An Overview
 First death in a motor vehicle crashed was in
London 1896.
 Since then, it was estimated 30 millions lives.

6.  1.2 million person are killed annually in road
accidents worldwide
 20 to 50 million person injured annually in road
accident worldwide
 Developing countries 20 – 200 deaths per
10,000 motor vehicles
 Developed countries 2 – 5 deaths per 10,000

ROAD ACCIDENTS: HOW
THEY AFFECT US

22. HUMAN FACTORS include:
 Perceptual Error
- driver or pedestrian looks but fail too see
- distraction or lack of attention
- misjudgement of speed or distance
 Lack of Skill
- inexperience
- lack of jugdement
- wrong action and decision
 Manner of execution
- deficiency in actions (e.g too fast, closed
following etc)
- deficiency in behaviour (e.g reckless,
aggressive, etc)

23.  Impairement
- alcohol, drug
- fatigue, illness, emotional stress
 Adverse Road Design
- unsuitable layout and intersections design
- poor visibility due to layout
 Adverse Environment
- slippery road
- flooded surface
- lack of maintenance
ENVIRONMENTAL FACTORS include:

24.  Inadequate Road Furniture or Marking
- insufficient and/or unclear road signs
- poor street lighting
 Unexpected Obstructions
- roadworks
- parking vehicles
VEHICLE FACTORS include:
 lack of regular maintenance
- defective brakes
- tyre blowouts

25. There are some of the driver errors that lead to motor
vehicle accidents:
• Driving faster than the posted speed limits
• Failing to adjust driving for the road and weather conditions
• Turning left from the far right lane in multi-lane traffic
• Tailgating/ closed following behaviour
• Ignoring Stop, Yield, and other traffic signs
• Rushing through yellow and red traffic lights
• Neglecting to signal before turning

26. Cont’d;
• Talking on a mobile phone when driving
• Punishing other drivers for their driving errors (e.g
immediately changing lane)
• Always using high-beam headlights when approaching
oncoming traffic
• Driving when tired or emotionallly upset
• Avoiding routine car maintenance

27.  Is a structured approach to accident prevention and casualty reduction
both in the urban and rural area.
Road Safety Approach & Strategy
 This may be achieved by the following two approaches:
i) Accident reduction and prevention approaches
ii) Injury reduction approaches
 The accident reduction and prevention approaches involved;
REDUCTION – The application of appropriate road engineering and traffic
management schemes on hazardous location or “blackspot”
PREVENTION – The application of safety principles through road safety
auditing on existing road or new proposed road.

28. The injury reduction approaches involve:
application of appropriate safety policies, vehicle and road engineering,
medical & trauma management.
 These may be achieved by five strategies:
i) exposure control
ii) crash prevention
iii) behavior modification
iv) injury control
v) post-injury management
Road Safety Approach & Strategy

29. Road Safety Management & Strategy
There are at least four basic strategies for accident reduction through the
use of engineering countermeasures.
 Four strategies are:
i) Single site or blackspots treatment
ii) Mass action schemes
iii) Route action plans
iv) Area-wide schemes
Road Safety Approach & Strategy

30. Road Safety Management & Strategy
 Single Site Technique
 Mass Action Schemes
Based on identification of sites with higher than average number of
accidents. These approaches provide a technique for reducing
accidents at high risks sites.
The application of a remedy to locations or areas with a common
accident problem. Some example of these problems with the worst
accident records of wet skidding, on crest hills, pedestrians and
motorcycles.
Road Safety Approach & Strategy

31. Road Safety Management & Strategy
 Route Action Schemes
 Area-Wide Measure
The application of various treatments over a wide area of town/city.
Including traffic management and traffic calming in areas bounded
by links on a network or housing areas having higher accidents.
The application of remedies along a route with a high accident rate.
An example of this initiative is the provision of an exclusive
motorcycle lane along the Federal route F002 between Kuala
Lumpur and Klang.
Road Safety Approach & Strategy

32.  In 1990, The Cabinet Committee of Road Safety was formed to
formulate a national road safety target in reducing road accident
and fatalities. The earlier target was established to monitor the rates
of fatalities due to traffic accident which is commonly defined as
death within 30 days of following an accident per 10,000 vehicles.
NATIONAL ROAD SAFETY TARGET
 An earlier national road safety target was to reduce deaths rate
to 4 traffic accident deaths per 10,000 registered vehicles by the
year 2010. This target was based on the statistical model developed
by Road Safety Research Centre of Universiti Putra Malaysia
which predicted 9,127 deaths in year 2000 if the traffic continued
to increase at the continuing linear growth with 1989 as its base
year.

34. In 2006, the National Road Safety Plan 2006-2010 was launched by
the Prime Minister. This Plan encompasses a total of nine strategies.
Among the strategies are early childhood safety education, electronic
enforcement, safety legislation, road engineering programs and
community based programs.
Strategic Plan for Road Safety 2006-2010
The objectives are to achieve the nation’s road safety goal, as follow:
(i) To reduce 52.4 per cent of deaths per 10,000 vehicles from 4.2 in 2005 to 2.0
in 2010;
(ii) To reduce deaths per 100,000 population from the existing 23 (2005) to 10
deaths;
(iii) To reduce deaths per billion VKT from the current 18 (2005) to 10 deaths.

38. Deaths per 100,000 population in Malaysia

40. In order to objectively address the national safety targets, 15 KPIs were drawn up for the
following sectors:
1. Management of Road Safety
2. Road Accident and Injury Database
3. Road Safety Funding
4. Safe Planning and Design of Roads
5. Improvements to Hazardous Locations
6. Road Safety Education
