Definition « Floating Car Data is a method to determine the traffic speed on a road
network »
Principle Vehicle positions and speeds are
measured via : Cell phones On board GPS units
• A traffic server generates traffic speeds for each road segment at each period of time
• These information are logged in database
Usages Traffic studies through historic FCD data Real Time Traffic Management

Using FCD for Traffic Studies
Using FCD for traffic studies
At sanef, we have been using FCD information since 2010
We have used FCD historic data for traffic studies To understand specific traffic situation Study mean travel time Measure traffic jam intensity
Can be used in before and after studies e.g. : to evaluate the impact of a traffic management
measure like variable speed limits e.g. : to evaluate the impact of replacing toll booth by free flow
tolling
Automatic generation of traffic indicators (congestion length, lost time, space/time diagram …)
Using FCD for traffic studies

Real Time FCD data can be used for :
Travel time calculation
Overview of the traffic states on a road
network
Generate traffic alerts
Using FCD for real time applications
11
Journey time calculation – Good accuracy
– Can be used to inform our
customers on travel time outside of our network (example : down to the city centres)
– No infrastructure required

Monitoring real time traffic speeds
– Can be used on all roads
• Your own network • Neighbouring network
– Can be used to detect and follow traffic events
• Traffic jam length and evolutions • End of event

Conclusion
13
3 main advantages for using FCD information FCD has definitely become a reliable source of
information for traffic studies
FCD quality is now mature enough for real time traffic monitoring and travel time calculation
FCD main advantage consists in being available almost anywhere, anytime without infrastructure deployment
