STRATEGIC	2	2	I	--	Strategic network   0 = No link of Strategic network   1 = Strategic network

Notes:

Country indicates the ISO-Code of the country in which the link is located. Because rail ferries cannot be assigned to any one country, rail passenger ferry links have the country code 'YY'.

LINKTYPE, LINKCAT and LINKUSE give general information on links. TENCAT, TENALIGN, CATEGORY and PRIORITY indicate the inclusion of the specified link in the TEN and TINA programmes according to European Commission (1996) and TINA Secretariat (1999). Information on those links which are included in the "Trans European Transport Network Outline Plan, Section Rail" are taken from the 'Joint Decision of the European Parliament and of the Council' published in the Official Journal of the European Communities (L228, 9 September 1996). Information on those links which are included in the TINA networks are taken from "TINA Transport Infrastructure needs Assessment. Identification of the Network Components for a Future trans-European Transport Network in Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia" (TINA Secretariat 1999) as agreed between the European Union and the candidate countries. PRIORITY represents the "specific" projects adopted in 1996 ( so called "Essen list") and potential "specific" projects as defined by the European Parlament and the council in 2001.

STRATEGIC indicates whether the link is part of the strategic rail network. The strategic rail network is a subset of the total network used in the DGVII projects STREAMS, SASI and STEMM. The strategic rail network contains the trans-European rail links specified in Decision 1692/96/EC of the European Parliament and of the Council for the EU member states, the TINA networks as agreed between the European Union and the candidate countries, the ,Helsinki' corridors towards eastern Europe as well as selected additional links in eastern Europe and further links to guarantee connectivity of regions and centroids.

The access links are functional links used for transport modelling to connect centroids to the network. Centroids represent the centers of transport modelling zones and are used as their origins and destinations. Each centroid is connected to the real-word network via one or several access links. If transport models are not to be applied, the access links (and so the centroid nodes) can be dropped from the network without harming the overall network as such.

The following table shows the contents of the Node Attribute Table:

Item	Width	Output	Type	Dec.	Contents
ARC#	4	5	B	--	--
RAIL#	4	5	B	--	--
RAIL-ID	4	5	B	--	--
NODETYPE	3	3	I	--	Node type   0 = Centroid   1 = Border node (see note)   2 = Rail node   3 = Rail ferry seaport   4 = Rail bifurcation/intersection
NODEID1	10	10	N	4	Node-ID xxx.yyyy   xxx = Region-ID (see note)   yyyy = Node number   0000 = Centroid   0001 ... Node number in region
COUNTRY1	4	4	C	--	ISO country code (see note)
REGION1	4	4	C	--	Region code (see note)
NODEID2	10	10	N	4	Node-ID xxx.yyyy
COUNTRY2	4	4	C	--	ISO country code
REGION2	4	4	C	--	Region code (see note)

Notes:

NODEID1 is a unique number for each node in the network. The first three digits indicate the number of the region in which the node is located. COUNTRY1 indicates the ISO code of the country in which the node is located. REGION1 is a four-character acronym of the name of the region.

The regions are regions of the system of regions defined for the STREAMS and SASI projects. They correspond largely to NUTS-2 regions defined by Eurostat plus equivalent extensions outside the European Union. A more detailed description of the system of regions is available.

The main city (not neccessarily the greatest city) of each region is the centroid of the region. For each region the nodes are counted from 0000, with 0000 indicating the centroid.

Border nodes are nodes at national borders. At each border crossing there is a border node. Border nodes have two node numbers, country codes and region codes indicating that the border node belongs to two countries. Regular nodes have no entries in NODEID2, COUNTRY2 and REGION2.
