Just come across this traffic light guess where guys? The traffic light is loaded with all types of information such as the main three types of light (of course), countdown time (guess what it is used for) and road signage. Can you belief that even road signages is displayed together with the main traffic light.
I wonder whether the number of accident will increase or not but one for certain is that users can be distracted from the real purpose of providing the traffic light i.e. to stop when red and to go when green.
Here is another usage of traffic light junctions, also to put on road signages or name of roads.
Traffic light can also be used for cheap advertisement or for directions.
