Background
 As per our syllabus, we fourth year students have to
present our final year project in our desired field of
interest. It is a vital part of IOE syllabus in order to
make students competent to work in the actual field.
 We have chosen rural road development project
among the number of options available in
transportation project.
 We want to experience the working technique with
new innovative concept of ours while designing a road
in a sense of future demand that is structurally, eco-
friendly and atheistically designed.2

 Transportation plays a vital role in
basic infrastructure development in
mountainous country like Nepal.
 It is a social property.
 It is demand fulfilling demand.

Objectives and Scope
 To setup an alignment of a road as per the
environmental condition.
 To consider gradient, earthwork, road components
(drainage, retaining walls), geometric properties of the
road properly in the design.
 To prepare economical and stable road in rural areas.
 To link urban and rural areas with comfort, wide, safe,
smooth road.
4

Objectives and Scope
 For the overall development of country.
 To minimize the risk of loss of property and lives
by designing stable roads.
 To know the importance of team work.
 To design the road with innovative concept that is
structurally, atheistically and eco-friendly aspect.

ROAD SITE
Pang Gaun to Tika Bhairav (2.5km)
Location:
 Zone: Bagmati
 District: Lalitpur
 VDC: Pang Gaun

MAP STUDY
Location :- Where are things situated?
 A location can be specific for example, it can be
stated as coordinates of longitude and latitude or as a
distance from one place to another place.
eg. In our case, road site’s location is south east from
the valley.
 Latitudes/easting are imaginary lines running parallel
to the Equator.
 Longitudes(departures)/northing are imaginary lines
running parallel to the Prime Meridian.

MAP STUDY

Place :- What makes a place different from other
places? Differences might be defined in terms of
climate, physical features, or the people who live
there and their traditions.
Human-environment interaction :- What are the
relationships among people and places? How
have people changed the environment to better
suit their needs?

SOCIO-ECONOMIC
CONDITION
 The major caste in this area are newars, brahmin,
chhetri, sarkis, etc.
 Mainly the people are involved in agriculture.
 People are not well educated.
 The economic condition is poor.

Traffic study
 A traffic study is an engineering investigation
to evaluate a transportation system.
 A study typically consists of collecting data,
projecting traffic volumes, and identifying the
improvements required for the transportation
system.
20

Traffic Count
 A traffic count is a count of traffic along a
particular road, either done electronically or by
people counting by the side of the road.
 Traffic counts can be used by local councils to
identify which routes are used most, and to either
improve that road or provide an alternative if
there is an excessive amount of traffic.

CONCLUSION
 Geometric analysis of different roads has become
evitable in today’s world. So, we are quite interested
in indulging us in this research as we have interest
towards this subject. Further in Nepal, geometric
analysis of roads are to be done and for this we want
to prepare ourselves.
 We believe that after the completion of this project we
are not only capable of geometrically analyzing
existing as well as newly prepared roads but also can
put forward our suggestions to ensure or increase the
safety, strength and durability of the roads.
