Discussion
▪ Transportation engineering
is the application of technology
and scientific principles to the
planning, functional design,
operation, and management of
facilities for any mode of
transportation in order to provide
for the safe, rapid, comfortable,
convenient, economical, and
environmentally compatible
movement of people and goods.

Four Major Modes of Transportation
4.Airways
z
Road Transport
Advantages:
1.
Provides good commercial link
between cities;
2.
Offers quick and assured deliveries;
3.
Roads can be constructed at
comparatively lower cost;
4.
Offers flexible service, free from
fixed schedules; and
5.
For short halts road transport is the
only economical means.
z
Road Transport
Disadvantages:
1.
Poor record of safety;
2.
One of the major causes of
environmental pollution;
3.
Low carrying capacity of
passengers and goods;
4.
Parking space problems;
and
5.
Consumes greater energy.
z
Railway
Transport
Advantages:
1.
Railway journey is cheap especially
for long distance;
2.
Railways can handle heavier loads at
high speed;
3.
Provides cheap, convenient and safe
mode of transport; and
4.
Easy means of transporting food
and clothes in times of emergencies
such as floods and famines, etc.
z
Railway
Transport
Disadvantages:
1.
Require constant maintenance;
2.
High construction cost;
3.
Tracks are reserved only for the
movement of trains;
4.
Operational Controls
Requirements; and
5.
Suitable for specific service only.
z
Water
Transport
Advantages:
1.
Promotes international trade;
2.
Cost of maintaining and
constructing routes is very low
most of them are naturally made;
3.
Relatively economical mode of
transport for bulky and heavy
goods; and
4.
Safe mode of transport with
respect to occurrence of
accidents
z
Water Transport
Disadvantages:
1.
Longer Lead/delivery times;
2.
Affected by adverse weather
conditions;
3.
Difficult to monitor exact
location of goods in transit;
4.
Customs and Excise
restrictions; and
5.
Could be costly.
z
Air Transport
Advantages:
1.
Fast mode of transport;
2.
Very useful in transporting
goods and passengers to the
areas, which are not
accessible by any other
means;
3.
Convenient mode of
transport during natural
calamities; and
4.
Provides vital support to the
national security and
defense.
z
Air Transport
Disadvantages:
1.
Relatively more expensive mode of
transport;
2.
Not suitable for transporting heavy and
bulky goods;
3.
Affected by adverse weather conditions;
4.
Not suitable for short distance travel; and
5.
In case of accidents, it results in heavy
losses of goods, property and life.
