The given first chart gives data about the average speed of city traffic among the nine countries over a fifty year period. The units are measured in kilometres per hour. The second one predicts for the future about the amount of urban zones in thousands. Overall, it can be seen that we can’t see any correlation between increasing urban zones and average traffic speed.
It can be seen from the first chart that the general trend for speed of traffic is first to increase and then decrease except for four countries. Chile fluctuated around 51kph but remained stable at the end of the period. Italy, Brazil and Spain showed a clear rise, finishing at 58, 57, and 61 kph respectively. The other five countries followed the trend. For example, in France, the speed increased from 60 kph in 1970 to a peak of 86 kph in 1990, forecasting to 52 kph in 2020. Similarly, in the USA, it reached the peak at 57 kph in 1990, decreasing to 43 kph at the end. The UK and Russia had the similar trend, rising to 56 and 72 kph respectively in 2010 before falling to below the starting speed. Also this trend in Canada declined from 69 kph to 64 kph despite reaching a peak of 73 kph.
Regarding urban zones in countries, all countries are willing to increase roughly 4 times by 2020. The expectation is Russia, which sees a fall of about half to 3200.
