“…An alerting effect of the speed reduction markings was dominant because v α’ was not larger than v β . This result strengthens the “large alerting device” theory by Jarvis and Jordan ( 33 ) and Godley et al ( 34 ) as well as the findings of Katz ( 23 ) and Hunter et al ( 27 ), who reported different levels of speed reductions spatiotemporally. The speed reduction in advance of the markings also implied the presence of an alerting effect.…”

“…Jarvis and Jordan ( 33 ) reported that yellow transverse bars reduced the approach speeds toward the road markings, concluding that the markings functioned as a large warning device rather than creating the perceptual illusion of acceleration. In a driving simulator experiment by Godley et al ( 34 ), the interval convergence of wide transverse bars and edge lines did not impact drivers’ speed choice. The researchers found a lower mean speed in wide transverse bars than in edge lines during the first 100 m of the markings, concluding that an alerting effect triggered the speed reduction.…”

Speed reduction markings have been installed on highways as perceptual countermeasures for speeding. However, little is known about the effects of the shape and interval of road markings on driving speed and lane position. In this paper, a driving simulator experiment and questionnaires were performed to explore the effects of speed reduction marking patterns on driving speed and standard deviation of lane position (SDLP), as well as drivers’ subjective feelings, mental workload, and visual attention. Thirty-nine participants drove on a simulated two-lane rural highway where speed reduction markings with different shapes and intervals were presented at horizontal curves. The pavement markings were associated with reduced throttle values and mean speed in advance of a horizontal curve. The marking shape did not affect participants’ speed choice or SDLP. A cognitive alerting effect of the speed reduction markings was dominant because the participants did not drive more slowly with the markings with converging intervals toward the traveling direction compared to those with a constant interval. A questionnaire on drivers’ attention reflected a potential use of road markings for drivers’ lane-position maintenance. Since less than 18 % of the participants noticed the convergence in marking intervals, speed reduction markings may also induce the perceptual illusion of acceleration.

“…Godley et al conducted a systematic evaluation of the effectiveness of perceptual countermeasures to speeding [27]. Different treatments (narrower lane widths, inside hatching, centre line hatching, herringbone pattern, and reflector post positioning) were tested using a driving simulator.…”

“…In addition to evaluating the impact of road markings in curves, several studies investigated their impact on driver behaviour while approaching an intersection. Godley et al used driving simulator to evaluate the impact of different treatments (transverse lines, peripheral transverse lines, a herringbone pattern, the Wundt illusion, and trees on the road edge) on driver behaviour while approaching an intersection [27]. e results showed a significant reduction in speed with all treatments.…”

As part of the traffic control plan, road markings form the traffic surface and provide visual guidance for road users. Since their first application to the present day, road markings have become a common element of road infrastructure and one of the basic low-cost safety measures. The aim of this paper is to provide a systematic review of the most significant academic activities to date regarding the influence of longitudinal and transverse road markings as well as road markings for hazard locations (curves, intersections, and rural-urban transitions) on driver’s behaviour and overall road safety. The review includes a total of 71 studies from which are 52 peer-reviewed journal studies, 4 conference proceedings, and 15 professional reports. The studies are, based on their aim, divided into two categories: (1) studies on the impact of road markings on driver behaviour (36 studies) and (2) studies on the impact of road markings on road safety (35 studies).

Three-Dimensional Müller-Lyer Illusion

Since its introduction in 1889, the Müller-Lyer illusion has incited numerous studies and explanations. Most rely on two-dimensional stimuli such as line drawings, subject to the criticism that illusions are restricted to impoverished, artificial stimuli and have little relevance to understanding of ordinary perception. The three-dimensional Müller-Lyer illusion occurs with familiar solid objects and moving observers and has been used to evaluate misapplied constancy theories, perception–action dissociations, and level of processing. The occurrence of illusions in real-world contexts, and in two-dimensional displays upon which people rely increasingly, makes them essential to understand and predict. The three-dimensional Müller-Lyer illusion has significant theoretical and practical implications and continues to be an important concern for visual science.
