osing the lives of our family members due
to road accidents is an experience no one
would ever want to live with, more so when
we know that it could have been prevented. The
aims of road risk management include protecting
users from being exposed to hazards, minimizing
the severity of injuries in the event of a crash, as
well as safeguarding owners against legal action.
Many developed countries are now championing
the Safe Systems approach, a road safety concept
which acknowledges that humans do make
mistakes but should not deserve to die from road
accidents [1].
Road Assessment Programmes (RAPs) have
been in existence since the early 2000s in a
few developed countries in Europe, Australia,
New Zealand and the United States where new
inspection methodologies have been adopted
[2]. Consequently, many low and middle income
countries are now implementing RAPs where
low cost countermeasure programmes are being
identified and implemented. An inspection system
consisting of vehicle survey and data coding
software is required to collect and analyse road
inventory data.

Research (MIROS) in collaboration with Universiti

Technology Sdn Bhd has developed a road survey
system called the Road Attribute Data Logger
& Inspection System (RADIS). RADIS is a data
collection system consisting of video recording
and data processing systems which can be divided
into four sub-systems as follows:
1. A video recording system consisting of a
Graphical User Interface (GUI) for video
imaging and GPS coordinate capture,
display and record.
2. A client and server based GPS coordinates
streaming system.
3. A calibration system of the image for road
width measurement.
4. A system to measure road geometric
parameters.
The first two systems are designed to
capture and process high-definition images
along with respective GPS data while the third
and fourth systems were developed with the
necessary function of viewing and measuring
road attributes. Besides incorporating on-screen
measuring capability, the system is also designed
to collect and process road gradient and radius of
curvature data to aid in assessment activity. With
these, the element of subjectivity in assessment
is eliminated, thus maintaining consistent
assessment results from different people.
