# GEOMETRIC DESIGN OF HIGHWAY

GEOMETRIC DESIGN OF HIGHWAY

ABSTRACT

Geometric design of highways is an important factor to be considered before highway construction as it necessitates the determination of specific design elements, which include: the number of lanes, lane width, median and width, length of acceleration and deceleration lanes for on and off ramps, need for truck climbing lanes for steep grades, curve radii required for vehicle turning and the alignment required to provide adequate stopping and passing sight distances.  This project work focuses mainly on highway horizontal and vertical alignments which are the most important components of geometric design and intersection. These project works also discusses geometric design of cross section,, sight distance, procedures for highway alignment and the comprehensive plan and profile detailing using manual and automated then comparing the result.

## How To Write Chapter Three Of Your Research Project (Research Methodology)

• Methodology In Research Paper

Chapter three of the research project or the research methodology is another significant part of the research project writing. In developing the chapter three of the research project, you state the purpose of research, research method you wish to adopt, the instruments to be used, where you will collect your data, types of data collection, and how you collected it.

This chapter explains the different methods to be used in the research project. Here you mention the procedures and strategies you will employ in the study such as research design, study design in research, research area (area of the study), the population of the study, etc. You also tell the reader your research design methods, why you chose a particular method, method of analysis, how you planned to analyze your data.

Your methodology should be written in a simple language such that other researchers can follow the method and arrive at the same conclusion or findings.

You can choose a survey design when you want to survey a particular location or behavior by administering instruments such as structured questionnaires, interviews, or experimental; if you intend manipulating some variables.

The purpose of chapter three (research methodology) is to give an experienced investigator enough information to replicate the study. Some supervisors do not understand this and require students to write what is in effect, a textbook.

A research design is used to structure the research and to show how all of the major parts of the research project, including the sample, measures, and methods of assignment, work together to address the central research questions in the study. The chapter three should begin with a paragraph reiterating the purpose of research. It is very important that before choosing design methods try and ask yourself the following questions: Will I generate enough information that will help me to solve the research problem by adopting this method?

Method vs Methodology

I think the most appropriate in methods versus methodology is to think in terms of their inter-connectedness and relationship between both. You should not beging thinking so much about research methods without thinking of developing a research methodology.

Metodologia or methodology is the consideration of your research objectives and the most effective method and approach to meet those objectives. That is to say that methodology in research paper is the first step in planning a research project work.

Example of methodology in research paper, you are attempting to identify the influence of personality on a road accident, you may wish to look at different personality types, you may also look at accident records from the FRSC, you may also wish to look at the personality of drivers that are accident victims, once you adopt this method, you are already doing a survey, and that becomes your metodologia or methodology.

Your methodology should aim to provide you with the information to allow you to come to some conclusions about the personalities that are susceptible to a road accident or those personality types that are likely to have a road accident.

The following subjects may or may not be in the order required by a particular institution of higher education, but all of the subjects constitute a defensible in metodologia or methodology chapter.
