This project aims to determine the relationship between road grades and road accident
using GIS. Over the years, there had been numerous researches focus on improving
the safety of road intersection, however there is a lack of research on the straight
section of the road, especially on the grade of the road. Therefore this project will
focus on the safeness of steep road grade on straight roads.
The objective of this project was to determine if there is a relationship between road
accidents and road grades using GIS.
This project is conducted under a GIS environment where sources data are spatially
referenced in the projection of GDA94. Data such as study area boundary, height of a
location and the number of accidents are obtained in this GIS environment. These
information are then used to perform correlation coefficient to determine the
relationship between road grade and road accidents.
The result from the correlation indicates that a relationship does exist between road
grade and road accident. In conclusion this project showed that road with steeper
grade do caused greater number of road crashes when compared to flat or levelled
