(Motivated as part of work towards the OSSTIP project)
There are now multiple mature general open source GIS data-serving platforms such as [GeoServer] and [MapServer], as well as capable desktop GIS applications such as Quantum GIS ([qGIS]) and [GRASS GIS]. The excellent [OSGeo] organisation's website maintains a useful listing of these, as well as links to individual projects.
In recent years though, several open source extensions to GIS platforms such as these, and also free-to-access web GIS mapping platforms like Google Maps, have developed to allow analysis and evaluation of the effectiveness of a public transport network.
Many of these allow various forms of Isochronal analysis, to support visual evaluation and communication of the 'geography of mobility and accessibility' provided to public transport users. And notably from a Community Informatics perspective, several of the tools originated or had significant input from civil society non-profit organisations in their development.
The list/table below provides links to several of these projects ...
