Bus Users Shrewsbury will have bus parked at The Cross in the town centre from about 10am until 3pm.
On board will be representatives of the various bus and transport companies that serve the town and the surrounding areas talking in parts of mid Wales and north Shropshire. There will also be a representative from Shrewsbury Council.
Nick Culliford, secretary of Bus Users Shrewsbury, said there were several changes taking place in the area's public transport.
"This is a chance for people to come along, ask questions and find out more about the bus companies' plans for the future."
He thanked Tanat Valley for supply the bus to act as a hub for the day.
