Big Transport Data in Thessaloniki. What are the
benefits?
Thessaloniki on the map
~1.400.000 inhabitants~450.000 private cars & 20.000 motorcycles1.300.000 daily trips1 (+1) public transport operator for urban trips~35 public transport operators for extra-urban trips1.950 taxis6.433 kms of streets8,8 kms of dedicated bus lanes12 kms of dedicated bicycle lanes89,4 kms of ring road197.696 parking places
Existing ITS layout•Periphera

Thessaloniki Mobility lab
Mobile sensors in Thessaloniki• Stationary sensors network: Point to point tracking of MAC
ids along the network through 43 Bluetooth device detectors.▫ Travel time estimation▫ Route choice model calibration▫ Origin – Destination matrix estimation / Mobility patterns
estimation▫ Traffic flow extrapolation
• Dynamic sensors fleet: Floating Car Data provided in real time by a professional fleets composed of 1.200 taxis and 600 buses▫ Traffic status estimation (average speed)▫ Origin – Destination matrix estimation / Mobility patterns
estimation▫ Taxi/bus performance indicators
• Social media (geolocated tweets & Facebook check-in events)▫ Activity patterns estimation▫ Events / incidents detection▫ Attraction models estimation
Dynamic Sensors Data
Floating Car Data (taxis)▫Device ID▫GPS position (X, Y, Z)▫Orientation (degrees)▫Speed (km/h) ▫Timestamp ▫Zone▫Status
Floating Car Data (taxis)•1.200 vehicles (dispatching application)
▫Circulating 16-24 hours per day▫Pulse generated each 100 meters (10-12
seconds)▫500-2.500 pulses per minute
Floating Car DataReal time traffic conditions information based on a combination of traffic
modeling and real time measurements (traffic flow and speed)
Stationary Sensors Data
Bluetooth devices detectors• 43 detectors (EEA, SEE-ITS & EASYTRIP)
▫ 4 million detections per week (peak period)▫ 25.000 unique devices detected per day (one intersection)▫ 1 million “tracked” trips per week▫ 20.000 “tracked” trips per day (one path)
• More detectors installed in other cities and in Bulgaria (SEE-ITS & EASYTRIP)
Point to point BT networkReal time travel time provision to drivers (VMS, internet,
smart device)
BDE pilot in Thessaloniki
•Probe data that is used▫Floating Car Data (500-2.500 locations per
minute)▫Bluetooth detections (millions of daily
detections in 43 locations)•Services that are being implemented
▫Improved topology-based map matching▫Mobility patterns recognition and forecasting
