World Main Road Network
Aggregazione dei criteri
Although the world road network appears to be connected, it is more a collection of national networks. The only notable exceptions are Europe where there is a strategy to establish a Trans-European Network (TEN) and North America where the Canadian and American highway systems are well connected. The quality and capacity of the road infrastructure varies substantially which is reflected in transportation costs. For instance, transportation by truck is much cheaper in the United States than in China in spite of lower Chinese labor costs. While a truckload would cost about $1.10 per kilometer to be moved in the United States, it would cost about $1.75 per kilometer to be moved in China.
