Standardisierung und Modularisierung verkehrstechnischer Grundprobleme in der Lichtsignalsteuerung

In planning traffic-dependent controls for traffic signal systems repetitive subproblems frequently occur. Solutions which are used again and again in the same or deviating form exist for such subproblems at many planning offices and producers of traffic signal systems. However as a rule these differ considerably in terms of their realization, application width and parameters. Present solutions for subproblems with traffic signal systems are frequently not known generally, are documented in various forms and depth, are too specialized to one certain purpose or characterized highly by the style of the specific manufacturer, so that subsequent modifications by other processors may be difficult. The main objective of this research and development project was therefore to develop primary requirements for definition of the function and description of the treatment of universally applicable software modules for traffic-dependent traffic signal controls, with the intention of creating a basis for solving traffic-related problems with virtual independence from the planner or manufacturer and ensure uniform treatment in the development of traffic signal programs. This research and development project is therefore intended to create the basis for modularization and standardization in order to establish a 'library' with appropriate modules in the future. Analysis of the problems specified showed that a significant step toward a solution would be to differentiate between specification and realization of a module. In contrast to module realization, module specification allows formulation of the function with virtual independence from the planner/manufacturer, thereby allowing potential users a better decision in terms of selection, application or new development of a module.
