“Delhi Public Transport app makes the direction and time-table information for Delhi Metro and buses available offline, to help users get information about directions between bus stops and metro routes even when they don’t have any net connection,” Google said in a statement. “Once the app is downloaded, it uses no data for directions’ queries or timetables, even if the phone is online. A small amount of data is used for news alerts (if online, roughly 1 KB each, about once a day) and user-optional feedback (up to 100 KB per feedback report),” it added.
The app will use the same transit data for DMRC metro, DTC buses, DIMTS (orange) buses and Gurgaon Rapid Metro as that found on Google Maps and available offline for the users. According to Google, around 2.6 million people travel by Delhi Metro.
