The main purposes of ProData is to be able to make road inspections and register faults for later measurements, register what has been done, make different kinds of inventories. The idea is that every vehicle/driver has access to a hand terminal and a GPS receiver (Global Positioning System). All conceivable road maintenance activities are pre-programmed in the hand terminals, which are mounted in the vehicles and connected to the GPS. In order to simplify the handling of the handterminals, all activities are organised in different lists. Each list refers to a field of operations (winter road maintenance for instance) and contains all the activities that belong to that particular field. ProData is today used for/as quality assurance, basis for invoicing, basis for payment to subcontractors, basis for future calculation and planning of different activities. ProData will tomorrow be used for/as EDI-handling of a whole maintenance contract, an integrated part of our other follow-up systems, direct information via communication radio to i.e. traffic information central, automatic registration of the amount of spread salt on different stretches.
