2 Eckhard Szimba ETISPlus Road Data WorkshopETISplus: Road networks, impedances & link load data

Agenda

ETISplus main principle

ETISplus road network model

ETISplus impedances

ETISplus demand data

ETISplus long-distance coach data

Conclusions



Usage of as many ›original‹ data as possible

Usage of generated data to fill data gaps

ETISplus: main principle



Scope of 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-TOOLS version 2 network model

ETISplus road network model: General items



Unique ID

Nodes (f-node, t-node)

(Maximum) speed for passenger cars/ trucks

Road type

Number of lanes per direction

ETISplus road network model:Main link attributes



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

Main terminal attributes



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

Road impedance data – general items



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

Road demand data



Network topology:TRANS-TOOLS vs. UN/ ECE

Availability of UN/ ECE road traffic count data

Road link load data – traffic count data UN/ ECE



Road link load data – raw formats: GIS data



Road link load data – raw formats: thematic maps



Road link load data – raw formats: tables

Road link load data – overview of methodology



Data on long-distance coach services

Mapping of 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



Conclusions

Very few ‘observed’ data are available at the level of O/D relations (demand, supply) => requirement to model data

The use of manifold different road network models for

different purposes, such as

Network model A, used for modelling within TRANS-TOOLS;

Network model B, used for collecting infrastructure-related data for TEN-Tec;

Network model C, used for collecting traffic count data by UN/ ECE,

Network model D, used for collecting traffic count data in country D,

…

imposes relevant efficiency restrictions for transport modellers



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
