“…EEG readings show two specific wave patterns specific to the human form: N170 at 170 milliseconds tied to facial recognition, and mu wave suppression tied to mirroring biological movement (Bentin, Allison, Puce, Perez, & McCarthy, 1996;Hobson & Bishop, 2017). The innate ability to recognize people in our visual field is limited by the perceptual narrowing that occurs due to the driving task, especially at higher speeds (Jo, Lee, & Lee, 2014;Rogers, Kadar, & Costall, 2005), the neurological priority for recognizing people remains and has a direct impact on driver behavior (Guéguen, Eyssartier, & Meineri, 2016).…”

Maintaining driver attention is critical in multimodal urban spaces where risks to vulnerable users are not borne by the drivers that impose them. However, without an understanding of what it is within the built environment that elicits appropriate driver attention, it will be difficult to reduce the escalating tide of pedestrian fatalities we currently are experiencing. This study uses eye glance data from a naturalistic driving study tabulated for on-task vs. off-task driving and detailed tabulations of environmental variables to identify which features within the built environment have a significant impact on driver attention. An econometric utility model was generated that identified corridor pavement width, reduced drivewayspacing, and linearly aligned street trees as design features that have a positive impact on driver attention.One-way streets, undelineated parking or unstriped bicycle lanes reduce drivers need to attend. Recommendations for maintaining driver attention within urban spaces are included.

“…It is noteworthy that the changes in Q0 and S1 are more substantial when α is ≤1 • and the maximum variations can attain 40% and 20%, respectively. For high-level highways (s ≈ 80 m~450 m [17]) with high vehicle speed v (v ≥ 80 km/h) and an extended driver-attention area, it is evident that the reflection conditions of the road surface within the driver's attention area vary considerably.…”

“…Additionally, the CIE road surface reflection classification system utilizes 1 • as the observation angle α for collecting the reflectance data, which corresponds to a driver's point of view at a height of 1.5 m and a driver's attention area from 60 m to 160 m ahead. But, with the rapid development of urban road construction and vehicle manufacturing technology, the range of the driver's attention area has increased up to 20 m~450 m ahead [17], and the height of vehicles has expanded to 1.4 m~3 m [18]. Meanwhile, due to the need for the seat recline angle [19] and the distance between the driver's eyes and the interior rear-view mirror [20], the height of the driver's viewpoint can reach 1.2 m~2.5 m. As a result, the range of the actual observation angle α for contemporary drivers can be extended to 0.15 • ~7.12 • .…”

To optimize the lighting design of urban roads in China and improve traffic safety, the present study conducted a 10-year longitudinal experiment on urban asphalt roads in Zhejiang Province, China, and analyzed variations of the road surface’s reflective properties and lighting quality with different service lengths, surface areas, and observation angles. The results showed that these roads were R2 roads with low resilience and strong directional reflection. The average luminance coefficient Q0 reached maximum and minimum at the beginning and after around one year of service, respectively. After four years of service, Q0 was about 80% of its initial value and remained stable. The specularity factor S1 reached a maximum of around two years of service. The average luminance Lav was approximately 35%, and overall luminance uniformity U0 was 31%, lower than that of R3 roads during the toughest period of the service life. If the lighting design follows the 1° observation angle r-table recommended by the specification, high Lav and low U0 occur for roads like expressways, leading to a significant increase in traffic safety risks; collector roads may suffer from insufficient Lav. Urban asphalt roads in Zhejiang Province, China, should use the R2 road standard and increase the design value of Lav by 35–45%, and high-level roads should increase the design value of U0 by 40%. The present study will provide scientific references for the design of lighting for urban roads in China, thus promoting long-term sustainable traffic safety in cities.

“…Therefore, drivers' dynamic visual features are most closely related to traffic accidents. 22,23 Some research findings demonstrated that vehicle speed significantly influences drivers' visual features [24][25][26] and high driving speed increases visual perception difficulty and directly influences driving safety when driving through a tunnel portal. Therefore, it is important to investigate drivers' eye movement features around the tunnel portal under different vehicle speeds as it could shed light on strategies to reduce traffic accidents.…”

This study presents the results of a driving experiment study on spatiotemporal characteristics of drivers’ fixation when entering a tunnel portal with different driving speeds. The study was performed during the daytime in a relatively long tunnel. Six experienced drivers were recruited to participate in the driving experiment. Experimental data of pupil area and fixation point position (from 200 m before the tunnel to the tunnel portal) were collected by non-intrusive eye-tracking equipment for three predetermined vehicle speeds (40 km/h, 60 km/h and 80 km/h). Fixation maps (color-coded maps showing distributed data) were created from fixation point position data to quantify visual behaviour changes. The results demonstrated that vehicle speed has a significant impact on pupil area and fixation zones. Fixation area and average pupil area had a significant negative correlation with vehicle speed during the daytime. Moreover, drivers concentrated more on the tunnel entrance portal, front road pavement and car control wheeling. The results revealed that the relationship between pupil area and vehicle speed fitted an exponential function. Limitations and future directions of the study are also discussed.
