While there are few in-car navigation systems, majority of Indians still travel by bus and the irony is that there are very few places online to get the bus routes.
BusBus is addressing this challenge for Chennai, Mumbai and Bangalore. Once you enter your search query (auto-suggest implemented), BusBus flushes out bus routes available – one can filter results by alighting points ).
Busbus is integrated with Google maps (click on bus name and get the detailed route on maps).
The product surely looks interesting (it takes sometime to understand the UI though), however there are couple of features missing in the current avatar – significant ones being bus timings and frequency of arrival/departure.
If you are from Bangalore, Mumbai or Chennai, do give BusBus a ride and share your feedback.
