VMIS 2.0
Center of the Traffic Management and Information System of the ASFINAG (VMIS) in Austria
The project for the construction of control center of the traffic management and information system version 2 (VMIS2) includes the region wide traffic control (about 800km) and the operation of all tunnel facilities for Austria's trunk roads in the total network of 2,183 km.
The contract is being handled by the consortium EBP AG (Switzerland) - Heusch/Boesefeldt GmbH - evon GmbH (Austria).
Heusch/Boesefeldt was responsible for the development of the software of the core system of the traffic control center and the regional traffic management centers with the realization of the control logic according to MARZ 2018 and the connection of the TLS infrastructure as well as the development of the expert GUI for the management of the evolving versions for the master data and geodata.
In analogy to the existing system, the new traffic engineering core system consists of several regional traffic management centers as well as a superordinate traffic computer center.
The new operator GUI (OP-GUI, realized by project partner evon) provides a uniform modern user interface for operators of all ASFINAG technical facilities that are essential for traffic management. In addition to the operation of the existing outside traffic technology infrastructure, this also includes the operation of the facilities in the tunnels as well as a large number of other systems in the area of traffic management (for example emergency call, event management, videos).
An important aspect when replacing the existing VMIS 1 system was to secure seamless and, as far as possible, uninterrupted migration to the new systems in the sense of uninterrupted operational management. In particular, it had to be ensured that the roadside facilities functioned flawlessly and were managed without interruptions, and that the system's basic traffic engineering services (configuration, parameterization) were guaranteed.
Heusch/Boesefeldt realized the central functions of the system with management of master data incl. configuration of the connected TLS infrastructure and the integration of the digital map on the basis of the Austrian Graph Integration Platform (GIP). This task includes a comfortable versioning and administration functionalities, which can be operated via the so-called expert GUI. With this functionality it is possible for the traffic engineer to manage the different versions on the development, test, integration and productive environments. The expert GUI was developed by Heusch/Boesefeldt as a web GUI.
The basic feature here is the integration of official referencing via route kilometers and route designators on all main lanes and ramps.
For this, the system contains a central geo-service, which is responsible for the conversion between the different references, and a configuration service, which manages plant configurations and other master data. The two services are also used by the traffic engineering algorithms to query asset configuration and route characteristics.
Together with the configuration information provided by configuration service the OP-GUI uses the information of the geo-service for the automatic generation of route overviews and network overviews.
The system collects all available data and information from the connected facilities and recording systems and transmits them to the connected central data storage of ASFINAG.
All specifications of the system have been developed in compliance with the German regulations, in particular the MARZ (specification for the hardware and software equipment of computer centers) in the latest version 2018 as well as the TLS (technical specifications for outstations).
Since the opening of the traffic center and the first regional traffic management center in Vienna in Dec 2021, the consortium provides maintenance and service around the clock (24/7/365) with a guaranteed availability of at least > 99%. This high availability is achieved by a geo-redundant OKD cluster for the regional traffic management center (rVMZ) systems and the traffic computer center.
