6. HackTrain – our challenges for you Incident  dura0on   es0mates     •  Currently  based  on  ‘best  guess’   and  experience   •  Seeking  smart  soluFon   •  Using  historical  data   •  Accuracy  needs  to  improve   •  Incident  ‘types’  are  the  challenge     Journey  check       •  Currently  based  on  ‘best   guess’  and  experience   •  Seeking  smart  soluFon   •  Using  historical  data   •  Accuracy  needs  to  improve   •  Incident  ‘types’  are  the   challenge  
7. Na0onal  Public  Transport  Access  Nodes  (NaPTAN)   NaPTAN  is  Britain's  naFonal  system  for  uniquely  idenFfying  points  of  access  to  public   transport.       It  is  a  core  component  of  the  naFonal  transport  informaFon  infrastructure  and  is  used   by  a  number  of  other  UK  standards  and  informaFon  systems.       There  is  a  NaPTAN  record  for  every  bus  stop,  railway  sta0on,  airport,  ferry  terminal   etc.  in  England,  Scotland  and  Wales.  Record  a8ributes  include  co-­‐ordinates  (OSGR   and  Lat-­‐Long),  NPTG  locality  reference,  name  components  and  SMS  code   200MB  CSV  /  600MB  XML!   h8ps://www.gov.uk/government/publicaFons/naFonal-­‐public-­‐transport-­‐access-­‐node-­‐schema
