This can be quite tricky. Reading will help and you should always look carefully at the usage whenever you come across it. For example, we say:
We are waiting for the result of the match, and
We are waiting for the result from the match.
In the first case it is simply a time consideration - when the match is finished we will learn the result.
In the second case the match may already have finished and we are waiting until that is received.
In general, however, we use 'result of' something that has or is about to take place (the new road layout and whether or not that improves traffic flow) and 'result from' somewhere about something that is new or has changed (from John in London of the mayoral election).
