2. • Accident is defined an unexpeceted , unplanned
occurrence which may involve injury
• Unpremediated event resulting in recognizable damage-
WHO advisory group -1956
• Occurrence in sequence of events which usually produces
uninteded injury, death or property damage
3. Measurement of the problem
Mortality
• Proportional mortality rate:- number of deaths due to
accidents per 100 or 1000 total deaths
• Number of deaths per million population:- killed in a road
traffic accident is defined as any person who was killed
outright or within 30 days as a result of the accident
• Death rate per 1000 or 1 lakh population per year
• Number of fatalities or accidents as a ratio of the number of
vehicles per km or passengers per km
4. Morbidity
• Measured in terms of serious injuries and slight
injuries
• Serious assessed by abbrevated injury scale
• Less reliable – under reporting/ mis-reporting
5. Disability
• May be temperory or poermanent, partial or total
• International classification of impairments
, disabilities and handicaps – WHO- to estimate
disability at a given moment
•
7. RTA
• Ranks first among all fatal accidents
• 1.3 million die per year
• For every death, 20-50non fatal and 10-20 serious injuries
occurs
• Higher in younger age groups
• Children and young people <25 years accounts for 30% of
all injuries and deaths
• males are more prone
8. • In India 4.4 lakh RTA reported in year 2011
• Rate of deaths per 1000 vehicles decreased from 1.6 in
2007 to 1.2 in 2011
• 22.4% were two wheelers
• Maxm number occur between 3-6 pm
10. Speed
• Pedestrains have 90% chance of surving a car crash
at 30 km /hr and < 50% at an impact of 45km/hr or
more
• 30km/hr zones reduces the risk of crash
• Lower average traffic speed
11. Drink-driving
• Risk for crash – when BAC > 0.04gm/dl
• Enforcing check points and random breath testing lead
to reductions in crashes by about 20%
12. Motor cycle helmets
• Wearing helmets reduces risk of deaths to <40% and
severe injury by < 70%
• Helmets should meet recognized safety standerds
13. SEAT BELTS AND CHILD RESTRAINTS
• Seat belts reduces fatality by 40-50% of front seat and
25-75% of rear seat passengers
• Strict laws are effective
• Child restraints are effective fo infats by approx. 70%
deaths and small children 54-80%
