'Vorausgehen' (to precede / go ahead) is a separable verb. In a main clause, the prefix 'voraus' (ahead / in advance) comes at the end. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Der Guide ging der Gruppe im Museum voraus.

The verb is made up of the directional particle 'voraus' (ahead, in advance) and the verb 'gehen' (to go). This structure helps you understand both the spatial and the temporal meaning: something goes or happens before something else.
Bitte geh schon mal voraus und reserviere einen Tisch.
Please go ahead and reserve a table.
The perfect tense of 'vorausgehen' (to precede / go ahead) is always formed with the auxiliary verb 'sein' (to be), since it describes a movement or a process. This applies to both the spatial and the temporal meaning.

He went ahead of us to check the route.
In the temporal meaning, the event that takes place later is in the dative. The sentence structure is often: subject (what happens beforehand) + verb + dative object (what happens afterward).

'folgen' and 'vorausgehen' describe a sequence, but from opposite directions. Spatially, 'folgen' means that someone walks or drives behind a person or thing. 'vorausgehen' means that someone goes ahead. In time, 'folgen' means that something comes afterward. 'vorausgehen' means that something happens beforehand. Learners may confuse the words because both express a sequence. The important thing is the direction you are looking from: 'folgen' means behind or afterward, while 'vorausgehen' means ahead or beforehand.
