Increasingly, travelers are turning to shared mobility and enabling technologies (i.e., smartphone apps) to meet their mobility needs. A consequence of the ever-growing and ever-evolving landscape of shared mobility is the lack of standardized terms and definitions. The shared and digital mobility industry is challenged with discrepancies in use and definition of terms, which often create ambiguity and confusion for policymakers, regulatory agencies, and the broader public. In recognition of this challenge, the SAE Shared and Digital Mobility Committee embarked on the task of developing J3163™ – Taxonomy and Definitions for Terms Related to Shared Mobility and Enabling Technologies. This white paper provides an overview of the rationale, scope, key discussions held in the development of J3163TM, as well as guidance on how to use J3163TM.

To date, the universal metric for road safety has been historical crash data, specifically, crash frequency and severity, which are direct measures of safety. However, there are well-recognized shortcomings of the crash-based approach; its greatest drawback being that it is reactive and requires long observational periods. Surrogate measures of safety, which encompass measures of safety that do not rely on crash data, have been proposed as a proactive approach to road safety analysis. This white paper provides an overview of the concept and evolution of surrogate measures of safety, as well as the emerging and future methods and measures. This is followed by the identification of the standards needs in this discipline as well as the scope of SAE’s Surrogate Measures of Safety Committee.

“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Fuel efficiency, or simply put, how to get more mileage out of the same amount of fuel has become one of the main goals to be achieved by new automotive technologies in the future, thanks in part to new government regulations. In the episode “Fuel Efficiency: Racing toward CAFE 2025” (21:24) AVL engineers show simulation and testing being used to design more fuel efficient vehicles, including the equipment that actually analyzes fuel economy.

The rapid pace of recent progress in vehicle electrification technologies points to a bright future for electric-drive vehicles, but uncertainty regarding future technical trajectories and uncertainty in consumer response make possible a multitude of electric-drive vehicle futures. This presentation will examine a range of these possible electric-drive futures as a function of different technology and pricing scenarios. An exploration of initial conditions, market uptake, and resulting social benefits will show how HEV and PEV technology enable the attainment of stringent vehicle efficiency goals and unlock potential for lower-carbon futures. Presenter Jacob Ward, Department Of Energy

The pace of replacement of petroleum-based fuels as the primary fuel supply for transportation may still be a point of debate. However, the need to find a viable replacement fuel or group of fuels is no longer a major point of debate. The panel will outline what has changed on the journey during the past few years and what the future holds. Viewpoints from government, the military, fuel suppliers and academia will be presented.

In 1990 in the USA, Section 206 of the Clean Air Act ushered in a new era in passenger car and light truck service and maintenance. Ensuing requirements led to introduction of sophisticated vehicle on-board diagnostic systems. These systems demand the increasing sophistication of service providers. The amount of service information has expanded exponentially. The sophistication of the tools needed to diagnose and repair vehicles has become increasingly complex. To meet the needs of today's service professionals, new systems had to be developed. The convergence of regulations, vehicle complexity, tool capabilities and the growing volume of service information required the vehicle producers and service communities to implement more efficient information delivery systems.

This collection chronicles the development of America's favorite sports car by the designers and engineers who made it happen. These 30 papers cover more than 50 years and six generations of the engineering, styling, and research and development of the Chevrolet Corvette. Twenty-two papers focus on the first five generations, with the last eight papers detailing the new sixth-generation Corvette. Material collected in this volume truly has unprecedented historical value. A 1954 paper by Maurice Olley presents a technical description of the first production Corvette. The book's preface includes insight from Zora Arkus-Duntov into the reasons behind the Corvette's development. Other highlights include comments from Corvette's chief engineer, a press release created by General Motors on its fiftieth anniversary, and a timeline with photos documenting the Corvette's evolution.

A key topic of many technical discussions has been the development of alternative fuels to power the compression ignition engine. Reasons for this include the desire to reduce the dependency on petroleum-based fuel and, at the same time, to reduce the particulate matter (PM) and NOx emissions. Also, there has been interest generated in the diesel engine because of the reduction in greenhouse gases that has been proposed during the 2008-2012 time frame in Europe and the regulations that affect diesel engines in the United States.

This report reviews concepts behind fuel cell technology, describes the improvements and vehicles that have been developed since 2001 as the technology has been refined, and examines the issue of what fuel should be used and the necessary refueling infrastructure. Chapters include: The Fuel Cell Vehicles The Race Is On Refueling Infrastructure The Future and more

This comprehensive report closely examines automakers' multibillion-dollar development of fuel cell technology and its potential to revolutionize the automotive industry. With the likelihood that fuel cells will be used in mass-produced vehicles as early as 2003 - nearly a decade earlier than previous estimates - the fuel cell powered vehicle is expected to make up about 7% of the total market share by 2011. This report is the most current and complete source of information on this innovative technology.
