Analysing Road Barrier using GIS Software: The Case Study of Bologna

The direct attention of this thesis is the maintenance of road elements to improve road safety. The goal of the research is to prioritise maintenance for barriers based on factors such as the terrain of the site, deformations, degradation of the components, and adherence to the original installation. Using these factors, a coefficient is calculated to determine the maintenance priority for each barrier. To ease understanding and visualisation, data was uploaded and processed in a GIS environment to generate analysis and maps. This was done using GIS, a free and open-source GIS software. Information about the features of the barriers was collected through both on-site and online examination. During on-site inspections, a database of geotagged photos was created to aid in the survey. GIS capabilities word fully utilised by using geoprocessing tools for more in-depth analysis.
