“…Approach speed is reduced for all routes whose first segment is straight, while for horizontal routes that include sharp turns or stop signs, the approaching speed is slightly increased. Despite this slight increase in speed, drivers slow down more intensively during the application of the system [13]. On the negative side, with the active warning system, participants' obedience to the STOP sign decreased by 16.5%, but in case of system failure, most participants had no difficulty in detecting road hazards even though they did not receive any warning message [14], meaning that in-vehicle warning systems have a lasting effect on driver behaviour even after the system is no longer present [15].…”

Enhancing traffic safety is one of the fundamental objectives of Intelligent Transport Systems (ITS), and it aligns closely with the principles of sustainable transport. Due to specific differences in infrastructure, vehicles, and users’ behaviour, places where different modes of traffic intersect are recognized as critical points of the traffic system, making them crucial aspects of Sustainable Urban Mobility Plans (SUMPs) implementation. The SUMPs aim to create urban mobility that is not only environmentally friendly and efficient but also safe for all users. The continuous development and widespread adoption of innovative ITS technologies have paved the way for a system that could provide drivers with real-time information about both immediate and potential dangers at these critical points. This paper provides an overview of previous research in the field, investigating the impact of information systems on drivers’ behaviour, various detection and communication solutions that can be effectively integrated into such a system, as well as a brief overview of models and solutions that have been developed to warn drivers in a similar context. The reviewed literature offered valuable insights on which a novel driver information system architecture framework is proposed. This framework can contribute to the ongoing safety improvement in multimodal transport networks within the context of sustainable transport.

“…The "SAFER Level Crossing" multiagency research project in the European Union has evaluated the use of auditory alerts that would play when vehicles approach crossings in participating countries such as Italy [14]. In Greece, the use of auditory alerts has been evaluated with taxi drivers in the city of Thessaloniki [15], showing the benefit of the alerts and factors to include based on driver feedback. However, the design of the auditory alert was not thoroughly investigated for rail-crossing applications, using past guidance in automotive displays.…”

In-Vehicle Auditory Alert (IVAA) effectiveness depends on several auditory factors. Lead time has been shown to significantly influence IVAA effectiveness for automotive displays, although applications for Highway-Rail Grade Crossings (HRGCs) have yet to modulate and determine an appropriate lead time. To address this research gap, we conducted a small-scale driving simulator study to investigate the effect of lead time variation on driving performance and gaze behavior at rail crossings. We recruited 11 participants who drove through three experimental drives with different alert state conditions. Preliminary results show that a seven second lead time led to statistically higher temporal demand, a slower approach speed to crossings, and better gaze behavior than the no IVAA condition. The seven second lead time condition had similar higher values than the advanced warning condition, although they were not statistically significant. Findings of the current study offer insight into auditory display guidance for HRGCs, although future work involving a larger recruitment pool is needed to confirm study findings.

“…Research on auditory displays for HRGCs has explored driver responses to existing traffic control devices, driver demographics, as well as in-vehicle warning displays (28) and their implementation (29). The SaferLC Project, a multiagency research project funded by the European Union is another example of research in the field that evaluated delivery of HRGC warnings to drivers in Greece (30).…”

Highway-rail grade crossings (HRGCs) present multiple collision risks for motorists, suggesting the need for additional countermeasures to increase driver compliance. The use of in-vehicle auditory alerts (IVAAs) at HRGCs has been increasing, but there are limited standards or guidelines on how such alerts should be implemented. In the current study, we sought to investigate the effect of different auditory display variables, such as display type and acoustics, on subjective user assessments. We recruited 24 participants and asked them to rate 36 different IVAAs belonging to one of three display types (earcons—short synthetic tones, speech alerts, and hybrid alerts consisting of an earcon and speech) along 11 subjective ratings. Results showed that a hybrid alert led to better overall ratings for acceptance, safety, and semantic understanding when compared with earcon or speech alerts. Additional analyses revealed that semantic variables, such as speech order and gender, should be accounted for when designing IVAAs in an HRGC context. Hybrid IVAAs with spatial audio showed lower Urgency and Hazard level ratings. Findings of the current study can help inform the design of IVAAs for HRGCs.
