Transport bosses in the south-east and south of England are proposing £800m spending on roads and public transport.
The South East England Regional Transport Board has approved new plans for the five-year period from 2011, and will now seek government acceptance.
Work would take place at Reading and Oxford railway stations, and new bus schemes are planned along the Sussex coast and around Ashford in Kent.
The Thames Valley area, west of London, would get a new bus and coach network.
The board works on transport improvements as part of the 20-year South East Plan.
Its advice on transport priorities for the five years leading up to 2011 were ratified by the government in July.
"We hope we will receive an equally positive outcome for this programme," said Councillor Nick Skellett, chairman of the transport board.
Ten of the 16 schemes proposed for 2011 to 2016 involve public transport.
They include park-and-ride facilities in Windsor and High Wycombe, four new platforms at Reading railway station, and improvements at Oxford station and on the line between Didcot and Bicester.
Bus priority measures are planned on the A3024 to Southampton; a Coastal Expressway bus service will link Brighton and Hove with Portsmouth; and Smartlink buses will provide access to Ashford town centre and the international railway station.
Road schemes include better access into Oxford on the A34 and A44; improvements to the A27 Chichester bypass in West Sussex; and work on the A421 from Milton Keynes to the M1.
