“…To reduce the ISD‐related crash risk, it is critical to understand how drivers' IFOV at conflicting intersections impacts emergent collision avoidance performance, which depends on each individual driver's judgment, capabilities, and response to conflicting vehicles in the emergent situation. Considerable efforts in the field of emergent collision avoidance have been devoted to analyses of the influence of the drivers age , gender , driving experience , drug/alcohol use , physical impairment, distraction, driving environment , collision avoidance warning devices , and warning time . However, another important factor—drivers' IFOV—has received only limited attention.…”

SUMMARYProper intersection sight distance can effectively lower the possibility of intersection accidents. American Association of State Highway and Transportation Officials (2011) provide a series of recommended dimensions of intersection sight triangles for uncontrolled and stop/yield-controlled intersections. However, in reality, although the actual intersection design for unsignalized intersections satisfies the requirements of sight distance and clear sight triangle in American Association of State Highway and Transportation Officials' guideline, there are still a large number of crashes occurring at unsignalized intersections for drivers running stop/yield signs or failing to slow down. This paper presents a driving simulator study on pre-crash at intersections under three intersection field of view (IFOV) conditions. The aim was to explore whether better IFOVs at unsignalized intersections improve their emergent collision avoidance performance under an assumption of valid intersection sight distance design. The experimental results show drivers' ability to identify potential hazards to be significantly affected by their IFOVs. As drivers' IFOV improved, drivers were more likely to choose braking actions to avoid collisions. Better IFOVs were also associated with significant increases in brake time to intersection and significant reductions in deceleration rate and crash rate, thus leading to a lower risk of traffic crash involvement. The results indicate that providing a better IFOV for drivers at intersections should be encouraged in practical applications in order to improve drivers' crash avoidance capabilities.

“…Several studies have investigated the effectiveness of collision warning alerts. One such simulator study examining the effectiveness of audio alerts for an intersection collision warning system showed that drivers receiving the auditory alert had a shorter reaction time, lower speed and reduced crash rate compared to drivers receiving no such alerts (Chang et al 2009). In a distracted driving context, a simulator study by Lee showed that graded warnings provided a greater safety margin and elicited fewer inappropriate responses to poor alarms from drivers (Lee, Hoffman & Hayes 2004).…”

Summary: Forward roadway collision warning systems can reduce rear-end collisions, among other unsafe behaviors. Previous studies have shown that young drivers fail to scan adequately for latent hazards. The current driving simulator study investigates the effect of visual collision warning messages on drivers' hazard anticipation ability, when presented either 2s, 3s or 4s in advance of a potential threat. This experiment examined the latent hazard anticipation behavior of forty-eight young drivers aged 18-25 across eight unique scenarios both, in the presence, and absence of visual collision warning alerts. The analysis of glance data captured using an eye tracker, show that visual warning messages significantly increased the proportion of latent hazards anticipated regardless of hazard type (pedestrian or vehicle). The 2s warning duration was found to statistically have the same effect on hazard anticipation compared to the 3s and 4s warning thresholds. The study has potential implications for the effective design of forward collision warning systems.

Intelligent Transportation Systems (ITS) will change the experience of driving in the near future. Most applications will use wireless communication (cellular or ad-hoc) for being able to provide the required services. Usually performance evaluations of communication protocols are conducted with typical network metrics like delay, jitter, or goodput for example. However, in the context of ITS it has been shown that network metrics are not sufficient to evaluate vehicular safety applications. Therefore, we extended our existing simulation framework Veins with a model that allows to simulate dangerous road traffic safety situations, i.e., we implemented a driver behavior model for intersection approaches. Furthermore, we implemented an autonomous controller which tries to avoid crashes at intersections. We showcase the impact of different Inter-Vehicle Communication (IVC) protocols, although the intersection approach model and autonomous controller could be also employed to carry out safety evaluations of other communication technologies.
