Attending conferences and
making presentations at them is a key way to becoming
established on the world road safety scene. It is very
enlightening too to be able to see at first hand what the
problems are in a particular place. It seems for example that
the new capital of Nigeria, Abuja, was designed to operate
with traffic signals at all key at-grade intersections.
However, it became apparent that the electricity supply was
not reliable enough for this and many signals are permanently
"out" as their systems have failed with repeated
power failures and surges.
The modern roundabout does not appear to have
arrived in many countries in the world and this is a great
shame because it is now the proven tool for safe intersection
control in the vast majority of cases. And a key point in
favour of roundabouts is that they continue to operate in
almost all conditions whether or not there is an electricity
supply and in extreme weather conditions.
