Useless traffic departments

With so many traffic lights out in Johannesburg and surrounds, whether due to load shedding or not, it is absolutely pathetic how very very little there are traffic people out to manage the traffic at these sites. It is disgusting how little the traffic department has responded to these problems. To the extent I personally have seen nasty accidents at one of these traffic sites. What is wrong with the Department? Is this not part of their job. Why do we pay tax for no action???
