The Recent Devastating Crash
Excessive Speeding Incompetence of the driver Poor road and road side conditions
45 children die in Bangladesh road crash
All the factors were involved in the crash:
Overloading The risky vehicle Inattentiveness of the driver
![Page 9: iRap and Road Infrastructure Safety Assessment in Bangladesh](https://reader033.fdocuments.us/reader033/viewer/2022052521/54612d50b1af9f7d228b4746/html5/thumbnails/9.jpg)
Road crashes in Bangladesh kill 4000 and injure 5000 per year.
Actual fatalities could well be 20,038 each year (WHO, 2009).
Death rate of 12.7 deaths per 100,000 population.
Road crashes cost US$2000 million, nearly 2% of GDP.
Bangladesh has a very high fatality rate, over 100 deaths per
10,000 motor vehicles.
The Road Safety Problem
![Page 10: iRap and Road Infrastructure Safety Assessment in Bangladesh](https://reader033.fdocuments.us/reader033/viewer/2022052521/54612d50b1af9f7d228b4746/html5/thumbnails/10.jpg)
About 70% of fatalities in rural areas.
Crashes are highly clustered, 50% of crashes on 5% of highways.
Major crash types are: Hit pedestrian(45%), Rear end (16.5%),
Head on (13.2%) and Loss control/overturning (9.3%).
Almost 80% of fatalities are vulnerable road users (VRUs).
Heavy vehicles, trucks & buses are over-involved.
About 2.5% of accidents on bridges & culverts.

Pedestrians: The Greatest Problem
![Page 17: iRap and Road Infrastructure Safety Assessment in Bangladesh](https://reader033.fdocuments.us/reader033/viewer/2022052521/54612d50b1af9f7d228b4746/html5/thumbnails/17.jpg)
Road Infrastructure Safety: A Priority
Road crashes: interactive factors of the road, the vehicle and
the human.
The greatest potential to prevent road deaths is the road
themselves.
In US, roads are a contributing factor in 53% of all road deaths.
In Sweden, road conditions cause at least 59% of fatal crashes.
In Bangladesh, crash characteristics indicate the problems with
road infrastructure.

iRAP in Bangladesh
iRAP works in partnership with government and non-
government organisations to:
inspect high-risk roads and develop Star Ratings and Safer
Roads Investment Plans.
provide training, technology and support that will build and
sustain national, regional and local capability.
track road safety performance so that funding agencies can
assess the benefits of their investments.

iRAP in Bangladesh
In 2010, with the financial support of the FIA Foundation, the
iRAP Bangladesh Pilot Project began to:
support the Government of Bangladesh and the Roads and
Highways Division (RHD)
support the Bangladesh Road Safety Coalition Project.
provide a practical demonstration of the iRAP approach to
safety.

Possible Countermeasures for N5
Reducing the likelihood and severity of run-off road and head-on crashes by widening shoulders, installing roadside safety barriers and median barriers.
Reducing the likelihood and severity of pedestrian crashes by installing crossing facilities and footpaths.
Reducing risk at intersections through grade separation, roundabouts and traffic signals.
Reducing the risk of all crash types by managing speed to within tolerable limits.

Future Research Work
Further data acquisition and extension of current study.
Preparation of Risk mappings and plotting of Road Protection Score by specific road user groups.
Estimation of number of Deaths using Star Ratings and traffic volume data throughout the road network.
Evaluation of countermeasure options to reduce deaths and injuries.
Selection of Countermeasure options and assessment against affordability and economic effectiveness criteria.

The Way Forward
Bangladesh Government has been a keen supporter and launched the Decade of Action on Road Safety.
Bangladesh looking forward to the goals on reducing 50% of fatalities and serious injuries over 2011-2020.
With the finance of ADB, a new project of assessment of nearly 1500 km of highway is underway.
iRAP provides a strong basis to the development, implementation and monitoring of road safety strategy in Bangladesh throughout the Decade of Action.
