CEDR COTS Team November 10, 2006 Lutz Rittershaus3 Federal Highway Research Institute Germany Cities / Districts Federal States Federal Republic Private Operators (in future) In Germany we have roads in the field of responsibility of: The motorways and federal roads are operated by the road administrations of the federal states on behalf of the federal republic. Already in Germany there are a lot of stakeholders with different requirements in the field of ITS Stakeholders

5. CEDR COTS Team November 10, 2006 Lutz Rittershaus5 Federal Highway Research Institute Germany Starting point in the late 1980s: Technische Lieferbedingungen für Streckenstationen (TLS), (Technical Specifications/Delivery Terms for Outstations) Objective: to open the market for acquiring the equipment to make the equipment of different suppliers compatible, to define features and quality of the components to allow open and easy tendering Standardisation - Inter Urban Roads Current version is the edition 2002, an updated version will be published in 2007 The TLS is applied today not only in Germany. Austria and some eastern European countries are using the TLS too.

6. CEDR COTS Team November 10, 2006 Lutz Rittershaus6 Federal Highway Research Institute Germany Roadside Outstation Traffic Control Centre / Sub-Centre TLS Interface between Outstations and TCCs Technical Specifications for Outstations The basic idea of the TLS is to define functional groups for roadside equipment, to standardise the interfaces and communication protocols, to create a common data modelling.

7. CEDR COTS Team November 10, 2006 Lutz Rittershaus7 Federal Highway Research Institute Germany Guideline:Merkblatt für die Ausstattung von Verkehrsrechnerzentralen und Unterzentralen (MARZ) / Instructions for the Equipment of Traffic Control and Sub Centres Contents and purpose of the MARZ Instructions describe all necessary definitions for sub centres and traffic control centres for federal highways: tasks of the centres, description of the traffic engineering requirements, hard and software requirements, type of data communication between the centres. The intention of the instructions is, to allow the customer to compare the products of different manufacturers and to enable the co-operation of subsystems (hard- and software) from different vendors without complex adaptation to be done. The structures for traffic control centres and sub centres comprise instructions for software and hardware units, the interfaces between them and their relevant common features. On this base guidelines for the design of traffic control centres and sub centres are given, in order to make a co-operating of all components possible. By the modular architecture of the centres, the transfer of software modules between these is enabled without big complexity. Architecture of the Traffic Control Centres

8. CEDR COTS Team November 10, 2006 Lutz Rittershaus8 Federal Highway Research Institute Germany Improving information handling and exchange of road traffic data between centres is an important aspect of ITS deployment in Germany. Actual activities: Some Federal states have already got operational TCCs, a lot more will be established in future. The Federal Ministry of Transport has launched an initiative to define a common, modular architecture for TCC that also covers communication links between different centres. To reduce implementation and operational costs, Easy data exchange between TCCs, because of equal data model and equal communication system, Better quality, because software modules can be developed by different manufacturer (focus on area of expertise), Vendor independence. The current version of all actual documents (in German only), data catalogue, software (published as OpenSource) etc. are available: http://www.bast.de/ -> Fachthemen -> Verkehrsrechnerzentralen des Bundes) Architecture of the Traffic Control Centres

9. CEDR COTS Team November 10, 2006 Lutz Rittershaus9 Federal Highway Research Institute Germany The technical design of traffic management systems for inter urban roads in Germany is based on a series of standards and regulations. These include: Richtlinien für Wechselverkehrszeichen (RWVZ), Edition 1997 (Guidelines for Variable Message Signs) Richtlinien für Wechselverkehrszeichenanlagen (RWVA), Edition 1997 (Guidelines for Variable Message Sign Systems) Richtlinien für die Ausstattung und den Betrieb von Straßentunneln (RABT), Edition 2006 (Guidelines for the Equipment and the Operation of Road Tunnels) Technische Lieferbedingungen für Streckenstationen (TLS), Edition 2002 (Technical Specifications for Outstations) Merkblatt zur Ausstattung von Verkehrsrechnerzentralen und Unterzentralen (MARZ), Edition 1999 (Instructions for the Equipment of Traffic Control Centres and Sub-centres) Hinweise für umsetzbare Stauwarnanlagen (HUS), Edition 1999 (Instructions for Transportable Queue Warning Systems) Vorläufige Hinweise für die Erstellung von Zuflussregelungsanlagen, as at April 2000 (Preliminary Instructions for the Design of Ramp Metering Systems) Standardisation - Inter Urban Roads

10. CEDR COTS Team November 10, 2006 Lutz Rittershaus10 Federal Highway Research Institute Germany Standardisation - Urban Roads Open Traffic Systems City Association OCIT Developer Group Open Communication for Traffic Engineering Components Open Communication Interface for Road Traffic Control Systems OCIT ® OCIT standardisation began 1999 as an initiative between manufacturers and German cities. The OCIT standardisation is going to standardise only interfaces (protocols, functions and data) for traffic light systems. There is no intention to build up standardised units or systems. The OCIT standardisation is pushed by:

11. CEDR COTS Team November 10, 2006 Lutz Rittershaus11 Federal Highway Research Institute Germany The basic OCIT architecture differentiate between this areas: OCIT-Instations, are interfaces of the traffic management system. The aim is to define and to documents standardised open interfaces and data models for traffic control and traffic management systems. The integration of systems and components from different manufacturers and on different system levels will thus be made possible. OCIT-Outstations, are interfaces between the traffic management system (central unit) and field equipment, like traffic controllers, strategic traffic measurement, variable traffic signs and others. Besides this there is the interface OCIT-LED, electrical definitions for LED- signal heads. Standardisation - Urban Roads The OCIT-Outstations is licensed by the ODG. Up to now licenses were assigned to German, Austrian, Swiss, Dutch and Hungarian companies. The OCIT-Instations development is led by the OTEC group. The first fixed version will be published in early 2007.
