Roadways

India has the second largest road network in the world, with around 62.16 lakh km(2020-21). Roadways have developed before railways and continue to be preferred due to their easier construction and maintenance. The increasing significance of road transport compared to rail transport is based on several reasons:

  • Construction costs for roads are significantly lower than for railway lines.
  • Roads can navigate more complex and uneven terrain.
  • Roads can handle steeper slopes, allowing access to mountainous regions like the Himalayas.
  • Road transport is cost-effective for transporting a few people and smaller quantities of goods over short distances.
  • It offers door-to-door service, which reduces loading and unloading costs.
  • Road transport serves as a feeder for other transport modes.
