Transcript

  • 1. • Large scale investment in ITS Systems• Adaptive Traffic Systems• CCTV• VMS• Parking Systems• Footfall Counters• Large Data Storage
  • 2. Traffic Flow DataJunction Operation Pedestrian Flow
  • 3. DCC has Real Time data on Dublin Bus FleetAllow IBM access to data and provide server space.1000 vehicles provide location information every 20 – 30 Seconds Provide Visualisation of data Allow a city wide view but also provide the means of seeing where problems are. Handle verbose XML SIRI standard records.
  • 4. Real Time data Issues• What is real Time data :- •Depends on what the final use of it is.•Real Time data to DCC is data which we collect in real time, analyse and use it to adjust alert or inform in as close to real time as possible.• Real Time data goes “stale “ very quickly and becomes historic data`.
  • 5. Real Time Issues • Take two systems as an example • SCATS Traffic Control System • Real Time Passenger Information• SCATS has an “ITS “ port which provides a means of retrieving data from SCATS in Real Time. This is a licenced product and around €20,000 per connection, also multiple connections will have implications for server processing and architecture.• THE RTPI system also has a SIRI interface which is a licenced product and costs €25,000 per connection. Again multiple connections has severe implications for server processing etc.
