“…Some recent studies tackled the subject of V2P communications. The authors in [6] investigated the communication channel at 5.8 GHz between a stationary pedestrian and a vehicle in an urban environment. Based on the measurement data, the Rice model was found to characterize the observed small scale fading.…”

Thousands of fatalities among pedestrians are caused every year by traffic accidents. Vehicle-to-pedestrian (V2P) communication promises to prevent accidents by enabling collision avoidance application. To develop and test a V2P communications system, accurate knowledge of the propagation channel is essential. However, only limited analysis of V2P channel have been reported in the literature. To fill this gap, the German Aerospace Center conducted an extensive channel sounding measurements campaign in a controlled environment. The measurements were performed at 5.2 GHz with a bandwidth of 120 MHz. In parallel to the channel sounding measurements, performance measurements were carried out using ITS-G5 system at 5.9 GHz and with a bandwidth of 10 MHz. This paper describes the setup and the scenarios for the two measurements. First results on channel evaluation in different scenarios as well as path loss models are presented.

“…Normal and Ricean distributions for large and small scale fading respectively were also reported. In [9], the authors investigated the first-order characteristics of the V2P channel at 5.8 GHz in a business district environment. The K-factor was calculated for different locations of the transmitter (Tx) and Rx antennas and vehicle speeds.…”

Vehicle-to-Pedestrian (V2P) communication is essential to enable a reliable collision avoidance system for vehicles and vulnerable road users (VRUs). In order to develop a reliable communication system accurate channel models are required. However, no dedicated channel model for V2P communication in critical scenarios has been proposed so far. To develop a channel model, we conducted wideband channel sounding measurements considering a typical collision scenario between a vehicle and a pedestrian in line-of-sight (LoS) and non-LoS (NLoS) situations. The wideband measurement data is used to study the characteristics of large-scale or shadow fading, pathloss and diffraction loss. The spatial correlation of shadow fading is examined and different models are proposed. For NLoS scenario, a 3D scenario model is designed to simulate the diffraction at a row of parked vehicles. The diffraction loss due to parked vehicles is analyzed and modeled based on multiple knife-edge diffraction model combined with a two-ray pathloss model. The results show that the proposed diffraction model provides a good match to the measured pathloss.

“…While previous measurements performed for channels involving people and separately channels involving vehicles have provided valuable insights, the differences in antenna type, height, mounting position, and the operating environment will result in fading conditions that are unlikely to accurately depict those experienced within the P2V channel. Previous work by the authors [34]- [36] has presented some initial insights pertaining to the fading characteristics that occur within P2V communications channels. In [34], radio channel measurements were conducted at 5.8 GHz between a moving vehicle at different velocities and with a stationary pedestrian positioned by the side of the road.…”

“…Furthermore, by keeping the speed of the vehicle consistent and introducing scenarios where the pedestrian was walking, we have been able to examine how the movement of the pedestrian's body will further impact the P2V communications channel. Lastly, we investigate different antenna positions on the vehicle from those previously studied in [34]- [36] including the often-omitted wing mirror positions, that as we shall see in the sequel actually prove to be valuable and worth consideration for P2V communications. The remainder of this paper is organized as follows.…”

As wireless connectivity becomes increasingly ubiquitous, a greater emphasis will be placed upon the seamless integration of dissimilar networking technologies. One such example of this will occur in urban environments, where wearable devices and vehicular networks will operate in close proximity to one another. Clearly, a natural extension to both types of network is their interconnectivity through vehicle-to-pedestrian (V2P) or equivalently pedestrian-to-vehicle (P2V) communications as part of a much greater vehicle-to-X (V2X) based Intelligent Transportation System (ITS). To this end, we empirically investigate the P2V communications channel at 5.8 GHz for the case of a moving vehicle when a person positioned by the edge of a road was either stationary or walking parallel to the side of the highway. The measurements considered a chest mounted transmitter and four receiver locations on the vehicle covering the front wing mirrors and two positions on the roof, which simultaneously recorded the received signal power. To characterize the propagation mechanisms which are responsible for shaping the received signal in the P2V channel we decomposed it into its path loss, large-scale and small-scale fading components. We first show that although there was evidence of interference caused by multiple rays interacting with one another, the popular Two-Ray ground-reflection path loss model was unable to adequately describe the compounded effects of the vehicle and pedestrian's body on the signal attenuation in the majority of the considered scenarios. Instead, we found that the overall path loss was well characterized using a dual-slope log-distance model, with lognormal large-scale fading. Due to the often severe small-scale fading that was observed in the P2V channel, we have been able to utilize the κ-µ Extreme distribution with considerable success to characterize the worse than Rayleigh fading conditions which were encountered.
