I’ve been working on adding relations for BMTC bus routes using data from:
mybmtc website: https://www.mybmtc.com
BMTC android app: https://play.google.com/store/apps/details?id=com.bmtc.mybmtc&hl=en.
The android app allows you to track the location of buses and displays a track of the route it took.
A few routes I have added so far:
252F: https://www.openstreetmap.org/relation/6856311
74: https://www.openstreetmap.org/relation/6776481
78A: https://www.openstreetmap.org/relation/6776395
AS-1: https://www.openstreetmap.org/relation/6781293
K-2: https://www.openstreetmap.org/relation/6779593
K-4: https://www.openstreetmap.org/relation/6817995
If anyone wants me to add a specific route or to work on routes for a specific area, I would be happy to do so.
