A methodology to improve public transport system

The quality of pedestrian routes of access to public transport system (PTS) is an important aspect for the choice of transport mode, that can be evaluated also using some indicators as accessibility, comfort, frequency, etc... The policies for urban sustainable mobility must reflect the design and management of mass transit systems, but also the judgment of users in term of quality and perception of PTS. The purpose is reassess slow mobility encouraging the intermodal mobility between pedestrian and public transport. So the walking can be considered as alternative mode of urban transport and a moment of break from the chaos of modern life. It’s role should be considered as an important element for a new model of structuring the city. Using Geomatics it has developed a methodology for the assessment of accessibility to the PTS, that takes into account the quality of pedestrian path to reach the bus stop. Distance between bus-stops, human energy expended to reach the stops of the PTS etc.. are some elements analyzed in this study. The qualitative and quantitative data of the pedestrian network access have been managed in a Geographic Information System (GIS), proving a valuable tool that can handle a large amount of spatial and heterogeneous data. The results can be of support both at the planning /strategic level that also to the users, if inserted in the context of Web-GIS, making it competitive the integration between pedestrian mobility and PTS.
