“…Among these technologies, alert/notification to users (e.g., through mobile phone alert) is the only connected way considered. Several works have been published in the last years on this topic; some of these works, like [62,63], consider a IEEE 802.11p V2P communication, demonstrating a probability to inform the VRU around 0.8 with a beacon generation frequency at least equal to 1 Hz (for IEEE 802.11p, a unique Provider Service Identifier (PSID) to identify applications for the safety of VRUs is defined by standard [64]).…”

Mobility as a service is becoming a new paradigm in the direction of travel planning on the basis of the best service offered by the travelled roads. Hence, the environment in which people move will become smarter and more and more connected to grant services along the whole path. This opens new challenges related not only to the on board connectivity and wireless access technologies, but also on the reliability and efficiency of the surrounding environment. In this context, reconfigurable meta-surfaces play a crucial role, since they can be used to coat buildings, vehicles or any other suitable surfaces and let the environment become an active part of the communication system by opportunistically redirecting (i.e., reflecting, without generating new waves) signals to the target receivers. The objective of this paper is to highlight the limits of current wireless access technologies for vehicular scenarios and to discuss the potential impact of a smart environment made of reconfigurable meta-surfaces on some next generation vehicular use cases, such as cooperative driving and vulnerable road users (VRUs) detection. In addition, a preliminary model is presented to derive, in a simplified way, the performance of an IEEE 802.11p network in terms of collision probability. Even if analytical and based on simplified assumptions, this model has been validated through simulations and allows to compare the performance of the network with and without reconfigurable meta-surfaces.

“…This communication can happen either directly using ad-hoc communication technologies, such as IEEE 802.11p, or indirectly using infrastructure-based communication, such as, cellular technology. Also, V2P system performs its operation in three phases: detection, tracking and trajectory prediction, and action [14]. These elements have led to different V2P system architectures.…”

In the last few years, increasing attention has been provided to research Vehicle-to-Pedestrian (V2P) communication systems. These V2P systems serve different purposes (safety or convenience) and cater to different Vulnerable Road User (VRU) groups. Also, these V2P systems employ different communication technologies, and use different mechanisms to interact with the users. An effective V2P system also needs to consider varying characteristics of different VRUs. These various elements may be considered as design parameters of the V2P system. In this paper, we discuss such elements and propose a design framework for the V2P system based on them. We also provide an extensive survey of existing V2P efforts for safety and convenience applications and their design considerations. We perform a case study that compares the different approaches of V2P safety system for different VRU groups under different pre-crash scenarios. Finally, we discuss a few technological challenges in integration of VRUs into V2X systems.

“…Some of them have focused on the possibility of using smartphones to establish Person-to-Vehicle communications, and transmit pedestrian's location data (i.e., beacons). The radio technologies considered are Wi-Fi direct [19], Wi-Fi [22], 802.11p [26,28] or cellular [24,25,27,29]. In addition, the new advances in 5G cellular networks, with the arrival of Device-to-Device operations [32], can open new communication alternatives that can be useful for pedestrian protection systems.…”

“…On the other hand, given the large number of pedestrians and vehicles in populated urban areas, a key issue that has been studied most recently is network congestion (e.g., [18,26]) caused when safety messages are exchanged by pedestrian and vehicles. These safety messages could be standard C-ITS messages (e.g., using ETSI ITS-G5 in Europe) [26,28]. These works show that the congestion of the wireless channel can have a significant impact on the loss and latency of messages.…”

Reducing Unnecessary Alerts in Pedestrian Protection Systems Based on P2V Communications

et al. 2019

There are different proposals in the literature on how to protect pedestrians using warning systems to alert drivers of their presence. They can be based on onboard perception systems or wireless communications. The evaluation of these systems has been focused on testing their ability to detect pedestrians. A problem that has received much less attention is the possibility of generating too many alerts in the warning systems. In this paper, we propose and analyze four different algorithms to take the decision on generating alerts in a warning system that is based on direct wireless communications between vehicles and pedestrians. With the algorithms, we explore different strategies to reduce unnecessary alerts. The feasibility of the implementation of the algorithms was evaluated with a deployment using real equipment, and tests were carried out to verify their behavior in real scenarios. The ability of each algorithm to reduce unnecessary alerts was evaluated with realistic simulations in an urban scenario, using a traffic simulator with vehicular and pedestrian flows. The results show the importance of tackling the problem of driver overload in warning systems, and that it is not straightforward to predict the load of alerts generated by an algorithm in a large-scale deployment, in which there are multiple interactions between vehicles and pedestrians.
