Map of the public transport in Pristina.
Lines 1A, 3, 3B, 3C, 4, 7C and 15 are operated by Trafiku Urban, Lines 2, 3A, 5, 6, 7A, 7B, 10A, 10B,... are operated by private companies. Line 1 is shared between Trafiku Urban and Private Companies.

Map supposedly is from 2017, some changes have since been made, but it still is the best tool for orientation on the network.
