 Urban Air Mobility Implications for Intelligent Transportation Systems
                  draft-templin-ipwave-uam-its-00.txt

Abstract

   Urban Air Mobility concerns the introduction of manned and unmanned
   aircraft within urban environments, while Intelligent Transportation
   Systems have traditionally considered only terrestrial vehicles
   operating on city streets and highways.  This document considers the
   implications for introduction of low-altitude aircraft within urban
   environments operating in harmony with ground transportation.

1.  Introduction

   Urban Air Mobility (UAM) concerns the introduction of manned and
   unmanned aircraft within urban environments.  NASA has initiated a
   program known as the Urban Air Mobility grand challenge with the goal
   to promote public confidence in UAM safety and facilitate community-
   wide learning while capturing the public's imagination [UAM].

   Autonomy will play a pivotal role in the acceptance of low-altitude
   operations for aerial vehicles operating in harmony with traditional
   ground transportation and pedestrian traffic.  The UAM vision
   therefore builds on evolving works on Unmanned Air Systems (UAS),
   including the NASA UAS Traffic Management (UTM) service model [UTM].

   Use cases for autonomous aircraft in the UAM vision are endless, and
   include personal air vehicles, flying taxis, parcel delivery, law
   enforcement and countless others.  Major industry leaders such as
   Airbus [AIRBUS] and Boeing [BOEING] have accordingly begun to
   articulate their UAM strategies.  Programs such as Uber Elevate
   [UBER] anticipate deployment as early as within the next 2-5 years.

   With the advent of the UAM vision and its related initiatives,
   questions arise as to how the new model will be harmonized with the
   existing terrestrial mobility environment.  Directions for
   modernizing terrestrial mobility are emerging in programs such as the
   US Department of Transportation's Intelligent Transportation Systems
   [ITS] and anticipate an increasing role for Vehicle to Vehicle (V2V)
   and Vehicle to Infrastructure (V2I) communications.  The IETF
   recognizes this need and has formed the IP Wireless Access in
   Vehicular Environments (IPWAVE) working group with charter to produce
   a document that will specify the mechanisms for transmission of IPv6

   datagrams [RFC8200] over dedicated short-range wireless
   communications media.

   This document anticipates a need to provide a unified V2V and V2I
   service for all urban mobility agents, including both terrestrial and
   airborne.  Urban air vehicles will employ Vertical Takeoff And
   Landing (VTOL) and will operate at altitudes below 400 feet, such
   that coordinations with terrestrial vehicles will be inevitable and
   commonplace.  This work therefore proposes that urban air vehicles
   also employ a short-range V2V / V2I communications capability using
   the same types of wireless networking gear used in the terrestrial
   domain (e.g., DSRC, C-V2X, etc.).

   As stated by the Boeing CEO in a January 23, 2019 press release,
   think of the urban mobility landscape as evolving from a two
   dimensional to a three dimensional environment.  Vehicles both on the
   ground and in the air will therefore need to coordinate with one
   another on a V2V and V2I basis even when supporting communications
   infrastructure such as cell towers are unavailable or otherwise too
   congested to support realtime exchanges.  The ipwave working group is
   therefore advised to consider the rapidly emerging and inevitable
   Urban Air Mobility future.

2.  Terminology

   Terms such as Intelligent Transportation Systems (ITS), Urban Air
   Mobility (UAM), Unmanned Air Systems (UAS), UAS Traffic Management
   (UTM) and many others apply to the emerging urban mobility landscape.
   IETF keywords per [RFC2119] are not applicable within the scope of
   this document.

3.  Applicability

   Urban Air Mobility and Intelligent Transportation System concepts
   apply within all major urban areas worldwide.

4.  Implementation Status

   Early prototyping and testing are underway.

5.  IANA Considerations

   This document introduces no IANA considerations.

6.  Security Considerations

   Communications networking security is necessary to preserve the
   confidentiality, integrity and availability necessary for V2V and V2I
   coordinations.

7.  Acknowledgements

   Discussions on the IETF ipwave list (its@ietf.org) helped motivate
