Traffic-light signalling and operation to a double red light. Tianjin in the People's Republic of China has two very special systems of traffic lights, in use since : One system is where there is a horizontal bar in a specific colour, with the colour changing and the bar shrinking. The shrinking bar indicates the time remaining in that colour. The colour itself is either red (stop), yellow or green (go). A blinking green one-third-full bar means "reduce speed now", and a blinking yellow full-bar indicates "proceed with caution". When lights of this system turn from green to red, the diminishing green bar will flash
Sinking of the RMS Titanic list to starboard was caused by asymmetrical flooding of the starboard side as water poured down a passageway at the bottom of the ship. When the passageway was fully flooded, the list corrected itself but the ship later began to list to port by up to ten degrees as that side also flooded asymmetrically. "Titanic"s down angle altered fairly rapidly from zero degrees to about four and a half degrees during the first hour after the collision, but the rate at which the ship went down slowed greatly for the second hour, worsening only to about five degrees. This gave
