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

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 …)

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

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
