Samenvatting
The Institute for Perception-TNO carried out two studies on the categorisation and recognition of roads within built-up areas and on "red-light discipline". These studies are reported in IRRD abstracts 811578, 811596 and 816368. In the report presented here these studies are commented upon. Special emphasis is given to the proposed flashing yellow light traffic signal for pedestrians. Thereafter the problem of cyclists and moped riders neglecting the red traffic signal in combination with traffic coming from the right and having priority is emphasised.
