About: Road expansion

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Road expansion refers to the increasing rate at which roads are being constructed globally. Increases in population size and GDP, particularly in developing nations, are the primary drivers of road expansion but transportation planning decisions also play an important role. The anticipated length of newly paved roads to be built between 2010 and 2050 would encircle the planet more than 600 times. Approximately 90% of the new roads are being built in developing nations. Africa and Southeast Asia are predicted to have a large amount of road expansion in the near future.

  • Road expansion refers to the increasing rate at which roads are being constructed globally. Increases in population size and GDP, particularly in developing nations, are the primary drivers of road expansion but transportation planning decisions also play an important role. The anticipated length of newly paved roads to be built between 2010 and 2050 would encircle the planet more than 600 times. Approximately 90% of the new roads are being built in developing nations. Africa and Southeast Asia are predicted to have a large amount of road expansion in the near future. Roads facilitate access to markets, health services and education but may adversely affect the natural environment, and impact communities and economies. There is also disagreement on whether expanding and widening congested roadways truly relieves traffic congestion.. (en)
