Assessing the impact of inter-vehicle communication protocols on road traffic safety

Abstract

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.

Veins: The Open Source Vehicular Network Simulation Framework

“…For a detailed description we refer the reader to IEEE 802.11e and IEEE 802.11p [18,15,53] and the actual standardization documents [25] and [24]. The level of detail in Veins' MAC and PHY layer implementation allows researchers to conduct various simulation studies, e.g., comparing wireless network performance [14,57], studying the applicability of the wireless network for vehicular cooperative safety [26] (Section 3.2) or the analysis of platoons [50] (Section 3.1).…”

“…Depending on the vehicular safety application under investigation simulation time steps between 1 ms and 100 ms will be reasonable. For a detailed analysis of the simulation time step we refer the reader to the literature [26]. In the following, insights on how Veins can be used to research safety metrics and situation-aware communication for IAS are shared.…”

“…Basically, a detailed analysis of message arrival times (which can be recorded in OMNeT++) is sufficient. The following three metrics represent a basis for evaluating communication strategies of safety applications (details in [26]):…”

“…It serves as the basis of hundreds of publications and contributed to the standardization process of Inter-Vehicle Communication (IVC). Common fields of application include channel access control [14,57], safety applications [26,54], privacy [17] and security [44], platooning [48], communication with traffic lights [13], electric vehicle operation [3], as well as traffic optimization [65]. For some of these uses cases there exist dedicated extensions for Veins such as Prext for location privacy [19], Plexe for platooning [50], an extension to incorporate a real world driving simulator [2], or a simulation framework for electric vehicles [3].…”

Design of Wireless Positioning System Based on Technology of Communication Between Vehicle-to-Vehicle

“…The vehicle-to-vehicle communication technology contributes to the active safety and traffic safety and improve the efficiency of the vehicle,which has become the important research direction of driver assistance technology [1][2][3].It can significantly improve the situation of road traffic inter vehicle information sharing,ensuring the driving safety.…”
