Systems Architecture

Our systems are based on a uniform system architecture, applying the 'building blocks' approach. Components from different domains and application areas can easily be plugged together and integrated into a new system.

 

 
 

More than 25 years of our experiences in designing traffic centres have been incorporated into the GeoDyn2® development platform, that enables us to deliver systems with the following characteristics:

  • The use of service oriented architecture (SOA) makes system architectures more robust and improves the reuse of software components through loose coupling of services for flexible and efficient integration as well as strong cohesion of components which allows a sustainable, quality-oriented software maintenance process.
  • Open interfaces on various layers enable development and modification of GeoDyn2® systems through third parties
  • Application Programmer's Interface (API) for direct access to components in different programming languages
  • Web Services based on international standards (SOAP/WSDL, WMS/WFS, CORBA) for an embedding into distributed systems
  • Distributed system with high scalability and data throughput
  • Integrated data management with relational database and data distribution service for data centred software modules
  • Easily modifiable and extensible data model
  • Geo data: Uniform management of geo data including digital maps and supporting various geographical referencing systems
  • Support of various operating systems and database management systems

 

GeoDyn2 – useful tools and features

System monitoring
Automated start-up, monitoring and shutdown of a GeoDyn2® system including all application components Data management Configurable system to  manage all data with automated data distribution ensures real-time capabilities e.g. for alarms and mass data

Data management
Configurable system to manage all data with automated data distribution ensures real-time capabilities e.g. for alarms and mass data


Data base storage
Ensures persistence and makes available all features of relational database management systems, e.g. for transactional integrity

History
Previous configuration states can be reproduced e.g. positions of sensors on sections with modified road layouts

 

Archive
Transparent (re-)archiving system to swap out historic data to external storage

High availability
Hot-standby system via separate primary and secondary system instances that mutually monitor each other and can be switched automatically or manually

On-the-Fly Map Matching

Vehicle-generated traffic data and messages are processed on-the-fly, i.e. independent from a static referencing scheme. This is an essential prerequisite for V2X applications. The data model is designed for both stationary and mobile traffic data.

 

Programmer’s interface
APIs in Java, C++ or SOAP/WSDL to access data, system functions, monitoring functions, geo data management services etc.

Visualisation
Components to visualise digital maps with automatic updates of dynamically changing content

Tools
Tools for system administration and configuration
