Under the management of road maintenance (MSE) electromechanical equipment systems are increasingly considered important and relevant. Various EMS projects (Equipment Management System) have been conducted or are under construction. It is now generally accepted that a systematic conservation action is necessary and useful to ensure adequate security, and system uptime street. The use of special methods and computer science-aids is well recognised and tested.

The application of this method and aids has, inter alia, aims to identify the economically and operationally optimal time to replace the systems.

The currently used methods, however, often take the "Experience shows expected life" of a plant as a basis. This topic is being researched adequately in various industries and known (eg electricity, industry) sectors, but not in the vicinity of roads or tunnels. Such EM systems have the special property of being widely networked, installed on systems kilometers, consisting of technologically very different parts.
