Traffic signs or road signs are signs erected at the side of roads to provide information to road users. With traffic volumes increasing over the last eight decades, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to facilitate international travel where language differences would create barriers, and in general to help enhance traffic safety. Such pictorial signs use symbols in place of words and are usually based on international protocols.
From the above illustrated accidents, we can find that there are severe loss due to the accidents.
Therefore we should take correct steps to minimize those.
Especially the all drivers and passengers should obey the road rules and road signs.
On April 26, 1986, the world witnessed the costliest accident in history. The Chernobyl disaster has been called the biggest socio-economic catastrophe in peacetime history. 50% of the area of Ukraine is in some way contaminated. Over 200,000 people had to be evacuated and resettled while 1.7 million people were directly affected by the disaster. The death toll attributed to Chernobyl, including people who died from cancer years later, is estimated at 125,000. The total costs including cleanup, resettlement, and compensation to victims has been estimated to be roughly $200 Billion. The cost of a new steel shelter for the Chernobyl nuclear plant will cost $2 billion alone. The accident was officially attributed to power plant operators who violated plant procedures and were ignorant of the safety requirements needed.
In the end, the total cost of the accident (not including replacement of the shuttle) came out to $13 Billion according to the American Institute of Aeronautics and Astronautics.
