Real-time Passenger Information with MARIS

For the S-Bahn area of Munich, we have introduced the highly available information system MARIS. The goal was to significantly improve the quality of passenger information at the 150 stations – with automated, reliable control of displays and speakers, even in the complex interaction of multiple transport providers.

The system processes forecasts, schedule deviations, and train movements in real-time and transmits them automatically, synchronously, and in a targeted manner to passengers.

Our Approach

Automated. Modular. Multi-tenant capable.
MARIS combines deeply integrated data processing with modular software architecture. It incorporates information from various DB systems as well as from external railway undertakings (RUs), calculates operational changes, and updates passenger information network-wide in fractions of a second.

System components overview

Real-time data processing
Utilization of forecast, disposition, and location data from ISTP, LEIDIS, and other systems
Train identification and event control
Automatic detection of train arrivals, platform changes, cancellations, and replacement services
Multimodal display systems
Dynamic presentation via LCD and TFT displays
Acoustic information with CURA®
Live and text-to-speech announcements in various languages, time and event-controlled, configurable by volume and sound quality
User interface for real-time operational interventions
Graphical-topological view of all stations with direct device access
Integrated timetable editor
Editing of regular and special timetables including additional information such as train composition and connecting services

Innovation with foresight

A central algorithm continuously calculates the valid timetable situation for each RU. Even during delays, disruptions, or replacement services, MARIS automatically generates precise forecasts and seamlessly transfers them to display and public address systems.

Predefined reaction patterns (“business transaction forms”) enable quick responses to operational deviations with minimal operational effort and maximum information quality.

Success record

Central control of passenger information at 150 stations
Redundant dual computer system for highest availability
Fully automated control of display and speaker systems
Interface integration for DB systems, external RUs, and planning tools
