The provided charts illustrate the fluctuations in expenditure on roads and transport across four nations: Italy, Portugal, the UK, and the USA, spanning the period from 1990 to 2005.
A notable trend emerges: a sharp decline in Portugal’s allocation to road and transport infrastructure. Conversely, the USA witnessed a substantial increase over the same period. Italy and the UK exhibited more volatile patterns, with periods of growth and contraction. Furthermore, Portugal emerged as the highest spender, while the UK consistently allocated the least.
Initially, Portugal led the pack, dedicating nearly 27% of its budget to road and transport in 1990. This figure gradually dwindled to 20% by 2005. Italy’s expenditure commenced at approximately 22% and fluctuated between 20% and 24% throughout the period, ultimately settling at around 20% in 2005.
The UK’s trajectory mirrored Italy’s, starting at 10% and experiencing minor fluctuations before a significant surge to 13% in 2000. Subsequently, spending plummeted to approximately 7% by the end of the period. The USA, on the other hand, initiated with a 10% allocation and steadily increased it to a peak of 15% in 2005
