The use of the methodology “Road Safety Review” in the road safety analysis has been spread for a long time.

Abstract

The use of the methodology “Road Safety Review” in the road safety analysis has been spread for a long time. These methodologies are used to analyze in detail the different components of the streets and to see which are the elements that affect adversely the road safety. Checklists are drawn up in form of technical questionnaire and classified by topic, each in turn divided by sub-topic. It’s clear that topics to be considered depend on the element to be analyzed, whether it is an arc or a node. Indeed, checklists are divided in two main macro areas, one for the arcs analysis and the other for the nodes analysis. In this way, it is possible to study in detail each part of the road network and identify the most critical areas. It is important to carry out on-visits in any arc and node, as well as to draw up the checklists. Once completed, a large number of data is available, but they are often difficult to be read. In this study, we wanted to develop a management system checklist more fluid and functional, whose main goal is to have an immediate overview of the network situation under consideration. The summary procedure can be resumed through the drawing up of the checklist with the answers “yes”, “no”, “in part”, “n.a”, giving to each answer a score - according to its influence on the road safety; calculating a weighted average for each subcategory and finally, for each category. The result of this analysis is then managed on a GIS platform and represented in graphics. In this way, it is possible to have in real time an overview of the entire network under consideration. In this way, it will be possible to create a more efficient and manageable use of the checklists.
