Taxi operators were gathering at Cape Town's Kaisergracht Square on Tuesday for a protest over government's Bus Rapid Transit system.

Police spokesperson Superintendent Andre Traut said taxis were arriving at the square for the legal march.

Earlier, some motorists driving down Du Noon's Potsdam Road were stoned, allegedly by taxi operators.

Traut said Metro Police were closing off some streets in the city as part of preparations for the march.

Local radio station 567 CapeTalk reported that the protesters were upset about the introduction of the government's Bus Rapid Transit system, which they fear will phase taxis out.

They quoted a protester, Surren Taxi Association's Ismail Baradon, as saying that if the transport ministry did not respond to their concerns there would be disruptions during the 2010 Soccer World Cup.

He said that taxi drivers who had hoped to capitalise from transport needs during previous rugby and cricket world cups found that they did not.
