Images of Birds in Yellow Box Junction at the intersection of South Jakarta Duren Tiga, what does it mean?

 

Jakarta - you've crossed the intersection Duren Tiga, South Jakarta? If ever, the road that there is a yellow line with the city-box on the road, which is called yellow box junction. But there are interesting from the line of the yellow box. There is a bird emblem in some box.

 

Actually I have for some time yellow box junction there. Yellow box junction is this line in order to prevent the flow of traffic (Traffic) at the intersection unlocked when the density occurs. Motorists should not pass this line.

Back to the matter of interest, which is the symbol of a bird in the yellow box at the intersection, as currently seen this morning, Wednesday (09/27/2016). It was not known what it means, whether advertising, or mean something, or just a fad.

 

This bird emblem may be reminiscent of the emblem of a transport company. It was not known whether there is a connection or not.

Residents passing motorist and stopped while waiting for the traffic light are also many who do not understand. They do not even know with the bird emblem. I wonder what the meaning of the symbol of the bird, or there is a new emblem in traffic?
