The table illustrated the average number of traffic in an urban zone (count in kilometres per hour) and the other table reveal coverage of urban zone in 9 countries between 1970 until now with the future predictionOverall, whereas Italy and Russia show an increasing their traffic during the fifty-year period, France and the USA show a downtrend after 1990 until the rest of the period. Although The USA had risen the urban zone about fourth times from the early period, Rusia only the countries had decreased on urban zone area.
We can see in Table a, if almost two-third of all country had occurred decline in the rest of period (2020est) the rest of country (one third) had gradually increased over fifty years, The most average speed (83) happens in 1970 on France, In contrast, The least of traffic speed (32) occurred in early of a period on Italy. On other tables, almost all of the country had been improved their urban zone areas, moreover, the USA has rapidly increased their urban zones than other 9 countries, In contras, Russia only the country got decreased on urban zones.
