Road Safety Analysis For Ipoh - Lumut Highway Using Geographical Information System

The number of accident in sixteen (16) Perak districts is increasing every year. Looking
into the Ipoh - Lumut Highway, there are some places which are prone to accidents. It is
important to pin point which places and/or situations are dangerous, and why they are
dangerous. The objective of the study is to determine the locations prone to accident,
identify the causes of accident and to propose a suitable countermeasure for the problem.
Road Safety Audit (RSA) is a relatively new road engineering technique aimed at
identifying potential safety problems during planning and design of projects. Applied to
existing roads, RSA can identify potential safety hazards before they become accident
prone locations. In road safety analysis apart from producing the most accurate prediction
from statistical figures, the need to visualize information geographically using GIS is
essential. Traffic engineers, planners and decision makers need as much information as
possible in diagnosing the cause of traffic accidents before deciding the appropriate
countermeasure. The scope of study for this report is specifically highlighting the
selection of the location that is prone to accident, the causes that led to the problem and to
propose suitable countermeasure. The project covers for Perak Tengah and Manjung
District which focuses at six prone locations. The GIS is used for road safety diagnosis
involved site characteristics analysis/field observations, accident analysis, accident data
statistics, behavioral observations, surveys of road-users characteristics, and identifying
and recognizing relevant variable. The project is to analyse the pattern in accident prone
location and to prevent more accident to happen.
