shall we see how a junction works from
up high
i've got my special steady camera and a
steady camera means that the picture
will be smooth and steady even when i
put the camera high in the air
oh that is so high
[Music]
look at the junction all the way down
there
can you see the traffic moving up and
down the road
that's because their traffic light is on
green
ah now look the traffic going up and
down has now stopped because their
traffic light has turned red
so now it's the turn of the traffic
going across the junction that means
their light has turned from red to red
and amber and then green away they go
that was brilliant
