V2X Applications…
Navigation/LBS/PoI
• GPS navigation
providing info/content
to the driver/ passenger
Commerce
• Mobile payment
system (charging tolls,
parking fees)
• Premiums for car
insurance correlated to
driving patterns
Maintenance/Optimization
• Remote diagnostic application
• Telemetry to collect data to
fine tune car performance
monitoring
Safety/Security
• In-vehicle tracking system
• Automatic security distance
maintaining system
Classes of V2X Applications
Cooperative Road Safety – Primarily refers to ultra-critical safety requirements; ◦ example includes collision avoidance, pre-crash sensing,
emergency hard-braking, etc.
Cooperative traffic efficiency – deals with traffic fluidity; ◦ example includes traffic light optimal speed advisory,
congestions alerts and new route suggestions, etc.
Cooperative local services – provides on-demand information on commercial/non-commercial stuffs; ◦ example includes maps update, e-advertising, media
download, etc.

An Emergency Response Web Application
• Detect that a crash has occurred
• Determine the location of the crash
• Send out an Emergency SMS to the pre-specified emergency
numbers about the crash with location information
Tizen Vehicle APIs Provides getting and setting data items
Mechanisms for event based updates to requested data items
Implements a method for a Web application to query for supported data items
get(eventlist, successCB, errorCB)
• Retrieve the specified data values, or all data values if blank
set(eventlist, valuelist, successCB, errorCB)
• Set the specified data values
getSupportedEventTypes(type, writeable, successCB, errorCB)
• Retrieve the list of events available on the platform
subscribe(eventlist, successCB, errorCB)
• Subscribe to update events for the specified data items
unsubscribe(eventlist, successCB, errorCB)
• Unsubscribe from update events for the specified data items

Example 2
Re-Routing under Crash Notification
Gets the crash information from the cloud server.
It then calls
◦ the geo location API’s and gets the current location of the vehicle from the location manager.
◦ the mapping API’s to calculate the distance to the crash location and displays it.
◦ the rerouting API’s from the mapping service rerouting by avoiding the crash location.
Note: the MapQuest open data API’s are used.
