Conclusion & Outlook5
Requirements of the Extended Navigation Application
• Enrich the navigation application by value added real time traffic and traveler information
• Consider traffic information provided by different services and thus by different protocols & standards (in SIM-TD traffic info over IP, C2X Message over ITS G5)
• Create a single interface to the navigation core to provide the needed traffic
4th ETSI TC Workshop4th ETSI TC Workshop
• Create a single interface to the navigation core to provide the needed traffic information � navigation should not care about the different traffic info data sources
• Resolve, map match and display these information on the map• Consider the real time traffic information for route calculation and rerouting

database
• Collects all traffic related information provided by the different SIM-TD components listed above
• Resolve and map match the traffic info depending on the attributes of the concerned road link
• Display traffic events on the map• Oversee traffic situation for a planed route• Plan alternative route in case traffic problems occur on the
initial planed route

Conclusion & Outlook
Enhancement of navigation by new performant traffic information services is mandatory for today ITS landscape
Since different standards and protocols will co-exist, it is important to unify the traffic info interface to the navigation to simplify the data handling

Conclusion:
4th ETSI TC Workshop4th ETSI TC Workshop
important to unify the traffic info interface to the navigation to simplify the data handling
A modular sensing platform approach should form the base for collecting and aggregating the data
Resolving redundacy and conflicts of collected traffic information should be taken into consideration in the next step
