1 Floating Car Data in the Netherlands Aad de Hoog Ministry of Transport, Public Works and Water Management The Netherlands 1

2 Overview Setting the scene Concept, technique and results Dutch policy Future developments Conclusions 2

3 Setting the Scene Innovation programme Roads to the Future Vision: road director as well as road user need complete information PRELUDE is a demonstration rather than a final solution 3

4 Concept, techniques and results Probe cars Communication Map-matching Computing traveltimes Distribution of traffic information Organization 4

5 The concept of Floating Car Data GPS GSM Demo GPS GSM GSM Server FCD computer FCD Demonstration computer GPS GSM TIC-NL distribution 5

6 Probe Car 60 cars in region of Rotterdam, owned by 4 fleetowners (lease/taxi/courier) Equipped with DGPS and cellular phone (GSM) Traveling more than km in the study period of 4 month The coverage of DGPS > 95%, accuracy within 5 m 6

7 The Study area Europe Rotterdam The Netherlands 7

8 Communication Cellular phone (GSM) and ISDN (Fast connect), using data channel mode of GSM Less than 5 % retry Data transfer less than 2 seconds per car per 5 minutes Cost typical $2,- per car per month for communication Privacy guaranteed 8

9 the on-board unit determines every 10 seconds the GPS position and speed of the vehicle the on-board unit transmits every 5 minutes the stored positions via GSM-data to the FCD centre 9

10 Map-matching DGPS-data is matched on the detailed map of Rotterdam (> 95% success) Covered vectors are computed using routing algorithms and network properties (e.g. one way lanes) 10

11 Raw and matched positions 27 sec. each 10 second a position 11

12 Travel time calculation Travel times are calculated on all detailed road segments when sufficiently covered by one or more probe cars A travel time is deduced for more than 85 % of all road segments driven by the probe cars 12

13 Distribution of information In-car: using RDS-TMC Pre-trip: Internet on: 13

14 The Internet site 14

15 Organizational aspects Key success factor was co-operation with Fleetowners Industry Local authorities Fleet coordination takes more effort than expected 15

16 Dutch Policy The government stimulates market mechanisms and is in dialog with the industry about the different roles Data collection using FCD is a task for the private sector The public sector is one of the clients for traffic data from FCD FCD fits in the policy for chain mobility: door-to-door travel information 16

17 Future Developments Further development of products by industry make the connection with May Day and AVLsystems use of smart in-car terminals standardize the used protocols Government will stimulate market initiatives for medium scale pilot (>1000 cars) 17

18 Future Developments FCD will not come in place of the inductive loops, but fits in a multiple monitoring concept There will be further analyses of the data All datasets will be made available e.g. through the Internet 18

19 Conclusions FCD does work in a city environment the communication costs are low and can still be reduced further Travel information for door-to-door mobility is within reach FCD is on the agenda based on real facts There is still a step to make towards national coverage of FCD in the Netherlands 19
