Carried out by &

Study funded by the German Federal Ministry of Transport, Building and HousingDirectorate Road Construction, Road Traffic

Considerations on the development of TERN:

• Development of a all over Europe unique, proven functional intermodal TEN-T (TERN)

(functions not being defined by any local or regional traffic demand – but by the need to provide connections of intermodal as well as supra-national importance)

• The function of the network being monitored regularly and adapted to changing infrastructure, economic structures as well as possible extensions of the community

Intention of CEDR SG TERN / Aim of the study

• Method/principle to merge the different existing international road networks on a functional basis

– E-Road Network, TERN, TEM should in the long run be transferred into one unique international road network to be more effective

• Tool to monitor/verify and amend the functional network in the case– of the amendment of national master plans or

– the extension of the network area

• Tool for determing and monitoring the prevailing function of each element of the network– as a basis for special ranking and funding the maintenance and con-

struction of network elements

Aim: Development of a formalised procedure to interpret the TEN-T functional requirements in order to introduce both networks into

a unique international road network – with comparable functional network conditions all over Europe

TERN, “TINA”, TEM- Roads(existing and planned links)

Principle of methodological approach

Network, Zoning system, Zone characteristics

Interconnection matrices

Calculation of indicators• Connectivity of links• Directness

Route choice and Assignment of relations

Assessment• Variation of threshold value of the

indicators• Superpositioning of indicators

Defining the network • Defining basic network and hierarchical levels

• Important role in long-distance transport =

(a)Connections between adjacent zones

(b)Connections between zones and neighbours to adjacent Zones

(c)Connections of conurbation areas (all to all)

(d)Connections of conurbation areas (nearest 5 conurbations)

(e)Connections of conurbation areas (nearest 10 conurbations)

• Intermodal links =

(a)Connections between zones and nearest airport

(b)Connections between zones and nearest seaport

Summarised Statistics



14

About 97 % of all links of the existing TERN and E-Road network

(average for the complete net work) fulfil at least one functional

requirement as confirmed by the functional assessment, which means

that the present definitions by the countries mostly meet the

functional requirements as made operational in the model already.

The roads which are both existing TERN and E-Road (length approx.

74,000 km) fit to a comparably higher extent (77%) the Major Network

than the roads which are ‘TERN only’ (45%) or ‘E-Roads only’ (48%)

which shows the special importance of the group ‘TERN and E-roads’

for the international road transport.



Findings of the application of the method (1)

15

Beside these results and referring to the entire Study Network, the

functional analysis of the network of each single European country

also might be of interest. Substantial differences of the functional

classification might occur in some countries according to the approaches

carried out here. Reasons may be the imbalance of density, structure

and classification of the network as well as the size and location of

conurbations in different countries. However, the analysis of network

density and population density shows a harmonised distribution of the

network referring to the different countries.



Findings of the application of the method (2)

16

Discussion of the method• Advantages of the method

– possibility of the implementation of a hierarchical structure/system of the TERN

– definition of an international/large scale network of “one mould”

– definition of an intermodal network for special functional requirements

• Critical aspects of the application and practical use of the model

– the formalistic procedure hardly meets conventional views of network planning and construction

– the acceptance of the results requires international/large scale interests/visions

– the procedure seems to restrict political decisions and to neglect national peculiarities



17

The attempts undertaken to define a future Trans-European road network

as a combination of the present TERN and the E-road network show that

– in principle – logical functional and – from national points of view - useful

coherent network structures can be achieved by the methodological

approach developed here.



Conclusion
