  2. Agenda • ETISplusmain principle • ETISplusroad network model • ETISplusimpedances • ETISplusdemand data • ETISplus long-distance coach data • Conclusions

  3. ETISplus: mainprinciple • Usage of as many ›original‹ data as possible • Usage of generated data to fill data gaps

  4. ETISplusroadnetwork model: General items • Scopeof the road network model: Comprising network and freight terminals • Purpose of the road network model: modelling passenger and freight transport demand in Europe, i.e. computation of transport impedances, assignment, external impacts • Basis: TRANS-TOOLSversion 2 network model

  5. ETISplusroadnetwork model: Main link attributes • Unique ID • Nodes (f-node, t-node) • (Maximum) speedfor passenger cars/ trucks • Road type • Number of lanes per direction

  6. ETISplusroadnetwork model: Main link attributes[continued] • Road charges (generic toll versus link-specific toll) • Average fuel costs, considering country-specific fleet characteristics • Information on ferry connections • Information on country border crossing • Traffic count data, differentiation by vehicle type

  7. ETISplusroadnetwork model: General methodology  

  8. Geographicalscope – pre-ETISplus

  9. Geographicalscope – ETISplus

  10. ETISplusroadnetwork model

  11. Main terminal attributes • Inland freightterminals • Unique ID • Name • Country and NUTS-3 region the terminal is located in • Connectivity withother modes • Working hours per day • Working days per week • Services per week

  12. Road impedancedata – generalitems • For modelling purposes, data mainly required at the level of O/D relations (NUTS-3NUTS-3 regions) • Main impedance data:travel time; travel distance; user costs (fuel costs, road charges) • ‘Observed data’ rarely available:=> computation of impedance data under application of models

  13. Road demanddata • Two types of demand data: • Demand at the level of O/D relations • Demand at the level of network links • Demand at the level of O/D relations:to be estimated, since almost no observed data available • Demand at the level of network links:partly collected, partly modelled

  14. Road link loaddata – trafficcountdata UN/ ECE Availabilityof UN/ ECE roadtrafficcountdata Network topology: TRANS-TOOLS vs. UN/ ECE

  15. Road link loaddata – rawformats: GIS data

  16. Road link loaddata – rawformats: thematicmaps

  17. Road link loaddata – rawformats: tables

  18. Road link loaddata – overviewofmethodology +  NATIONAL SOURCES INTERNATIONAL SOURCES CONSOLIDATION PROCESS EU27 countries, + Switzerland, Norway, + Accession countries, +Candidate countries, + Other neighb. countries  TEN-Tec EUROSTAT SOURCE DATA FORMATS ROAD NETWORK MODEL

  19. Data on long-distancecoachservices Mappingof most relevant scheduled long-distance coach services Demand at the level of O/D relations, based on level-of-service data Data on fares per country

  20. Conclusions • Very few ‘observed’ data are available at the level of O/D relations (demand, supply) => requirement to model data • The useofmanifolddifferent roadnetworkmodelsfordifferent purposes, such as • Network model A, usedformodellingwithin TRANS-TOOLS; • Network model B, usedforcollectinginfrastructure-relateddatafor TEN-Tec; • Network model C, usedforcollectingtrafficcountdataby UN/ ECE, • Network model D, usedforcollectingtrafficcountdata in country D, • … • imposesrelevant efficiencyrestrictionsfortransportmodellers

  21. Conclusions[continued] • Several of the data gaps within TRANS-TOOLS will be bridged by ETISplus • ETISplus will clearly enhance the technical capabilities of TRANS-TOOLS, e.g. in terms of • Extension of the geographical scope of data availability • Enhanced status of quality of network model (topology, attributes, link alignment) • Inclusion of freight terminals • Enhanced status of level-of-service and demand data for long-distance coach transport • Refinement of traffic count data
