Confusing traffic signs

For several months I have been bewildered by traffic signs on the coast road near the junction leading up to ex-Madliena fort, on the opposite side of the former White Rocks complex.

As one approaches this point from High Ridge, the driver is informed that the maximum speed limit is 70 kph. Then he is warned that s/he is approaching a speed camera, and as soon as he reaches this camera the speed limit drops to 60kph.

This I know from experience because the sign is actually facing drivers approaching it from the opposite direction. However, drivers approaching this point from Baħar iċ-Ċagħaq are faced with two speed limit signs. The one on the right is the just mentioned 60kmp one, while the one on the left shows 70kph.

Who is responsible for all this confusion? Why has no action been taken to rectify matters? If the authorities show such disregard for doing things properly, how do they expect road users to behave any better?

Another confusing, and dangerous set of traffic signs have been introduced around the playground as one enters Victoria Gardens in Ta' l-Ibraġ. This playground has always served as a traffic island, and traffic signs have clearly indicated this. However, recently a dead-end offshoot from this point has been surfaced and confusion has reigned ever since. A new sign now permits drivers who want to enter this dead-end offshoot, and the trucks which collect the bring-in recycling containers at this point, to drive straight ahead, in direct confrontation to all the other traffic exiting Victoria Gardens, which has to go around the playground as directed by a "no entry" sign.

For some odd reason, the helpful directional traffic signs on three humped traffic islands have been removed, while the fourth has been turned around, thus creating all this confusion.

For whose benefit has all this been done? Is the perceived convenience of trucks and the users of a very short dead-end offshoot, more important than safety on the road? The retention of the playground as a traffic island will inconvenience no one, while its reintroduction makes sensible traffic management.

Who is responsible for all this? Are the persons entrusted with installing, removing and turning around these signs competent to assume such responsibility? Will they answer this letter and justify their action, or inaction?
