“…What's more, lighting is certainly a primary factor that affect the driving performance in highway tunnels. Yeung found that drivers perceived artificial lighting as impairment in their visual performance when compared driver's perspective in open road sections and highway tunnels (Yeung et al 2013).…”

As typical weak visual reference systems, highway tunnels have low illumination, monotonous environment and few references, which may cause severe visual illusion and reduce drivers' speed perception ability. Thus, drivers tend to underestimate their driving speed, which may induce speeding behaviours that result in rear-end collisions. The cost-effective pavement markings installed on both sides of the lane or shoulder may make drivers overestimate their speed. This perception can help ensure safe driving and regulate driving behaviour effectively. This study analyses the effects of sidewall markings in typical low luminance highway tunnels, specifically observing how their angles and lengths affect the driver's speed perception. A three-dimensional model of highway tunnels was built in a driving simulator. Psychophysical tests of speed perception were carried out by the method of limits. The simulation tests studied the Stimulus of Subjectively Equal Speed (SSES) and reaction time in relation to sidewall markings with different angles. Furthermore, based on the optimal angle, the effects of sidewall marking with different lengths on speed perception were also analysed. The test results reveal that the angle and length of sidewall markings have a significant impact on the driver's SSES and reaction time. Moreover, the level of speed overestimation decreases with the increase of angle or length of sidewall marking. As the angle of sidewall marking gradually increases, the maximum reaction time first increases and then decreases. Within the angle of sidewall marking of 15°, the subjects have the highest speed overestimation and an easy speed judgment. This may due to Zöllner illusion, the driver's perception of lane width shrinks may induce deceleration behaviour.

ACCEPTED MANUSCRIPTACCEPTED MANUSCRIPT 2 systems. This technology is spreading fast because of its low energy consumption and the high durability combined with low maintenance requirement. Aim of this research was to assess, by means of a driving simulator experimentation, the impact of the LED lighting system on traffic safety. The driver performance approaching, inside and exiting LED lighted tunnels was analysed and compared to the behaviour maintained in tunnels illuminated with a traditional system, in normal and in critical conditions. Thirty-one young subjects drove through two different virtual scenarios while data on their speed, lateral position and reaction in front of a sudden obstacle in the carriageway were collected. A statistically significant difference was revealed as a function of the type of lighting; simulated LED lights often induced a better driving behaviour under some aspects. The motorists were able to perceive in advance the critical situation and the consequent manoeuvres were carried out in a more effective way. Moreover, drivers kept better their lateral trajectory control in transition areas.

“…The population that is more likely to suffer vision impairments are older drivers, 60 years of age, or older. Numerous studies suggest that eyesight deteriorates with age and it also becomes more sensitive to automatic changes in the environment, resulting in a sight adaptation lag (Jurado-Piña and Pardillo-Mayora, 2009;Auffray et al, 2008;Jurado-Piña, Pardillo-Mayora and Jiménez, 2010;Yeung, Wong and Xu, 2013). So does this make older drivers more susceptible to crashing at or near tunnels?…”

“…Tension makes drivers prone to perform drastic movements that can lead to a crash. A typical behavior in a driver's response to the tunnel is the urge to exit, making them more prone to missing information along the tunnel(Evans et al, 1984;Yeung et al, 2013) and along their peripheral vision. Tension in drivers can be measured by increased heart rate and enlargement of the pupil's diameter.…”

“…Tension in drivers can be measured by increased heart rate and enlargement of the pupil's diameter. Zhao et al (2011) conducted a study where they measured eye tracking together with a multiple parameter detector that measured pupil and heart rate as the driver traveled along a tunnel and found that heart rate and pupil dilation increases on tunnel roads, which is an indication of tenseness and nervousness Yeung et al (2013). found that drivers are more likely to obey speed limits and maintain larger gaps in tunnel roads than in open roads.…”

Tunnel Road Safety: A Look at Older Drivers’ Performance and Sight Impairment

In California, there is an observed trend in which collisions cluster in and around tunnels. The break in road continuity created by the tunnels disturbs traffic flow that can lead to collisions. One of the main contrasts between open roads and tunnel roads occurs in lighting. Drivers with sight deficiencies are unable to adapt their sight to the change in the lighting environment and may crash due to misperception of road alignment, vehicle's speed and other physiological reactions, such as tension. The suspect population group of crashes occurring under the influence of tunnels conditions is older drivers. The literature suggests that sight and driving performance deteriorate with age. This research attempted to validate this claim by performing a study that looked at driver and crash characteristic of injury and fatal collisions that occurred in and around tunnels. The expectation was that a greater proportion of the older population, 60 years and older, would be represented in the crash data. However, this study found that it is young drivers and not older drivers who are more likely to crash in and around tunnels. This finding may be explained by the State of California's vision requirements for the issue of a driver's license, and the voluntary retirement of drivers that feel that they can no longer drive safely.
