The bar graph compares the government expenditure on road infrastructure and transport across four countries between 1990 and 2005, in five-year intervals.
Overall, the financial allocation rates showed a downward trend in nearly all nations, except for the US, which increased. Additionally, the Portuguese government distributed the highest percentage of budget to road and transport for a majority of the period.
Regarding Italy and the US, the government spending in Portugal initially accounted for the largest share at around 27%, followed by a steady decrease of roughly 3% each 5 years. Conversely, that of the US witnessed a modest growth, rising from closely 11% to 15% from 1990 to 2005.
Concerning the remaining nations, the British authority allocated lowest national budget to road and transport, with only 10% in 1990; although this figure experienced a slight rise in 2000, it then dropped dramatically to about 7% after 5 years. Similarly but to a higher extent, Italy almost followed a comparable trend, decreasing from 18% to 23% during the same period.
