“…Furthermore, we classified crashes as being related to glare when the angular distance between the driver’s line of sight and the sun was between 0° and 45°, a threshold based on research in Japan 13. Further research adopting more stringent thresholds of 10°, 20° or 30° degrees or analysing the changes in this effect for motorists of different ages may attempt to compare their results with ours, as indicated by Jurado-Piña and Pardillo Mayora 9…”

“…Churchill et al 8 employed a geometric model to examine whether sun glare affects the speeds of drivers on roadways and concluded that changes in speed as a result of sun glare affected highway congestion. Jurado-Piña and Pardillo Mayora,9 in an investigation of the maximum tolerable sun glare determined that glare occurs when at specific angular distances between a driver’s line of sight and the sun; these angular distances are 19° for a 40-year-old driver and 25° for a 60-year-old driver. Anue10 suggested that sun glare typically does not occur at angular distances greater than 25°.…”

ObjectivesSun glare is a serious driving hazard and increases crash risks. Relatively few studies have examined the effects of sun glare on pedestrian fatalities, given that a crash has occurred. The primary objective of this study was to investigate the effect of sun glare on pedestrian fatalities.DesignA population-based case–control study.SettingTaiwan.ParticipantsUsing the Taiwan National Traffic Crash Data and sunrise and sunset data from the National Oceanic and Atmospheric Administration for the period 2003 to 2016, 100 411 pedestrians involved in crashes were identified. Of these crashes, 13 355 and 87 056 were glare-related (case) and non-glare-related (control) crashes, respectively.MethodsTo account for unobserved heterogeneity, mixed logit models were estimated to identify the determinants of pedestrian fatalities.Main outcome measuresPedestrian fatalities.ResultsPedestrians involved in glare-related crashes were more likely to be fatally injured than those in non-glare-related crashes (β=0.527; t=3.21). Other contributory factors to fatal injuries among pedestrians were older pedestrians (β=0.553; t=2.33), male drivers (β=0.324; t=2.33), older drivers (β=0.218; t=2.14), intoxicated motorists (β=0.606; t=2.85), rural roadways (β=0.985; t=3.92), overtaking manoeuvres (β=0.472; t=3.58), heavy vehicle crash partners (β=0.248; t=2.78) and sunset hours (β=0.274; t=3.08). Walking against traffic appeared beneficial for decreasing injury severity (β=−0.304; t=−2.76).ConclusionsSun glare is associated with pedestrian fatalities. Older pedestrians, male drivers, older drivers and intoxicated motorists are prevalent determinants of pedestrian fatalities in glare-related crashes.

“…An examination has been directed in Japan to discover the commitment of sun glare in RTAs [119,120]. Depicted that the frequency of RTAs, as a rule, goes higher when sun presentation was before engine vehicles than the person on foot mishaps [121]. They likewise saw that RTAs happened with more noteworthy recurrence when the vehicle has a direct front introduction towards the sun.…”

Evaluating the Nature of Distractive Driving Factors towards Road Traffic Accident

For past two decades many researchers have been working on quantitative as well as qualitative study of distractive driving using different approaches. Road traffic accidents have been identified as the main source of human casualties and cause of damages to the economy and society, as millions of humans is killed every year in these accidents around the world. National-level studies in Pakistan reveal that a higher percentage of males in the age group from twenty to forty years lose their lives in road traffic accidents when compared with that of females. Due to these factors, it is alarming for a society, which is highly dependent on males such as Pakistan, as these losses put numerous families into the financial crisis that lead to poverty. This study envisaged identifying whether moods and emotions play any role in road traffic accidents of young drivers. The study reviews have shown various gaps in our understanding. For this purpose, qualitative interviews of young drivers who are university going and have met some road accidents in recent years in Pakistan had been conducted. Data from the interviews had been transcribed for analysis while maintaining the anonymity of the participants for confidentiality. Analysis of the transcribed data reveals various factors that contribute to road traffic accidents where major causes are distractions, different weather conditions, sleep deprivation, unsafe lane changes, night-time driving, and these factors are triggered by the behavior when youthful drivers engage in driving for sensation seeking and self-esteem. We conclude that it is just through the appropriation of a systems approach that coordinated countermeasures can be proposed and actualized to relieve driver mistakes caused by distraction.

“…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?…”

“…Periods of sun glare have been associated with increased probability for crashes (Jurado-Piña and Pardillo-Mayora 2009). Traffic observations show that there is a reduction in traffic speed and an increase in vehicle headways during times of high glare (Jurado-Piña and Pardillo-Mayora 2009).…”

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.
