6 3 Functions 3.1 MS SQL Database The PRIMOS central system can communicate with different databases, preferably MSSQL or MySQL by using ODBC. MSSQL or MySQL are free, object-related database management systems. For database processes, PRIMOS -tools such as Redman 1 Logpack 2, and LZD 6 3 are used. All PRIMOS processes are configured by the database. In the database all system-relevant data (configuration data, traffic data, environmental data and field equipment data) are stored Configuration The following data can be configured in the visualization client and also in the database: Occupancy (parameter traffic density) Predicted speed (parameter speed thresholds) Process control for special programs (conductor / process control) Sign editor Brightness control (parameter brightness values) Parameter weather thresholds Parameter configuration Occupancy Prognosed Speed Conductor / Process Control Conductor / Sign Editor Brightness Control Reaction to Weather Conditions Figure 2: Parameter configuration 1 Redundancy manager 2 Extracts data and stores them in the file system for re-archiving purposes 3 Generates traffic volume data according to German BASt (Federal highway research institute) Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 6/16

7 3.2 System base The system base processes the data exchange and the management between the individual modules. The system base contains the internal monitoring functionalities such as: Process monitoring and - handling Telegram preparation Telegram distribution Process status 3.3 Safety Redundancy Redundant operation systems (virtual machines or physical machines) Redundant processes Redundant database Monitoring The PRIMOS Redman redundancy manager monitoring system is used for monitoring and handling the internal and external programs and processes. Additionally, it handles the: Start and stop Restart of processes Control of the storage spaces and CPU load of the software programs Redman Communication State Watchdog Redman Watch dog Watch dog Processes Services Processes Services Copy DB DB Figure 3: Monitoring Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 7/16

8 3.4 Control processes The control processes contain the different applications. The modular architecture, allows an easy extension of further applications. Line management Conductor process Capacity management Travel time Incident detection Special programs Control Nodes Prognosed congestion Brightness Traffic signals Height control Barriers Figure 4: Control processes Most algorithms comply to BASt 4 standards such as MARZ Supported algorithms: Developed by Swarco Traffic Systems: Speed harmonization Corridor and node management Network-wide rerouting Traffic jam detection Truck metering Ramp metering Overheight vehicle detection Control for hard shoulder running / usage Travel time determination Access control / metering Calculation of visibility, lane classification, slippery road and wind limits Brightness control of signs Environmental data acquisition Customer-specific algorithms based on traffic data, environmental data and weather information can also be supported. 4 BASt: German Federal highway research institute 5 MARZ: Instruction leaflet on furnishing traffic computer centres and sub-centres Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 8/16

9 3.5 Archiving processes All system and processing relevant data are managed within the archiving process. The archiving processes are: Traffic management data VMS data Axle load data Environmental data ANPR data Messages Error messages Operator comments Traffic data Messages VMS swichings Archiviving Comments Axle loads Error messages Environmental data ANPR data Figure 5: Archiving processes Niederkircher Straße 16, D Trier, T , F , E. 9/16

10 3.6 User Administration (administrative processes) In the PRIMOS central system the network administrator can assign access rights for persons and groups (MS open directory). It is also possible to internally assign and administer these access rights. Access rights Operation Read / write Parameterizing Configuration User management Group management User of operating system or internal user Figure 6: User administration 3.7 Message management The message management includes the following report types: System reports of the installation Error messages Operating states Alarms Incidents Facility management Message management Message text bar Popup Other messages Cleaning service Maintenance cycles Figure 7: Message management SMS The message can be prioritized and sent to a defined distribution list.

11 3.8 Events By means of a calendar, events can be planned and retrieved. Special switchings Lane closures e.g. for maintenance works Flexible directional usage of lanes: e.g. for high traffic loads during peak times e.g.at special events such as soccer games, trade fairs Supporting measures e.g. to manage peak time traffic Speed limits for certain time periods e.g. for noise protection at night times e.g.to reduce Ozone values in summer Road works / Mobile road works programs 3.9 Integration of 3 rd party systems It is possible to integrate messages, alarms, streams and information from 3 rd party systems such as: CCTV Barriers Emergency alarms Fire Smoke Emissions Incident detection SCADA (Supervisory Control and Data Acquisition) in order to use the information for traffic management. The PRIMOS central system s data point server allows integrating 3 rd party systems in an easy way by using different interfaces and protocols: WAN-Com (Network connection specifications) Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 11/16

13 4 Visualization The PRIMOS central system is accessed via web browser. The central element of an operator station is the visualization HMI (Human Machine Interface). It represents the interface between the user, the traffic data acquisition system and traffic participants. The visualization displays the traffic situation of the affected area and the currently switched signals. Switching measures, parameterizations and management tasks can be executed and all states of the traffic management system can be displayed. 4.1 Main window The main window consists of a menu bar (left hand side) the status bar (bottom) the message bar (table) the desktop area in which the dialogs are opened Figure 8 Visualization example main window Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 13/16

14 Figure 9 Visualization example dialog Features The system overview of the field side equipment is displayed on a customized map. The user interface displays the status of the field side equipment and allows the operator to monitor and control it. The operation journal archives the operating conditions and the system status. The configuration of the user accounts can be done by an administrator. The switching in between (defined) languages / reading orientations is possible during operation. Automatic pop-ups for alarms or video streams in case of incidents are possible Niederkircher Straße 16, D Trier, T , F , E. interurban@swarco.de 14/16
