Download or read book Unsettled Issues Regarding First and Last mile Transport written by Jody Emlyn Muelaner and published by SAE International. This book was released on 2021-10-15 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable first/last/only-mile (FLO-mile) transport is the key to sustainable travel. It could directly replace private car use for short urban journeys, which account for 1% of global greenhouse gas emissions. More importantly, it could enable public transport to be used for longer journeys, which account for 6% of emissions. Active travel, such as walking and cycling, has the lowest emissions and provides huge economic benefits that pay for the required infrastructure many times over. Unsettled Issues Regarding First- and Last-Mile Transport discusses the mass switch to more sustainable modes of transport and how to increase their perceived value to users. It also covers the prioritization of publicly owned cycles over rideshare options due to the latter’s higher lifecycle emissions, including manufacture, redistribution, and service operations and station construction.

Download or read book Unsettled Issues in Remote Operation for On road Driving Automation written by Sven Beiker and published by SAE International. This book was released on 2021-12-15 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-road vehicles equipped with driving automation features—where a human might not be needed for operation on-board—are entering the mainstream public space. However, questions like “How safe is safe enough?” and “What to do if the system fails?” persist. This is where remote operation comes in, which is an additional layer to the automated driving system where a human remotely assists the so-called “driverless” vehicle in certain situations. Such remote-operation solutions introduce additional challenges and potential risks as the entire vehicle-network-human now needs to work together safely, effectively, and practically. Unsettled Issues in Remote Operation for On-road Driving Automation highlights technical questions (e.g., network latency, bandwidth, cyber security) and human aspects (e.g., workload, attentiveness, situational awareness) of remote operation and introduces evolving solutions. The report also discusses standards development and regulations—both of which are needed to provide frameworks for the deployment of driving automation with remote operation.

Download or read book Unsettled Issues Concerning the Opportunities and Challenges of eVTOL Applications during a Global Pandemic written by Johnny Doo and published by SAE International. This book was released on 2020-10-30 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advancements of electric vertical takeoff and landing (eVTOL) aircraft have generated significant interest within and beyond the traditional aviation industry, and many new and novel applications have been identified and under development. The COVID-19 crisis has highlighted the challenges of managing a global pandemic response due to the difference in regional and local resources, culture, and political systems. Although there may not be a uniform crisis management strategy that the world can agree on, we can leverage a new generation of vertical flight vehicles to make a difference if (or when) such a global epidemic strikes again. One of the key challenges realized in the early stage of the COVID-19 outbreak is the ability to allocate and distribute limited and critical medical resources, including equipment, supplies, medical personnel, and first responders to the hot spots when and where they may be needed. The on-demand logistics capabilities could be enhanced by the availability of new-generation eVTOL aircraft and their forthcoming autonomous operation. The ability to land and takeoff at many unconventional locations makes eVTOL aircraft valuable assists for complementing and enhancing on-demand logistic needs. To make such operations truly productive is not easy; there are reassociated challenges that needed to be addressed to enable the benefit of such a system. In addition to having a large enough eVTOL fleet near a location that can be available for the pandemic responses, the support system and the ability to deploy and reposition the fleet dynamically with supporting infrastructures are also required. Based on the rapid development progress of eVTOL, it is envisioned that those challenges can be addressed soon. https://doi.org/10.4271/EPR2020022

This book was released on 2020-10-30 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: With billions of dollars of investment and events like DARPA’s Grand Challenges automated driving technology has been making its way toward commercialization. While the enabling technology for SAE Level 4 and 5 automated vehicles (AV) has not yet matured, specific restricted-use models such as “robo-taxis” and automated truck convoying show great promise. Now, cities are across the world are looking to AVs to solve their public transportation issues. With low speeds and fixed route, public transportation is an ideal application for AVs. From a business angle, AVs could leverage existing public transport models and infrastructure while providing superior quality of service for disadvantaged communities. Yet, dense urban environments—which would benefit from automated transportation the most—present unique challenges and public sector requirements. This SAE EDGE™ Research Report by Dr. Rahul Razdan examines the divergent applications and experiences of four urban cities as they engage with AV technology for their specific purposes: Jacksonville and Orlando, Florida; Tallinn; and Singapore.

