Comfort Index CI(bus): A methodology to measure the comfort on board

The presented work deals with the important topic of assessing the quality of public transport services. This research specifically addresses the performance of the service in terms of comfort. In particular, the study focuses on the definition of a comfort index (CI) that takes into account two dimensions (noise and vibration) measured on board the buses studied, both during motion and on a stationary vehicle. The methodology interprets how users perceive the comfort on board the public transport considered, with numerical data coming from high-precision measuring instruments. This methodology represents a further element of synthesis in the complex quantification of perceptions by an individual, precisely because of the extreme subjectivity of judgment.
