Commuters abandoned Brisbane's bus network en masse last financial year, with the network carrying nearly one million fewer passengers than the previous year.

Brisbane City Council's 2013-14 annual report, tabled at Tuesday's council meeting, reveals the city's bus fleet carried 2685 less passengers on average per day in 2013-14 than it did in 2012-13.

The figures were revealed on the same day Deputy Mayor Adrian Schrinner announced traffic on the city's road network rose by 3.3 per cent last year, or by 1000 vehicles per day.

But City Hall's public transport chief Peter Matic rebuffed suggestions the drop in patronage was the result of cuts to the bus network last year.
