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.

Transportation plays a vital role in basic infrastructure development in mountainous country like Nepal.

It is a social property.

It is demand fulfilling demand.

3

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 SITEPang Gaun to Tika Bhairav (2.5km)

Location: Zone: Bagmati District: Lalitpur VDC: Pang Gaun

MAP STUDYLocation :- 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

14

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 CONDITIONThe 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.

Principle: Satellites based allocation of a position by latitude, departure and elevation.

Traffic studyA 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 CountA 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.
