BEHAVIOUR AT SPEED IN RESIDENTIAL AREAS UNDER DIFFERENT REGULATIONS FOR PERMISSIBLE MAXIMUM SPEED: KAP: THE INFLUENCE OF TRANSVERSE MARKINGS ON THE BEHAVIOUR OF LORRY DRIVERS - "OPTICAL BRAKE"

GESCHWINDIGKEITSVERHALTEN IN WOHNGEBIETEN BEI UNTERSCHIEDLICHER REGELUNG DER ZULAESSIGEN HOECHSTGESCHWINDIGKEIT; KAP.: DER EINFLUSS VON QUERMARKIERUNGEN AUF DAS FAHRVERHALTEN DER KRAFTFAHRER "OPTISCHE BREMSE"

As a result of the monotony during long journeys at the same speed level or with minor changes in alignments a reduction in attentiveness threshold can lead to the driver no longer consciously registering road signs. At places where too high approach speeds for this reason cannot be sufficiently reduced by road signs, motivation for deceleration can be provided by the so-called optical brake. For this purpose transverse markings are made on the road at decreasing distances apart depending on the local and dynamic-driving relationships. For a deceleration of a desired amount the lines are at a constant spacing, a lower deceleration gives the impression of an apparent acceleration. Practical tests on the end of a motorway at an access ramp and at the approach to a crossing showed that with proper application the optical brake can produce the intended effect of a change in speed by properly timed deceleration and the elimination of possible dangerous braking.
