FEASIBILITY studies costing £1.2 million will investigate major transport schemes across the West of England, including in Thornbury and Yate.
Council leaders and metro mayor Tim Bowles agreed the funding at a meeting of the West of England Combined Authority (WECA).
In South Gloucestershire, the two key areas are the A38 corridor and the A4174 Ring Road and Badminton Road (A432) coming south out of Yate.
These two routes comprise the spine of the transport system through and across South Gloucestershire.
The A38 corridor study will include looking at schemes such as extending the Metrobus to Thornbury, building a major cyclepath along the A38 to the town and establishing a park and ride facility somewhere along the route.
It will also consider the re-opening of Charfield railway station and improving the M5 at Junction 14 in Falfield.
The Yate study will investigate projects such as running Metrobus to the town, having better cycle facilities along Badminton Road and introducing a park and ride facility in the Badminton Road area.
Other proposals include improving Yate railway station and building a Winterbourne/Frampton Cotterell bypass.
