一開始我也搞不清，這種票是單程的，不讓回頭。90分鍾內可以轉多次，隻要朝一個目的走就行。官網上說：
”How do I use a t+ ticket on buses and trams?
You must always validate your t+ ticket when you board a bus or tram. Once validated, your t+ ticket allows you to make as many transfers as you want to other bus and tramway lines for 90 minutes (between the first and last validation). Each time you change buses or trams, you must validate your t+ ticket again.
Note: the same t+ ticket cannot be used for round-trip travel on the same bus line, or for two trips in the same direction on the same bus line (i.e. you get off a bus and later take another bus on the same bus line).“
