Now, when someone is travelling – because that is the primary context for the expression – are they (is he or she) on transit or in transit? Instead, being on a bus means travelling in it or being part of those doing so. That fellow travelling or moving from one place to the other is ‘in transit’:I couldn’t watch the match because I was in transit. According to Collins Dictionary, if people or things are in transit, they are travelling or being taken from one place to another:They were in transit to Mumbai. For instance, when ‘transit’ means public transportation or a public transportation system like the Lagos’ BRT, one can be said to be on it when patronising it.
