IMESA appeals to municipal engineers to implement stricter road safety interventions in a bid to reduce road fatalities
Worrying statistics recently released by the World Health Organisation (WHO) indicate that the African continent has the highest annual road traffic deaths per 100 000 population in the world.
According to the Global Status Report on Road Safety 2013, a total of 88 countries have reduced their road traffic deaths between 2007 and 2010; however, the global total of 1.24 million deaths per year remains unacceptably high.
If you compare the overall road deaths in Africa, South Africa is not faring well. With an annual total of 31.9 road fatalities per 100 000, South Africa is the second highest killer of road users in Africa, following shortly after Nigeria at 33.7.
Overall, there are large disparities in road traffic death rates between regions and per country income. The African average per 100 000 population is 24.1. The lowest recorded average in the European Union is only 10.3.
The effect of rapid motorisation has put the African continent in disequilibrium, increasing the risk of dying as a result of a road traffic injury.
"The WHO report gives an indication of how serious the issue of road safety is in South Africa,” says Hilton Vorster, a director of traffic engineering at the transport department at the City of Tshwane.
"More disconcerting about the WHO report is the fact that half of all recorded traffic deaths are amongst vulnerable road users: pedestrians, cyclists, and motorcyclists. Progress has been made in high-income countries; however, the greatest need lies with low- and medium income countries where little money is spent and deaths remain unacceptably high,” notes Vorster.
"According to the report, of the 88 countries that improved their road safety statistics,
42 are high-income countries, 41 are middle-income, and only five falls in lowincome
countries.”
Vorster recently flagged these statistics at a branch meeting held by the Institute of
Municipal Engineers of Southern Africa (IMESA) in Pretoria, where he appealed to
the audience - a constituency of IMESA members, predominantly municipal
engineers - to take responsibility for traffic-related injury through improved
engineering intervention.
He imparts that the media often refers to the causes of road deaths in terms of
negligent drivers or non-roadworthy vehicles. "News reports rarely reflect on the
impact of hard engineering elements as a potential cause for road incidents”.
According to the Road Traffic Management Corporation, 85% of accidents occur due
to human factor.
"This statistic may give the impression that we must only focus on the human side of
road safety management, through law enforcement and education; but there is a
serious lack in recognising the importance of safe infrastructure and road
maintenance to prevent accidents.”
Vorster emphasises that traffic engineers should therefore make allowance that will
help compensate for human error. "Roads and roadsides must be built in such a way
that the physical infrastructure, signage and speed control interventions reduce the
risk of road accidents”.
"There are various engineering interventions municipalities can undertake to reduce
road accidents. Through the ‘safe system approach’ roadsides should be built in
such a way that their physical characteristics minimise potential harmful
consequences. It includes speed management measures in road infrastructure
projects, such as the implementation of traffic calming interventions”.
He cites a statistic that a pedestrian has a reasonable chance of survival at an
impact of 30 km/h but as soon as the speed increases to 60 km/h, the chance for
survival becomes less than 20%. Traffic calming measures are of critical importance,
notes Vorster.
"New projects need to be checked to ensure that implementation will meet safety
standards. Already, 140 countries, a total of 77%, carry out some type of road safety
audit on new road infrastructure projects. Existing road infrastructure should also be
assessed for safety at regular intervals, with a focus on roads that have the highest
crash risks,” Vorster informs.
"In 2010, the United Nations General Assembly and governments across the world
declared the years 2011 to 2020 as the Decade of Action for Road Safety. It is imperative that South African municipalities join in to reduce its global road safety statistics, and commit themselves to infrastructure management and road maintenance that will make South African roads a safer place for drivers, cyclists and pedestrians,” says Pieter Myburgh, IMESA’s technical director of roads, transportation and storm water.
"As the Institute of Municipal Engineers of Southern Africa we support our members through advocacy, information sharing and capacity building to improve the conditions of South African roads, through engineering excellence,” he concludes.
