Road Transportation

(a) Advantages of road transportation

1. Door-to-door service and flexibility: Road vehicles can collect passengers and goods from their point of origin and deliver them directly to their destination. They can also use different routes where necessary.
2. Suitable for short distances: It is convenient and relatively economical for moving people, farm produce and light goods over short distances, especially within and between towns.
3. Wide coverage: Roads reach many rural, interior and isolated settlements where rail, air and water transport may not be available. They also complement other modes of transport by carrying goods to and from railway stations, airports and seaports.

(b) Disadvantages of road transportation

1. Limited carrying capacity: Road vehicles generally carry smaller loads than trains and ships; consequently, they are less suitable for very heavy or bulky goods over long distances.
2. Accidents and congestion: Road transport is prone to accidents which cause loss of lives and property. Traffic congestion, particularly in large towns, also delays the movement of people and goods.
3. High maintenance cost and environmental problems: Roads may be damaged by heavy rainfall, flooding and erosion, making repairs expensive. Motor vehicles also produce noise and air pollution.

(c) Contributions of road transportation to development

1. Promotion of trade: Roads link areas of production with markets and consumption centres. They enable raw materials to reach industries and manufactured goods to reach consumers, thereby promoting internal and external trade.
2. Development of agriculture: Good roads enable farmers to obtain inputs such as fertiliser, seedlings and machinery, and allow farm produce, especially perishable produce, to be transported quickly to markets. This encourages commercial farming.
3. Employment and income generation: Road construction and maintenance, vehicle operation, haulage services, repairs and roadside trading provide employment and income to many people. Government also earns revenue through vehicle licences, road taxes and tolls.
4. Opening up and integrating settlements: Roads open up rural and interior areas, encourage the growth of new settlements and towns, facilitate administration, promote tourism and national integration, and improve access to schools, hospitals and other social services.
