1. WG on Statistical Confidentiality (TRansport Information System)
TRIS
(TRansport Information System)
TRIS 1 / TRIS 2
Nico Hilbert

2. TRIS 1
What is TRIS? TRIS is an Information System (IS) framework
What is TRIS doing? It implements & integrates under TRIS 1 the today’s Transport IT systems as sub-systems:
The legal transport modes’ data collections
(Aviation, Inland Waterways, Maritime, Rail, Road Freight)
The voluntary data collections
(Regional, Common Questionnaire)
Indicators
(newly developed from an EXCEL desktop application)

3. TRIS 1 What was the objective of TRIS 1?
Implement / integrate / harmonise / document the today’s Transport IT systems with only minor changes into TRIS sub-systems
Enable the Transport IT systems to interface with the Directorate B developed IT/IS systems and services, use its components and building blocks
Enable VISION compliance

4. TRIS 2
What is TRIS 2 doing?
It will implement & integrate as TRIS 2 sub- systems also the future Transport IT systems like:
Aviation air emissions
(an extension of the Aviation transport mode TRIS sub-
system merging statistical data with other data sources)
Road traffic
(first as voluntary data collection later as a legal data
collection)
Transport Safety
(as a voluntary data collection by and from the transport
safety agencies )

5. TRIS 2 What is the objective of TRIS 2?
Implement a cooperative validation environment with
Member Countries in the standard and secured IT
environments in EUROSTAT
Enable the Transport IT systems to interface with the new Directorate B developed IT/IS systems, services, components, tools and building blocks converging to and complying with the VISION
With TRIS 2 (and future versions of TRIS) continue implementing the VISION as of the availability of the items here before

6. TRIS 1 & TRIS 2
TRIS is implemented in the EUROSTAT standard and secured IT environments
2 legal transport modes (Aviation, Inland Waterways),
2 voluntary data collections (Regional, Common
Questionnaire) and Indicators are implemented under TRIS
in the standard EUROSTAT IT environment
3 legal transport modes (Maritime, Rail, Road Freight)
are implemented under TRIS in the secured EUROSTAT IT
environment
TRIS has an IS architecture based on the state of the art n-tier thin client / server model

TRIS 1 / 2 Architecture TRIS Information System Architecture based on the n-Tier Thin Client/Server Model
Thin Client
typically a Web-Browser like MS Internet Explorer on a PC
PC Client launching a request to the Web Server
eDAMIS
Web Server
Web Server
If the Web Server cannot satisfy the request from the PC Client
it is becoming itself a Client launching a request to the
Application Server

Application Server
+ eVE (TRIS 2)
Application Server
ECAS Server
BO Server (TRIS 1)
If the Application Server cannot satisfy the request from the Web Server, it is becoming itself a Client launching a request to another Application Server or to the Database or to the Authentication Servers

8. TRIS
Data Management of the TRIS sub-systems are sub-contracted and are executed as follows:
From the premises of the sub-contractor outside EUROSTAT for those transport modes processing non-confidential statistical data in the standard IT environment (Aviation and Inland Waterways)
From the secured data rooms inside EUROSTAT for those transport modes processing confidential statistical data in the secured IT environment (Maritime, Rail and Road Freight)

10. TRIS 2 Architecture extension
Waiting for new extended network architecture implementation stemming from the network architecture to be implemented for the access for researchers from secured data rooms in the NSIs
TRIS – eDAMIS data confidentiality issues in reports
No or limited values to be included in the reports
Reported errors must mostly be related to the record numbers + record key identifier in the MSs input dataset received via eDAMIS
