A 20mph speed limit is to be introduced throughout the centre of Oxford in a bid to ease congestion.
Officials say any development would be sympathetic to architecture
Extra traffic calming measures will also improve safety and reduce noise in the city, councillors say.
Bus companies have welcomed the plan, saying they believe it will lead to shorter bus journey times.
Councillors say they want to reassure residents that they will not be installing speed humps, due to sensitivities over city architecture.
Councillor David Robertson said: "Reductions in speeds to this level will make the city centre far more pedestrian friendly. I look forward to the new limits being introduced."
Philip Kirk, the Managing Director of the Oxford Bus Company, said: "Although our drivers will be under strict instruction not to exceed the limit it will not affect our timetable and should in fact lead to smoother traffic flows in the city centre."
