WB Report on road safety
As per a World Bank report, published in February 2020, Bangladesh needs to invest an estimated extra $7.8 billion over the next decade to halve its road crash fatalities.
The report attributed the high death rate on Bangladesh roads to a chronic lack of investment in systemic, targeted, and sustained road safety programmes.
The annual road crash deaths per capita in Bangladesh are twice the average rate for high-income countries and five times that of the best-performing countries in the world, it said.
Children and the working-age population were most affected by road crash injuries in Bangladesh, the World Bank report added.
