On Tuesday the council votes on a motion to set up a new strategic transport authority for the Greater Bristol area.

All political parties are expected to vote for the motion, proposed by Richard Eddy, Conservative Leader.

Bristol Civic Society said: "Bristol needs a real step change in powers over and funding for the local bus network."

Chris Gittins of Bristol Living Streets added: "With growing traffic congestion, rising oil prices and increasing climate change, small changes will not be enough."
