The unit of Perugia of CIRIAF (Interuniversity Center of Research on Pollution by Physical Agents), in cooperation with the municipality of Perugia, has started a research project aiming at defining a modus operandi for in-situ measurements able to take into account the characteristics of the site of installation of road marking in order to: ooptimize the maintenance; ogive the municipalities a tool to verify the quality of the application, in order to assess if the requirements given in tenders are fulfilled. The activity is performed within the framework of the EU co-funded project CIVITAS Plus "RENAISSANCE", involving five municipalities of five EU state members. The project aims at testing and developing innovative transport strategies in historic cities (see the website of the project www.civitas.eu). The paper, after the first sections about the state of the art of materials used for road markings and the methodology for the evaluation of their performance, reports the results of a first experimental campaign carried out on several roads of the municipality of Perugia.
