Abstract
Since September 2018, all routes, in principle, of public transport in the Akita prefecture have been included in the transit search of Google Maps. The same process can be easily replicated in other regions. However, a comprehensive map coverage is still lacking due to inadequate understanding of the GTFS format and a dearth of research on the effects of including public transport in transit search of digital maps. With an increase in research on the effects of including public transport in the transit search of digital maps such as Google Maps, and with greater understanding of the GTFS format, it will eventually be possible to achieve complete inclusion of public transport all over Japan in digital maps by 2020.
