The bar chart illustrates the proportion of official investment on transportation infrastructure in four nations between 1990 and 2005.
Overall, it is observable that Portuguese government allocated the most money on roads and transport compared to the remaining countries, while the opposite was true for the UK. Remarkably, the USA was the only state that underwent an upward trend throughout the period.
Upon closer inspection, Italia and Portugal was the two countries that spent most revenue on transportation facilities over the years. The figure for Portugal topped the table in 1990, standing at roughly 27% then decreased gradually to 20% in 2005 but still retained the top position. Italian’s data witnessed a drop of around 7% over the same time frame despite an increase in 2000, the spending of this country followed closely Portugal’s with a mere disparity of about 2%.
Turning to other categories, the British authority didn’t prioritize investing on roads and transportation in comparison with other nations, standing at 10% in 1990 before fell to approximately 7% in 2005. Conversely, despite a modest beginning of around 12%, the data for the USA increased substantially in the final year, reaching the point of precisely 15%.
