of Energy's Energy Efficient Mobility System research program, this metric is termed the Mobility-Energy Productivity (MEP) metric. At its heart, the MEP metric measures accessibility and appropriately weights it with travel time, cost, and energy of modes that provide access to opportunities in any given location. The proposed metric is versatile in that it can be computed from readily available data sources or derived from outputs of regional travel demand models. End times associated with parking, curb access, cost, and reliability and frequency of service need to be carefully considered to obtain an appropriate and accurate perspective when computing the metric based on outputs from regional travel demand models. Ultimately, the MEP metric can be used to reflect the impacts of new mobility technologies (transportation network companies, electric scooters), business models (car shares and bike shares), and land-use practices (such as transit-oriented development) on sustainable urban mobility. This paper lays out the need, requirements, and framework for this new metric, and offers it, in collaboration with the American Society for Civil Engineers (ASCE), as a foundational metric for Smart City assessment.
