INTRODUCTION TO TRANSPORT SYSTEM AND
PLANNING
Economic Front:
It relates population to land use by moving them from one place to
another.
It increases the production by creating demand, easily availability and
reducing prices.
It has vast potential of generating employment.
New markets get developed near production centers.

Planning
deals with selection of projects, defining the problem, gathering and analyzing data, and
evaluating various alternative solutions.
forecast of future traffic; estimate of impact of the facility on land use, the environment, the
community; and determination of the benefits and cost that will result if the project is built.
Design
involves the specification of all features of the transportation system so that will function smoothly,
efficiently, and in accord with physical laws.
used for estimating the facility costs and for carrying out its construction.
Construction
Generally the construction activities include any construction work of the project that has been
defined during the design stage.
Traffic Operation
the elements of the concern are traffic accident analysis, parking, loading, design of terminals
facilities, traffic signs, marking, signals, speed regulation and highway lighting.
Maintenance
involves all work necessary to ensure that the highway system is kept in proper working order.
Transportation Planning:
determination of future goals that is expected from the
transportation system that is expected to be built.
Objectives: to build or improve various parts of transportation
system
includes studies, planning and realization of strategies to supply
the requirement of transport services to meet transport demand.
Transport projects are normally justified for improvement of
traffic flow and safety, saving the travel time and energy
consumption, economic growth and increased accessibility.
involves all the activities required to understand the situation that give
rise to the perceived need for a transportation improvement.
considered which relates trip making to the type of activities that
occur in a region and also to the characteristics of the trip maker that
will influence the way this trips are made.
The type of data on trip maker characteristics include:
Level of income
Number of members in house hold
Number of vehicles in house hold
Age composition of house hold
Education level
Employment etc.
Examples of land use: shopping center, industrial areas, residential
areas, Offices etc…
