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

“Human Error is the main cause of Road Accident in Malaysia”

40% of the road accident were caused by the

following the cars in front closely,

26% were due to dangerous cornering,

13% were due to dangerous overtaking,

12% were due to over speeding!

ROAD ACCIDENTS: HOW

THEY AFFECT US

Page 22: Introduction to road safety

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)

Page 23: Introduction to road safety

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:

Page 24: Introduction to road safety

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

Page 25: Introduction to road safety

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

Page 26: Introduction to road safety

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

Page 27: Introduction to road safety

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.

Page 28: Introduction to road safety

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

Page 29: Introduction to road safety

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

Page 30: Introduction to road safety

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

Page 31: Introduction to road safety

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

Page 32: Introduction to road safety

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.

FATALITY MODEL AND SAFETY TARGET IN MALAYSIA

Radin Umar, 1998

Page 34: Introduction to road safety

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.

Page 40: Introduction to road safety

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

7. Driver Training and Testing

Traffic signs are installed to relay messages about the road system to

all road users. They comprise instructions for the road users to obey,

warnings of hazards which are not self evident, information about

highway route, directions, destinations and points of interest.
