Summary The low‐luminance monotonous environment in the middle section of highway tunnels offers few reference points and is prone to cause severe visual illusion. Thus, drivers tend to underestimate their driving speed, which can induce speeding behaviors that result in rear‐end collisions. Therefore, discovering low‐cost methods of traffic engineering that reduce this visual illusion and ensure a steady driving speed is an important challenge for current highway tunnel operations. This study analyzes the effects of sidewall markings in typical highway tunnels, specifically observing how their colors and temporal frequencies affect the driver's speed perception in a low‐luminance condition. A three‐dimensional model of the middle section of highway tunnels was built in a driving simulator. Psychophysical tests of speed perception were carried out by the method of limits. The precision of the simulation model was then checked by comparing the results to field test data. The simulation tests studied the stimulus of subjectively equal speed and reaction time in relation to sidewall markings in different colors (red–white combined, yellow–white combined, and blue–white combined). Furthermore, based on the optimal color, the effects of sidewall marking with different temporal frequencies (0.4, 0.8, 1.2, 2, 4, 8, 12, 16, and 32 Hz) on the speed perception of drivers were also analyzed. The test results reveal that the color and temporal frequency of sidewall marking have a significant impact on the driver's stimulus of subjectively equal speed and reaction time. The subjects have the highest speed overestimation and an easy speed judgment with the red–white combined sidewall marking. Within the temporal frequency range of 4.45–7.01 Hz, the subjects have a certain degree of speed overestimation (less than 20%), and the speed perception is sensitive to the temporal frequency changes.

“…Although Godley et al (2000) found no difference between constant and decreasingly spaced transverse lines, Manser and Hancock (2007) demonstrated that such an effect may exist. Also using a driving simulator, Manser and Hancock tested participants' ability to maintain their driving speed through a tunnel, when the tunnel walls were painted with lines at either decreasing, constant, or increasing distances.…”

“…To do so, research needs to test the effectiveness of equally spaced transverse lines compared to decreasingly spaced lines. Godley et al (2000) conducted such a test, using a driving simulator. They found that both equally and decreasingly spaced transverse lines slowed participants to the same extent.…”

“…1). Several studies have evaluated the effects of illusionary pavement markings on vehicle speeds (Agent, 1980;Griffin and Reinhardt, 1996;Retting et al, 2000;Meyer, 2000;Godley et al, 2000;Drakopoulos and Vergou, 2003;Vest and Stamatiadis, 2005;Katz et al, 2006;Katz and Rakha, 2008;Gates et al, 2008;Voigt and Kuchangi, 2009;Hunter et al, 2010). Most of these studies rely on before-after studies with limited sample sizes.…”
