DSRC Deployment Issues: An OEM Perspective

DSRC Deployment IssuesAn OEM Perspective

• ITS America Annual Meeting
• May 19th, 2003
• Christopher Wilson

2
Automotive DSRC Use Telematics Applications

• Telematics is still moving forward and will not
  wait many more years.
• There clearly is revenue here somewhere
• Cell phone is primary competition
• Applications include
• Traffic
• Probe vehicles
• Preventative diagnostics
• Entertainment downloads
• Electronic Toll collection
• Ordered from cell phone appropriate to DSRC
  appropriate (moderate hotspot coverage)

3
Vehicle Safety Communications Consortium

• Facilitate the advancement of vehicle safety
  through communication technologies.
• Identify and evaluate the safety benefits of
  vehicle safety applications enabled or enhanced
  by communications.
• Assess associated communication requirements
  including vehicle-vehicle and vehicle-infrastructu
  re communications.
• Contribute to 5.9GHz DSRC standards and ensure
  they effectively support safety.

Automotive DSRC Use Safety Applications

• The following are viewed by the automotive
  manufacturers as having the highest potential
  benefit for safety
• Traffic signal violation warning
• Curve speed warning - rollover warning
• Emergency electronic brake lights
• Pre-crash sensing
• Cooperative forward collision warning
• Left turn assistant
• Lane change warning
• Stop sign movement assistance
• The safety benefit appears significant given the
  range of options open to OEMs, and these are
  uniquely supported by DSRC (among communications
  schemes)
• Key Question How closely are Telematics
  Safety businesses linked?

5
DSRC Motivation

• DSRC provides unique capability for vehicle
  safety and the cooperation of vehicles with the
  roadway (traffic and operations).
• This may be the only unique benefit of DSRC in
  the long run.
• 802.11a, 802.11g
• GPRS, G3 telecoms
• Specific applications
• Point-to-point, time critical, data relays
  (car-to-car, intersection violation, collision
  warning)
• Low value, high volume data dumps from vehicles
  (probe, status monitoring)
• High volume, local, data feeds to vehicles (map
  updates, other vehicles)
• There are many other applications that can use
  DSRC, but also 802.11x, G3 in the future.
• How do we get DSRC deployed?

6
Deployment Issues

• Unable to support large scale rollout without
  early returns. (especially now).
• There does not appear to be enough benefit to the
  OEMs to deploy DSRC on their own. We must find
  partners with their own, complementary benefits.
• The automotive industry has traditionally been
  dictated by OEMs. We are not used to dependent
  relationships on complementary industries.
  (paradigm shift)
• Automotive industry deploys simultaneously at low
  levels across US. Can not efficiently deploy to
  local markets.
• There is no single entity that can ensure
  standards, let alone deployment across state and
  regional infrastructure
• Who do the first systems out talk to? The
  chicken and the egg.

• Diagnostics
• Differentiation through services to driver
• Relationship management

• Congestion info
• Origin-destination pairs
• Road condition

Action plan for DSRC deployment

• The actions required to move forward appear to be
  the following
• Create a vision for cooperation between vehicles
  and infrastructure at a high level.
• Create a mechanism for consensus and standards
  compliance within the infrastructure community.
• Develop the business case for cooperation.
• Demonstrate the technology in a full-scale
  initial deployment test in a selected geographic
  location, then go national quickly.
• Phase in the visible applications
• Probe traffic, entertainment
• Point to point safety applications
• Multi-car safety applications
