The image shows several types of transport, both public and personal, lined up on the right edge and facing left, placed vertically, ascending, up being the smallest in size, and below the big and bulky ones.
The vehicles are viewed from side, represented in full relief, and named, from top to bottom, as follows: car, minibus, bus, tram and subway.
At the top there is a man standing, thus positioned to facilitate the comparison of the dimensions of the vehicles to the height of an adult.
The overall picture shows four means of transport, popular in the urban area. In the top right, there is a person standing upright, 170 centimeters tall. Below him is a car that is 40 meters long, about 2 meters wide and 150 centimeters high. It normally accommodates five people.
Under the car, there is a minibus for the transport of a small number of people. The minibus is 8 meters long, 2 meters wide and 3 meters high. It accommodates an average of 16 people.
Under the minibus, there is a bus, equipped for the transport of a larger number of people, being generally used for public, urban or interurban transport. It is 18 meters long, 250 centimeters wide and 3 meters high. It accommodates about 100 people.
Below the image represented by the bus, there is a tram. This is a rail vehicle, composed of several wagons, that runs on tramway trucks along public urban streets and some include segments of segregated right-of way. A wagon is about 30 meters long and 250 centimeters wide. It accommodates up to 300 people.
The last image is a subway, a means of underground transport, consisting of four wagons, rectangular in shape with rounded corners. On average, it accommodates 900 people.
The first bus, a steam engine, was invented in 1830 and went into service in 1895. The inventor of the modern bus and car was the German engineer Karl Benz. The most advanced bus belongs to Gottlieb Daimler.
The first tram in the world was built by John Stephenson on 26 November 1832, in New York City. The first country in Europe where the tram was introduced was France, in 1854. In Romania, the trams were introduced in Bucharest in 1871.
Today, most trams use electrical power, although in the 19th century there were trams using horses. Trams are usually lighter and shorter than trains and subways.
The London Underground is the oldest underground railway system in the world and began operating on 10 January 1863. The Bucharest Metro was opened in 1979. On average, it carries 500,000 passengers daily, from Monday to Friday. Currently, the Bucharest metro network consists of 69 200 meters and has 51 stations. The subways that carry the largest number of passengers annually are those in Tokyo, Moscow and Seoul.
