Harmonizing Alpine traffic data

  1. 1. The AlpCheck Information System AlpCheck Final Conference, Venice June 26, 2008 PARADIGMA Rudolf J. Bauer 1
  2. 2. Purpose and scope of the Information System  To collect and combine high quality information on Alpine transport – Emphasis on road based cargo traffic – Using existing surveys, count data from highway operators, data collected from the pilots  To provide analytic capabilities to understand the data and to use it for planning purposes – Operational, tactical and strategic level  To deploy cutting edge business intelligence technology in the domain of transportation planning – Multi-tiered architecture – Documenting the genealogy of the data – High performance processes and data base management systems © Copyright 2008 Paradigma Unternehmensberatung GmbH 2
  3. 3. Traffic data sources in the ALPCHECK Information System Data Set Type Description CAFT O/D Cross Alpine Freight-Transport/BMVIT survey ASFINAG Count hourly count at selected highway locations in Austria 2004-2006 ASPI Count hourly count at selected highway locations from Autostrade per l'Italia VENT Count Alpcheck Pilot, Ventimilia TF Count Frejus Tunnel Pilot Data TMB Count Mont Blanc Tunnel, Pilot Data TGSB Count Grand Sant Bernardo HTLS O/D SLALA/IREALP Pilot data WIM O/D Venice/Stuttgart Pilot data OMEGA Count Slovenia Pilot, Traffic Count © Copyright 2008 Paradigma Unternehmensberatung GmbH 3

  13. 13. Transformation and load process (ETL) Job controlling the update of OMEGA data 1. Set up parameters and find new input files. 3. If all files have been used in update, create and install new SuperSTAR database. 2. If new files available, iteratively update staging area. © Copyright 2008 Paradigma Unternehmensberatung GmbH 13

  15. 15. Benefits, lessons learned      BI Technology can be successfully applied to support traffic planners The ALPCHECK system is scaleable and performs to expectations Powerful and easy to use analysis tools support the traffic planner Heterogeneous data can be compared to enhance the analysis process Readily available descriptions support the interpretation of the data © Copyright 2008 Paradigma Unternehmensberatung GmbH 15
  16. 16. ALPCHECK – the way forward  [ALPCHECK information system] – extraction from feeder systems (FTP) – Automatic, scheduled transformation and update – Data interpretation and analysis (query and analysis)  [Decision Support System] – Model supported interpretation and analysis – Analyse traffic data in combination with trade data – Data presentation (geo-referenced user interface)  [Infomobility] – Expansion of scope (multimodal, passenger traffic) – Dynamic acquisition of real time traffic data – Expand usage from planning to traffic management © Copyright 2008 Paradigma Unternehmensberatung GmbH 16
