Road transport advantages There are numerous advantages of road transport in comparison com parison to other modes of transport. 1. Less capital quality:- Road transport required much m uch less capital investment as compared com pared to other modes of transport such as railways and air transport. 2. Door to door services: - The T he outstanding advantage of road transport is that it provides door to door or warehouse to warehouse services. 3. Services in rural areas:- Road transport is most suited for carrying goods and people to and from rural areas which are not served by rail, water or air transport. 4. Flexible services:- Road transport has a great advantage over other modes of transport for its flexible services. Its routes and timings can be adjusted and changed to individual requirements without much inconvenience. 5. Suitable for short distance:- Delays in transit of gods on account of intermediate i ntermediate loading and handling are avoided. Goods can be loaded direct into a road vehicle and transported straight to their place of destination. 6. Lesser risk of damage in transmit: - Road transport is most suited for transporting delicate goods like chinaware and glassware, which are likely to be damaged in the process of loading and unloading. 7. Rapid speed:- If the goods are to be sent immediately are quickly, motor transport is more suited than the railways or water transport. Water transport is very slow. 8. Saving in packing cost: - As compared to other modes of transport, the process of packing in motor transport is less complicated. Goods transported by m otor transport require less packing or no packing in several cases. 9. Private owned vehicles: - Another advantage of road transport is that big businessmen businessm en can afford to have their own motor vehicles and initiate their own road services to market their products without causing any delay. 10. Feeder to other modes of transport: - The movement of goods beings and ultimately ends by making use of roads. Road and motor transport act as a feeder to the other m odes of transport such as railway, ships and airways.
d i is ad v f r r oad d t t r po or t t va nt ag es of ra ns p In spite of various merits road/motor has some som e serious limitations: 1. Seasonal nature: - Motor transport is not as reliable as rail transport. During rainy or flood season, roads become unfit and unsafe for use. 2. Accidents and breakdown: - There T here are more chances of accidents and breakdown break down in case of motor transport. Thus, motor transport is not as safe as rail transport. 3. Unsuitable for long distance and bulky traffic: - This mode of transport is unsuitable and costly for transporting cheap and bulky gods over long distances. 4. Slow speed: - The speed of motor transport is comparatively slow and limited. 5. Lack of organization: - The road transport is comparatively less organized. More often, it is irregular and undependable. The rates charged for transportation are also unsuitable and unequal.
Ad v Ad f a ai r va nt ag es of rw wa y s High Speed: Air transport is the fastest m ode of transport and therefore suitable carriage of goods over a long distance requiring less time. There is no substitute for air transport when the transport of goods is required urgently.Quick Service: Air transport provides comfortable, efficient and quick transport service. It is regarded as best m ode of transport for transporting perishable goods.No Infrastructure Investment: Air transport does not give emphasis on construction of tracks like railways. As no capital investment in surface track is needed, it is a less costly mode of transport.Easy Access: Air transport is regarded as the only m eans of transport in those areas which are not easily accessible to other modes of transport. It is therefore accessible to all areas regardless the obstruction of land.No Physical Barrier: Air transport is free from physical barriers because it follows the shortest and direct routes where seas, mountains and forests do not obstruct.Natural Route: Aircrafts travels to any place without any natural obstacles or barriers. Because the custom formalities are compiled very quickly. It avoids delay in obtaining clearance.National Defence: It plays a significant role in the national defense of the country

because modern wars are conducted with the help of aero planes. Airways has a upper hand a destroying the enemy in a short period.
Di sad v va nt ag es of ai r rw wa y s . Risky: Air transport is the most risky form of transport because a minor accident may put a substantial loss to the goods, passengers and the crew. The chances of accidents are greater in comparison to other modes of transport.Very Costly: Air t ransport is regarded as the costliest mode of transport. The operating cost of aero-planes are higher and it involves a great deal of expenditure on the construction of aerodromes and aircraft. Because of this reason the fare of air transport are so high that it becomes beyond the reach the common people.Small Carrying Capacity: The aircrafts have small carrying capacity and therefore these are not suitable for carrying bulky and cheaper goods. the load capacity cannot be increased as it is found in case of rails.Unreliable. Most of the air transport are uncertain and the unreliable because these are controlled by weather condition. It is seriously affected by adverse weather conditions. Fog, snow and heavy rain weather may cause cancellation of some flights.Huge Investment: Air transport requires huge investment for construction and maintenance of aerodromes. It also requires trained, experienced and skilled personnel which involves a substantial investment.

Cheapest traffic means Most important in security of nation Plays important role in international trade. Possesses high load carrying capacity. Requires cheap motor powers than for airplanes. Does not require any special infrastructure like roads, and airports. Brings many countries together.

Slow in speed More chances of attack on boat sailing through Only can be used when sufficient water is available. In deep sea if boat gets in to storm, it becomes difficult to rescue. In waterfalls having much drafts ,water transportation does not works. Special maintenance for water tightness of boat is required.
Ad Ad v va nt ag es of r f r ai l lw w a y s trains move massive amounts of "stuff" at one time. trains are the cheapest mode of transporting major amounts of "stuff". trains have massive, industrial strength infrastructures thus lending to industrial ba sed economies. trains are already a form of the new "green" era of tree hugging and energy conservation. trains are economic booms bringing third world countries into first world status. trains are the innovators to more than 25% of all inventions known to mankind.
Di sad v va nt ag es of r f r ai l lw w a y s trains still need trucks to dessiminate some "stuff" to its final destination. trains are not public friendly. trains are limited to land based operations, limited by geography. trains have a very expensive infrastructure. trains are well known for corruption of time, safety, monies and people.