Download or read book Unsettled Impacts of Integrating Automated Electric Vehicles into a Mobility as a Service Ecosystem and Effects on Traditional Transportation and Ownership written by Joachim Taiber and published by SAE International. This book was released on 2019-12-20 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current business model of the automotive industry is based on individual car ownership, yet new ridesharing companies such as Uber and Lyft are well capitalized to invest in large, commercially operated, on-demand mobility service vehicle fleets. Car manufacturers like Tesla want to incorporate personal car owners into part-time fleet operation by utilizing the company’s fleet service. These robotaxi fleets can be operated profitably when the technology works in a reliable manner and regulators allow driverless operation. Although Mobility-as-a-Service (MaaS) models of private and commercial vehicle fleets can complement public transportation models, they may contribute to lower public transportation ridership and thus higher subsidies per ride. This can lead to inefficiencies in the utilization of existing public transportation infrastructure. MaaS platforms can also cause a reduced reliance on parking infrastructure (e.g., street parking lanes and parking garages) which can contribute to an improvement in overall traffic flow, and a reduction in capital investment for commercial and residential real-estate development. Urban planning can be better centered around the true mobility needs of the citizens without sacrificing valuable space for vehicles that are inactive most of the time. A key challenge is the transition phase where traditional forms of car ownership and transportation coexist with new forms of mobility services (before true MaaS platforms are fully optimized). Another fundamental issue is determining the true cost of car ownership and establishing ideal cost structures for on-demand mobility services in order to replace the need of owning a car. This needs to occur without compromising subsidized public transportation which provides affordable transportation for low-income groups.

Download or read book Unsettled Technology Domains for Pathways to Automotive Decarbonization written by Jody Emlyn Muelaner and published by SAE International. This book was released on 2020-07-22 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Replacing fossil-fueled vehicles with battery-electric ones is a risky strategy. It is likely to be limited by the supply of metals critical to battery and solar cell production, and the investment required in decarbonized electricity. Using hydrogen to store renewable energy would greatly reduce efficiency, further increasing the investment required to decarbonize the electricity supply. The lowest technical risk and most economical pathway to decarbonization is reducing private car use. Shorter journeys would be made by walking and cycling – also known as “active travel” – with public transport used for most longer journeys. Realizing this cultural change in transport behavior will first require comprehensive networks for safe and enjoyable active travel, which separate walking and cycling. All locations should connect to either a fully segregated cycleway or traffic calmed roadways with a maximum speed of 30 kph. Active travel investment can save money due to improved public health, eliminate the 11% of carbon emissions caused by short car journeys, and facilitate public transport by empowering people to reach their final destination. Bicycle manufacturing is growing rapidly and further innovations in transport cycles and other lightweight vehicles compatible with an active travel infrastructure will boost this growth. Increased use of public transportation is vital to efficiently use the limited availability of decarbonized electricity. Autonomous vehicles in private use may increase vehicle miles, but autonomous operation within public transportation systems could be transformative. The remaining private cars, buses, and heavy goods vehicles could be electrified more cost effectively using electric road systems. These enable unlimited range and smaller batteries, with the lowest societal cost of any private car-based decarbonization pathway. Although users may pay higher road tax or tolls for the infrastructure, this is easily offset by greatly reduced vehicle costs and improved efficiency. Electrification needs to be brought initially to city bus networks and heavily used transport corridors. Wider use will require standardization and investment at the federal level or continental level.

Download or read book Unsettled Topics Concerning the Field Testing of Automated Driving Systems written by Bob McQueen and published by SAE International. This book was released on 2019-12-19 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automated driving systems (ADS) have the potential to revolutionize transportation. Through the automation of driver functions in the application of advanced technology within the vehicle, significant improvements can be made to safety, efficiency, user experience, and the preservation of the environment. According to the US Department of Transportation [1], there are more than 1,400 cars, trucks, buses, and other vehicles being tested by more than 80 companies across the USA. Implementation of ADS technology is well advanced, with many sites across the USA incorporating automated vehicles (AVs) into wider programs to apply advanced technology to transportation. Discussions with the public sector’s implementing agencies suggest that one of the barriers to faster progress lies in the lack of consistent and standardized field-testing protocols. This report looks at the state of the art of field testing for ADS and identifies areas for improved consistency and standardization. It will define the problem to be addressed by AVs and the challenges associated with the introduction of such vehicles and open-road situations. In particular, the report will look at the possibilities for big data and analytics to enable the sharing of lessons learned and convergence on standard field-testing approaches.

Download or read book Micromobility User Input and Standardization written by Brittany Eastman and published by SAE International. This book was released on 2023-07-18 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micromobility is often discussed in the context of minimizing traffic congestion and transportation pollution by encouraging people to travel shorter (i.e., typically urban) distances using bicycle or scooters instead of single-occupancy vehicles. It is also frequently championed as a solution to the “first-mile/last-mile” problem. If the demographics and intended users of micromobility vary largely by community, surely that means we must identify different reasons for using micromobility. Micromobility, User Input, and Standardization considers potential options for standardization in engineering and public policy, how real people are using micromobility, and the relevant barriers that come with that usage. It examines the history of existing technologies, compares various traffic laws, and highlights barriers to micromobility standardization—particularly in low-income communities of color. Lastly, it considers how engineers and legislators can use this information to effectively innovate micromobility devices and regulatory frameworks that meet the needs of communities while effectively outlining guidelines for providers. These are processes must happen concurrently and inform one another. Click here to access the full SAE EDGETM Research Report portfolio. https://doi.org/10.4271/EPR2023015
