Abstract
Nowadays detailed Public Transport (PT) data are available thanks to open standards such as the General Transit Feed Specification (GTFS), introduced to enable information services usually provided via web. In this paper this dataset has been used, after some conversion and filtering operations, for accessibility analysis, based on some indicators to measure how the zones of a city are well connected, in terms of capacity, number of transit options and their efficiency. The study focuses mainly on the assessment of the consequences of transport resources disruption, considering a large flooding event as risk scenario, which could generate also the closure of bridges and then limit the PT coverage. The selected case study is in Torino (Italy), to measure the impact on the various zones of the city, in terms of variation in their transit service accessibility. Relevant capacity reductions (more than 90%) are observed at the north-east of the city.Pubblicazioni consigliate
