FACTORS INFLUENCING THE DISTRIBUTION OF MAJOR TRANSPORT NETWORKS IN EAST AFRICA

FACTORS INFLUENCING THE DISTRIBUTION OF MAJOR TRANSPORT NETWORKS IN EAST AFRICA

  • Government policy whereby it can be for political or economic reasons. Areas that are economically viable will encourage government to construct roads and railways to exploit the resources.
  • Regions with abundant economic potential e.g. mining centers tend to have more roads and railway lines compared to unproductive areas.
  • Areas which are urbanized and are densely populated always have more transport routes than sparsely populated areas.
  • Climate whereby areas with heavy rainfall tend to have better roads since they are affected by floods than in areas with dry conditions. However, areas which receive heavy rainfall will also make road construction very difficult due to soft ground.
  • Relief whereby steep areas make road and railway construction very difficult compared to low lands and flat areas which make road construction very easy.
  • Drainage whereby areas with poor drainage e.g. swamps are avoided during road construction while well drained areas e.g. gentle slopes make it easy for road and railway construction.
  • Areas with dense vegetation cover e.g. tropical rain forests will discourage road and railway construction while areas with savannah vegetation will attract road and railway construction. However government will always construct roads leading to forests so as to develop lumbering activities.
  • Areas with water bodies like lakes and rivers will discourage road construction but instead lead to development of water transport.
  • Flat areas also attract construction of airports compared to hilly areas which discourage construction of airports and airfields.
  • Areas with fertile soils will attract large population which leads to construction of roads and railways unlike areas with infertile soils.
  • Areas with tourist attractions will attract roads and airfields to ease movement of tourists unlike areas without major tourist attractions.
  • Availability of capital: where there is enough capital for construction of transport means, government will always develop them than when there is inadequate capital for road construction.
