Taxonomy and Definitions for Terms Related to Shared Mobility and Enabling Technologies

Shared and Digital Mobility Committee
  • Ground Vehicle Standard
  • J3163_201809
  • Current
Published 2018-09-24 by SAE International in United States
This Recommended Practice provides a taxonomy and definitions for terms related to shared mobility and enabling technologies. Included are functional definitions for shared modes (e.g., carsharing, bikesharing, ridesourcing, etc.). Public transit services and other incumbent services—such as car rentals, shuttles, taxis, paratransit, ridesharing (carpooling/vanpooling), and pedicabs—are also included in the ecosystem of shared mobility services. This Recommended Practice also provides a taxonomy of related terms and definitions (e.g., station-based roundtrip, free-floating one-way, etc.). This Recommended Practice does not provide specifications or otherwise impose requirements on shared mobility.
 

A System of Systems Approach to Automotive Challenges

General Motors LLC-Gary Rushton
WSP USA-Oliver M. Hoehne
Published 2018-04-03 by SAE International in United States
The automotive industry is facing many significant challenges that go far beyond the design and manufacturing of automobile products. Connected, autonomous and electric vehicles, smart cities, urbanization and the car sharing economy all present challenges in a fast-changing environment which the automotive industry must adapt to. Cars no longer are just standalone systems, but have become constituent systems (CS) in larger System of Systems (SoS) context. This is reflected in the emergence of several acronyms such as vehicle-to-everything (V2X), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-grid (V2G) expressions.System of Systems are defined systems of interest whose elements (constituent systems) are managerially and operationally independent systems. This interoperating and/or integrated collection of constituent systems usually produce results unachievable by the individual systems alone, for example the use of car batteries as virtual power plants.This paper will (1) discuss automotive challenges the industry is currently facing, (2) provide an introduction into System of Systems Engineering (SoSE), (3) provide examples and case studies of successful SoSE, and (4) make recommendations on how to address the automotive challenges applying SoSE.

An Indirect Occupancy Detection and Occupant Counting System Using Motion Sensors

Chongqing University-Dawei Luo, Gang Guo
Ford Motor Company-Jianbo Lu
Published 2017-03-28 by SAE International in United States
This paper proposes a low-cost but indirect method for occupancy detection and occupant counting purpose in current and future automotive systems. It can serve as either a way to determine the number of occupants riding inside a car or a way to complement the other devices in determining the occupancy. The proposed method is useful for various mobility applications including car rental, fleet management, taxi, car sharing, occupancy in autonomous vehicles, etc. It utilizes existing on-board motion sensor measurements, such as those used in the vehicle stability control function, together with door open and closed status. The vehicle’s motion signature in response to an occupant’s boarding and alighting is first extracted from the motion sensors that measure the responses of the vehicle body. Then the weights of the occupants are estimated by fitting the vehicle responses with a transient vehicle dynamics model. This two stage approach is further used to determine how many occupants are staying in the car. The effectiveness of the proposed approaches has been verified in vehicle tests through a variety of…

Secure and Privacy-Preserving Data Collection Mechanisms for Connected Vehicles

Ford Motor Company-Yu Seung Kim, Pramita Mitra
University of Michigan-Dearborn-Huaxin Li, Di Ma, Brahim Medjahed, Qianyi Wang
Published 2017-03-28 by SAE International in United States
Nowadays, the automotive industry is experiencing the advent of unprecedented applications with connected devices, such as identifying safe users for insurance companies or assessing vehicle health. To enable such applications, driving behavior data are collected from vehicles and provided to third parties (e.g., insurance firms, car sharing businesses, healthcare providers). In the new wave of IoT (Internet of Things), driving statistics and users’ data generated from wearable devices can be exploited to better assess driving behaviors and construct driver models. We propose a framework for securely collecting data from multiple sources (e.g., vehicles and brought-in devices) and integrating them in the cloud to enable next-generation services with guaranteed user privacy protection. To achieve this goal, we design fine-grained privacy-aware data collection and upload policies that balance between enforcing privacy requirements and optimizing resource consumption (e.g., processing, network bandwidth). The optimal policy will be determined by the privacy index of the integrated multi-source data to be used by the specific service and the desired resource usage. Real-world experiments and privacy leakage analysis are conducted to address…

Flexible and Intermediate Forms of Transport as Part of a Package of Transport Demand Measures

University of Newcastle upon Tyne-J. D. Nelson, W. Saleh
  • Technical Paper
  • 1997-25-0232
Published 1997-06-16 by ISATA - Dusseldorf Trade Fair in United Kingdom
This paper is concerned with the evaluation of flexible and intermediate forms of transport and their contribution to the policy of Transport Demand Management (TDM). Several definitions of such measures are presented such as car pooling, car sharing and innovative telematics-based demanding-responsive transport services (DRTS). Results are presented from a survey completed as part of the DGVII-funded project AIUTO. As an example, the paper then concentrates on the evaluation of demand-responsive transport services (DRTS) completed as part of the DGXIII-funded SAMPO project (System for Advanced Management of Public Transport Operations). The SAMPO project has undertaken demonstrations of DRTS using advanced telematics technologies (ATT) in five test sites. The paper describes the techniques for evaluation that have been adopted for the measurement of key assessment priorities at each site. Concluding comments are presented on recommended best practice for TDM packages.
 

New technologies for professional car sharing

University of Siegen-U. Latsch
  • Technical Paper
  • 1995-25-0132
Published 1995-09-18 by ISATA - Dusseldorf Trade Fair in United Kingdom
Recently in many European cities so-called car-sharing organizations are established. Up to now most of this organization does not employ any technical systems to survey the use of their cars. But if car sharing wants to become a serious alternative to private cars, professional administration requires the use of modern technologies to avoid fraud and to simplify management. This paper gives an overview about the potentiality and problems of professional car sharing.
 

Intelligent Vehicle Management-The Use of Modern Communications Technologies in Car-Sharing Projects

Published 1994-06-16 by Verlag Des Verein Deutscher Ingenieure GmbH in Germany
Car sharing and car pooling present one solution to many of the problems associated with urban traffic congestion. This solution allows users the option to use a car when other modes of transport do not allow the planned trip to be readily achieved. The paper discusses different types of communication and traveler advisory methods which could lead to widespread public acceptance of this promising solution.The development of the COCOS electronic car-sharing system provides improved consumer acceptance, route booking and user billing. The University of Siegen has created a multifunctional electronic chip-card useable not only for COCOS, but also as a debit card for parking and public transport.
