The paper
reviews, road traffic accident data analysis and visualization in R programming
environment. The aim is to show how to extract meaningful data fromthe raw database and visualize it. The results
revealed that hour wise, day wise, month wise and year wise plots allowed
observing how road traffic accidents change in timescale. Two types of road
traffic accident mainly occurred,such as type 1 (collision) and type 5
(collision with pedestrian). Both types of road traffic accidents happened in
similar magnitudes across all timescales. Visualization and data analysis of
road traffic accidents led to make conclusions which would assist reduce the
number of accidents.
