“…The results demonstrated that individuals exposed to text messaging within the virtual environment reported changes in intentions to cross streets while being distracted by their mobile phone and in perceived vulnerability to risk while crossing streets. In addition, as an emerging solution to address the distraction of mobile phone use while walking/crossing, embedded illuminated lights installed in the footpath can effectively attract the attention of distracted pedestrians, then they may play as warning signals for pedestrians distracted by their mobile phones [60]. Second, Piazza et al [61] found that subjective norm (SN) significantly predicted pedestrians' intention to use mobile devices while crossing street, SN being a psychometric construct determined by normative beliefs concerning the expectations of important referents (e.g., friends, family members).…”

Pedestrian safety is alarming worldwide, and it is well validated that distracted walking/crossing involving mobile phone use would significantly compromise pedestrian safety. Some existing studies demonstrated that distracted pedestrians would spend more time to cross street, miss more safe opportunities to cross and pay less attention to the road environment, etc. As a result, they are more likely to be hit by an oncoming vehicle. Specifically, with respect to the distraction results from mobile phone use for communication in road user groups, previous research has examined the relationship between social networks and mobile phone use among drivers and motorcyclists. However, very little similar research was found in the field of pedestrian study. This study performed an online survey to investigate with whom pedestrians were most likely to communicate with while crossing street in a Chinese sample. The association between social networks and self-reported injury/ near miss event was also examined. To provide an insight into the difference in communication pattern between scenarios, the results were compared with the patterns while driving, motorcycling and the general patterns. Results indicate that pedestrians are most likely to communicate with friends (31.2%), followed by spouses (24.5%). Additionally, participants who frequently talk to parents/children have a greater likelihood of being involved in injury/ near miss events than those talk to the others. Compared with the prevalence of mobile phone use among drivers and motorcyclists reported in previous studies, mobile phone use is more prevalent among pedestrians, especially as they are more likely to communicate with colleagues. In sum, the results demonstrate that social networks play an important role in mobile phone use during street crossing, and pedestrians are more likely to communicate with people who are socially closest to them. The effect of social networks on mobile phone use (especially for communication) among pedestrians should be considered in the development of traffic safety countermeasures.

“…The in-ground lights and signs have been implemented, however, there is not much data on the effectiveness and considerations of in-ground lights and signs. In a recent laboratory study, it was found that in-ground lights caused the faster response of smartphone users compared to wall-mounted light while walking towards the lights (Larue et al, 2020). The findings of their study support the effectiveness of in-ground lights, but it is still not known where the in-ground lights or signs should be installed to deliver key safety information properly and timely.…”

Visibility of an in-ground signal when texting while walking

An increase in pedestrian accidents associated with smartphone use has been one of the main issues in road traffic safety research and administration. Recently, traffic lights and safety signs embedded in the ground have been introduced, but without sufficient scientific consideration. A laboratory experiment evaluated the visibility of an in-ground signal while varying its contrast and position. Twenty-three participants performed a signal detection task when conducting texting while walking on a treadmill. The signals were displayed randomly onto the ground one at a time at three different positions with three different contrasts levels and moved towards a participant. In results, the approaching signals were detected 1.7 m ~ 2.9 m in front of participants, and there were significant differences in the visibility between contrast levels and positions (p<.01). The findings suggest the importance of proper contrast level and placement when installing in- ground signals for improving their visibility by smartphone users.

“…[1][2][3]. With the advancement in wireless communication systems [4][5][6][7], the vision of vehicles communicating with each other and with other devices (e.g., mobile devices and roadside units) situated at various locations (e.g., roads and buildings) is becoming a reality [8][9][10]. For instance, an Internet-connected device (e.g., a mobile device/application) could notify drivers of the proximity of a bicyclist in the street or a pedestrian on a crosswalk [11][12][13][14][15], which could potentially reduce the number of pedestrian-related accidents.…”

Road safety is an active area of research for the automotive industry, and certainly one of ongoing interest to governments around the world. The intelligent transportation system (ITS) is one of several viable solutions with which to improve road safety, where the communication medium (e.g., among vehicles and between vehicles and the other components in an ITS environment, such as roadside infrastructure) is typically wireless. A typical communication standard adopted by car manufacturers is IEEE 802.11p for communications. Thus, this paper presents an overview of IEEE 802.11p, with a particular focus on its adoption in an ITS setting. Specifically, we analyze both MAC and PHY layers in a dedicated short-range communication (DSRC) environment.
