New user interface for the traffic management and information centre of ASFINAG

A new user interface component for the traffic management and information centre of ASFINAG has been developed by Heusch/Boesefeldt to manage and activate rerouting strategies. So far large scale detours had to be activated by operators responsible for the regions that were affected by the incident. The centralized concept of operation allowed a direct coordination within the traffic centre in Vienna.In the meantime ASFINAG changed its operational concept and has consigned responsibility for the operation of regional systems to regional traffic centres. Due to this change a fast, nationwide coordination was no longer possible, leading to the introduction of a new role, the national operator. This national operator coordinates and activates the required measures in case of incidents affecting more than one region. The new software provides the required functions to support this new role. Rerouting strategies may be comfortably defined by selecting and adding variable message signs and variable traffic signs to a strategy simply using drag&drop. In order to support a clear presentation of the strategy the affected route and alternative routes may be entered. The routes are then displayed on the map together with all signs belonging to the strategy, using individual colour schemes. The user may choose whether the actual state or the desired state of variable signs should be shown on the map. Using these functions an unlimited number of traffic management strategies may by pre-defined and activated on demand via a single mouse click. The software solely uses a map presentation based on digital map data, thereby avoiding the use of the stylized maps used before which had to be generated with relatively large effort. fileadmin/heuboe/mediapool/news/ARSt2.png The requirement of clearly arranged, non-overlapping presentations of signs on the map has been solved by different means: the user interface provides functions to the user to adapt the presentation to user needs. Changes may be done at any time while the system is running. The position of the signs besides the road may be selected by moving a sign with the mouse to the desired position. Presentation size and orientation of signs may be adapted to different zoom levels, still showing the exact, graphical representation of the sign content. Any setting that has been defined using these features may then be stored for the different network sections as user-defined views, which can be activated later on during operation.
