The VEDENS Visual Display
The visual display is divided into ten segments, with each vehicle progressing
through them as it moves along the road.
The visual effect
is akin to that which would be obtained from ten observers, each suspended in
a balloon above a stretch of highway, each transmitting a picture back to a central
control monitor. Vehicles enter at the bottom left and proceed along the bottom
segment, then the second, etc., until they leave at the top right. The display
indicates driving on the right, but this is not implicit in the model; driving
on the left is simply a mirror image. The coloured edges of the road indicate
the speed limit in force and are dotted for uphill gradients and dashed for downhill
gradients. The colour of the vehicles varies from dark blue for very slow speeds
to orange for faster moving vehicles. Brake lights are indicated by red at the
rear of the vehicles.
