The bar graph compares how the distribution of government financial allocation to road and transport varied across four nations between 1990 and 2005, at 5-year intervals.
Overall, the government fiscal support for road and transport witnessed a downward trajectory in the majority of countries, except for the USA, where its funding rose. Additionally, among the four surveyed countries, Portugal stood out as the primary one with the highest financial allocation throughout most years.
The USA was the only nation to widen its funding assistance for road and transport. Holding the third position in 1990 at slightly over a tenth, the government expense decreased minimally to precisely 10% 5 years later. However, it diverged from the downward trend seen elsewhere, mounting a notable recovery that had lifted its figure to precisely 15% by the end of the period.
In contrast, a more pronounced fall in the percentage of government expenditure on this sector was recorded in other nations. This decline was particularly noticeable with Portugal, which was also the leading country with approximately 27% of monetary allocation initially, but then it plummeted to exactly 20% in 2005. Consequently, the gap between the leading nation and trailing ones narrowed, making Italy secure the top position at roughly 23% in 2000, albeit with its short-lived peak, decreasing to close to 20% in the final year. Finally, the figure for the UK was comparatively low, no more than 10% in most years with an exception of 2000, when it reach the highest point of 12%.
