Résumé / Abstract

This project aims to advance the development and implementation of practical strategies and tools to assist road authorities in optimising the maintenance of their road networks, whilst still addressing the key interests and expectations of road users. ToolBox will develop a concept for proper maintenance planning to assure the selection of adequate maintenance works (schemes or objects) to make effective use of the maintenance budget, based on available road condition data, to give minimal negative effects on road users, safety for road workers and the environment. ToolBox will develop a clear understanding of the concepts applied in the selection of lengths for maintenance (candidates), linked to safety, durability and the environment, including how the data is used combined and weighted within current decision tools and models. Here, ToolBox will not aim to develop new models, but will identify and extract key tools from existing models used in Europe. Also, the work will develop an understanding of how existing knowledge (data) can be used to account for road user expectations in the selection of object lengths for maintenance. ToolBox will then take these existing and new concepts to establish a set of functional triggers for selecting lengths (candidates) for maintenance on the network that include road user expectations and combine them to make recommended prioritised treatment objects. ToolBox will demonstrate the application of the concepts developed within the project via a prototype tool applied to a sample test network, to compare and contrast the approach proposed by the ToolBox tool with the approach proposed by current systems. This report describes how the selected models will be adapted to fit the ToolBox principle. This means specifying the necessary data and finding common base for (at least partner) countries. Since the focus is to develop a working framework.
