1. 1 Analyse the Report “Towards a European Main Road Network” Meeting in London, 08/09th November 2006 Presented by Brit Colditz, German Federal Ministry of Transport, Building and Housing Project Group Planning Working Package WP3 - Analysing the existing networks

2. 2 Report “Towards a European Main Road Network” Part I:Study on Combining of TERN/TINA and E-Road Networks on the Basis of the Functional Requirements of TEN-T-Guidelines (Prepared by WERD SG TERN, 2002) Part II:Study update and extension to the East Functional evaluation of the relevance of the European trunk roads for TERN taking into account the accession countries of Eastern Europe (Prepared by CEDR SG TERN, 2004) Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” - Carried out by & Study funded by the German Federal Ministry of Transport, Building and Housing Directorate Road Construction, Road Traffic

3. 3 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 Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” -

4. 4 Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” - 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

5. 5 Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” - 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) Defined by National Governments according to functional requirements E- Roads (existing links) Defined by National Governments according to a Grid system of a hierarchical structure Problem:Two Road Network Systems in Europe

6. 6 Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” - 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

7. 7 Preconditions of the method : (1) Study Road Network – graph of the network Functional evaluation of the relevance of the European trunk roads for TERN, taking into account accession countries of Eastern Europe

8. 8 Preconditions of the method: (2) Zoning System Functional evaluation of the relevance of the Euro- pean trunk roads for TERN, taking into account acces- sion countries of Eastern Europe Towards a European Main Road Network Study on combining the TERN/TINA and the E-Road Network based on the Functional Requirements of the TEN-T-Guidelines

13. 13 Summarised Statistics Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” -

14. 14 About 97 % of all links of the existing TERN and E-Road network (average for the complete net­work) 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.

15. 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.

16. 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 Project Group Planning Working Package WP3 - Analysing the existing networks - Analyse the report “Towards a European Main Road Network” -

17. 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.
