Functional related contracts are welcomed by the stakeholders, i.e. road holders and entrepreneurs. Despite this relatively few contracts are initiated or agreed. This paper does not cover the reason for this. Instead it intends to describe that the reason cannot be related to a lack of measuring methods and measures. The paper will discuss and make an overview of existing measuring methods and possible measures that can be used to assess performance of maintenance and operation and accordingly be used as a part to regulate functional contracts. The measuring methods that can be used has to fulfil some basic requirements such as being practical available, be a good enough index covering respective function, sustainable in time and the measures should be able to be related to a reference, meaning that a reference method must exist. The paper will suggest technical parameters that cover required functions and discuss how well it fulfil requirements and finally its status in an European view. The paper will not cover thresholds and pricing questions (A). For the covering abstract of the conference see ITRD E212343.
