The issue of overcrowding is expected to remain as one of
the major issues that persist in transport geography. With the anticipated
demand may have a significant impact on the nature and form of future
transportation industry. In the short term at least, the road transport
industry is expected to continue dominance of transport.
There are two basic
reasons for this claim. In the developed world have mastered the car and truck
market, and patterns of living of the people, industry and services have
adjusted themselves rather to demand this mode.
(a) Low density
The broad pattern
of pushing space traffic congestion is getting more out, and make it extremely
difficult for higher capacity modes other than competition. At the same time
the demand for mobility is growing as a result of rapid industrialization in
developing countries such as China and India. There are also changes taking
place in the capital in favor of road transport. Increase well-being in these
countries is a huge potential for growth in road transport.
(b) Congestion is a phenomenon bound space
It occurs in
certain locations that have an impact on a variety of scales, from the
intersection of highways that may slow down traffic over several hundred meters, blocked the port that can disrupt the flow of goods more than half of the
continent. Each event is the reaction chamber, the car driver who seek out an
alternative route to the sender choose a different mode or point of entry for
successful delivery. Increased demand and increased likelihoods congestion will
increase new answer space and therefore it seems very likely that the new flow
structure and space to exist.
(c) Demand management
With respect to the conditions and in
what type of location can move modified request. In the context of the market,
when the supply of permanent and increasing demand, price adjustment on the
inevitable happen. However, much transportation infrastructure, such as
roads, are provided free of charge, reflecting the cost changes, increased
congestion levels. Thus, there is a growing need to provide incentives and
re-evaluate priorities in the use of infrastructure, particularly in urban
areas.
Already there is evidence of air transportation for
passengers and cargo growth in the number of smaller airports.
(a) Economic and
social impact
In a context where more simultaneous transport network
congestion can create a multiplier effect not only affects the cost, but also
the reliability of the transportation system. Economic and social impact of
congestion continues to be a major issue, especially in developing countries
where it can hinder economic growth.
(b) Passengers than freight
Congestion also raised the issue of
priority transport passengers than when they share transport infrastructure or
when activities such as terminal or cargo distribution center is located in
proximity to the location where the public transit passengers. This requires a
careful assessment of the cost of each particular passenger congestion and
freight transport system and in which circumstances impose the external
congestion. A key issue concerns how the distribution of goods can be better
integrated in the urban environment in which the movement of passengers tend to
dominate city logistics field .
