A plan to cut hundreds of bus services on key routes in Melbourne's west and north has been dumped by the Andrews government.

The changes, proposed last year by bus operator Transdev, would have taken 433 weekly bus services away from routes in the city's west and north, a cut of more than 20 per cent, to add capacity to popular routes in the outer east.

Some western suburbs routes would have switched from 15-minute frequencies to a bus every half-hour.

But Public Transport Minister Jacinta Allan announced on Tuesday that Transdev's proposal would not proceed, after a report in The Age that outlined the impact of the planned cuts.

"Demand for buses is growing faster than any other mode of transport, and we need to make sure they continue to meet the needs of our community," Ms Allan said in a statement.
