Police and public members are lacking statistical skill to interpret accident data

Police and many public members only look at a single point or a few data points to conclude Ops Sikap is success or failure.

The head of traffic safety department in JPJ said there is improvement during this operation by comparing average death number against last six months data while our public members compared this year Ops data with previous year, and concluded more deaths per day.

Both JPJ/police and public members are wrong in data interpretation. Singapore police was doing same thing as our police several years ago.

Dr. Deming described this problem is due to lack of profound knowledge in statistics.

In order to see road accident is improving or worsening, we have to use statistical process control technique to analyze its trend over time and to see the trend is within the statistical control or not.

All actions taken by our police and JPJ in combating road accident are like a dog chasing its tail, have never achieved their intended goals.

More police personnel on the road during festival season is like a quick-fix solution, the root causes of high accident rate are still NOT proper identified and addressed.

Dr. Deming also said permanent solution for any problem only can be achieved through reduction in the system variation (or root causes).

Vision 2020 can be achieved only with profound knowledge attained in every sector amongst our people.

MAILBOX: Ops Sikap XX already showing signs of becoming another failure

TRAGEDY: More needs to be done to prevent road accidents
OPS SIKAP XX is showing signs of failure again, with a total of 160 deaths recorded as at Sept 22 – even before it ends on Sept 27 – with 26 more deaths, when compared with figures for same period last year (click here for figures).

Looking at statistics given by the traffic police each year – past and present – despite the Ops Sikap operations and road safety campaigns carried out nationwide, the fatality rate remains high.

What is really alarming and shocking is that motorcyclists continue to be the highest fatalities.

It certainly warrants the authorities taking up immediate and concrete actions to help save the lives of motorcyclists during next balik kampung exodus.

Why don’t the traffic police and the Road Transport Department make it mandatory for all motorcyclists to stay away from riding on expressways, highways and toll roads, except where there are lanes allocated for bikers, during this exodus?

Getting motorcyclists to use only the emergency lanes on highways and federal roads, where there are no lanes designated for bikers, during such periods – to help cut down on the rate of motorbike accidents – is indeed the right thing to do.

Further, keeping trucks and heavy vehicles to stay off these roads as well, during the operations and campaigns, was the right move.

Traffic policemen deployed to work at hotspots should be stationed in the open by the roadside, say 500m before the danger zone, to guide or slow down the traffic before motorists reach the area.

With correct guidance, education and help from the traffic policemen on the roads during any Ops Sikap campaign, motorists and bikers will get to reach home safely .

No matter what, the bottomline is to save lives. We don’t want to see anymore fatal road accidents during balik kampung exodus on our expressways, highways and toll roads.

Let’s practise a give-and-take attitude once we are behind the steering wheel and ensure that courtesy is also our way of life.
