2
Direct data connection from a vehicle to another road object
No intermediate infrastructure like cellular stations etc.
To exchange data with moving transport in real time
Vehicle to Vehicle (V2V) + Vehicle To Infrastructure (V2I) = V2X
4
Road Side Unit (RSU) installed as a part of active road side, toll
equipment, traffic light, etc.
On Board Unit (OBU) installed on the vehicle
Usually RSU not just transfer data, but process it and do decision making and controlling actions.
OBU may be passive (simply respond RSU requests) or active.
5
Collision prevention
Intelligent traffic management
Toll roads
Safety and video surveillance
Data gathering from autonomous vehicles (isolated and temporary isolated fleet)
Remote diagnostics
Backup data channel
Driver/passenger information
6
Very fast connection set up (no long handshake and short data path)
Predictable response time
Location based approach
Distributed data processing (no or limited functions of a central server)
Real time control and real time feedback
7
There are no technologies which can fully replace V2X or be fully replaced by V2X.
However in some solutions V2X can alternate:
CEN DSRC and other transponder / RFID based approaches for shortdistance low speed communications
Cellular network (including 3G and 4G)for long distance high speed datatransfer

Initially V2X was initially designed for collision prevention
Each car manufacturer has its [good looking] demo of how life can be cool with no accidents if equip all vehicles with V2X-based collision prevention system
It will be only working if most of vehicles equipped…
…and nobody knows how to do it.
11
Currently V2X is usually based on IEEE 802.11p, so it is WiFi optimized for moving nodes
Reduced channel width
Reduced handshake procedure
Longer distance data transmission
Unified (or theoretically unified) protocols on top
12
Two systems of standards: IEEE and ISO
Each manufacturer/deploying company selects what to use
Nobody fully meet standard, just declare: no real interoperability
IEEE 802.11p for raw data transfer
IEEE 1609 (WAVE) for exchange protocols
ISO CALM FAST for ITS systems architecture
13
Very fresh (WAVE is just completed)
“War of standards”
No real interest of OEMs
No public implementations (just very early attempts)
Too sophisticated for some tasks
ITS oriented
14
15
Intelligent Transport Systems
Autonomous fleets, mining equipment etc.
Security services
No real competition on the market [yet]. All projects are special and one goal, one customer and one OEM focused
ITS Integrators (Kapsch, Autostrada)
Tier One companies (NEC, Denso, Continental)
Independent OEMs (Cohda, Unex, Compo)
Academic institutions
Almost all aproaches (except Cohda and some others) are based on upgrade of existing 802.11 solutions
17
Market is just at start of the growing
All projects are limited and usually sponsored by governmental or municipal organizations
Usually projects are dedicated to given OEM due to non-business decisions
Usually one OEM provides all IT infrastructure
Almost everything is proprietary and closed source
No collaboration between market players except academic and standardizing works
18
All products are expensive:
Low price for OBU is $2000, usually >$3000. RSU is much higher (for almost WiFi!)
All products are unique.
Almost nothing available off the shelf
Very small volumes
19
20
Market needs a reference implementation
It can stop the “war of standards”
It can help reducing R&D costs
It can give a common basis for interoperability
It can involve wide community of developers
It can make devices cheaper and available for low cost projects and small companies
21
IEEE 802.11p is almost WiFi, IEEE 1906 is just a stack
RSU is very similar in design to WiFi AP enabled industrial computer
OBU is very similar in design to WiFi endpoint enabled ECU/TCU
No significant barriers to use Linux and OSS solutions. Componentality makes it for 2+ years, several other companies (like NEC and Unex) do the same without publishing these efforts
22
OpenWrt
ATHxK drivers
WAVE library
ITS applications
…and nothing else!
23
It opens absolutely new and fresh market for automotive companies
IVI market is full of OEMs and suppliers
IVI is in crisis of ideas
ECU doubts in open source solutions
ECU is complicated and has liability risks
ITS is still new, growing and has a number of opportunities
