The tables show (Table a) the average speed of urban zone traffic (in kilometres per hour or kph) in a number of countries over a fifty-year period, including a future estimate; and also (Table b) the total number of urban zones per country (in thousands).

On one hand, the first table illustrates the mean speed in urban boundaries from 1970 to 2020 in different states of the world.

On the other hand

, The second chart represents the evolution of the total number of urban surfaces per territory. Both sheets are measured respectively in kilometres per hour and in thousands.

Overall

, some countries will drive faster in 2020 than in the 70s

whereas

other players will drive slower than before. Looking into constructed zones, I can observe two different trends. The vast majority of territories have expanded their built surfaces in a period of 50 years.

number goes from 6.7 thousand to 3.2 thousand compared to its peers who multiply that amount between 3 and 5-fold. When it comes to speed average, France, the USA and the UK could see an impressive drop from 1970 to 2020.

Although

the fall is not that huge, some of them could experience a 20% drop in the numbers. As opposed to those declined countries, others acknowledge a rise in

For example

Furthermore
