“…In [11], the authors consider an intersection collision warning application, and evaluate PDR and RSSI as a function of the distance of the two vehicles from the intersection. The authors consider different transmit power values in their study, and conclude that intermediate power levels can provide good performance while at the same time reducing congestion in the wireless channel.…”

“…Thus, understanding beaconing performance is a fundamental step in the process of designing active safety applications. This explains the considerable attention that the vehicular networking community has devoted to the study and optimization of beaconing [1,6,11,12,25,29,32], including recent measurement-based studiessee Section 2. In particular, two parameters have been identified as the most relevant to characterize beaconing performance: the beacon delivery rate and beacon inter-reception time.…”

“…Interestingly, this is an ambiguous question whose answer is not clear, yet, to this date. In fact, when resorting to literature, we find that different studies experienced different transmission ranges, from as low as 70 m to almost 500 m [10]- [12]. Such uncertainty is confirmed by standardization entities, which have not yet finally determined how dedicated short range communication channels will be utilized [13].…”

The UN Economic Commission's Statistics of Road Traffic Accidents report of 2011 shows that every year, about 150 000 human beings lose their lives on the roads of the western world. Although it is a common belief that this figure could shrink with the use of new sensor and communication technologies, unfortunately, none such systems have hit the road to date. Ideally, if such technologies were put into place, vehicles could be part of a vehicular ad hoc network (VANET) capable of spreading relevant information about dangerous events (e.g., car accidents) to all approaching drivers. However, all this is mainly supported by simulation studies, as no practical results have been published to date, revealing the effective performances of such systems at work. In this paper, we fill this gap, presenting a detailed description of the greatest experiments (a few thousand throughout the streets of Los Angeles), to date, ever performed with an accident warning system specifically devised for highway scenarios. In particular, among all the possible candidate schemes, we ran a few thousand experiments with the accident warning system algorithm that was proven to be optimal in terms of bandwidth usage and covered distance in realistic scenarios. Our experiments confirm what has been observed before in theory and simulation, i.e., the use of such a system can reduce, by as much as 40%, the amount of vehicles involved in highway pileups.

INTRODUCTION T HE SOCIETAL costs of car accidents in Europe, in year 2009, amounted to $160 billion according to the Harmonised European Approaches for Transport Costing project commissioned by the European Union (EU) [1]. Such value only partially captures the plethora of problems that have their origin in such type of events, as it is rather difficult to quantify, for example, the costs that are imputable to the emotional distress symptoms or to the increased pollution levels that usually follow any motor vehicle accident. Continuing with a policy that recognizes the negative impact that car accidents have on society, in July 2011, the Transport Manuscript

“…However, even with the boosted signal strength that is allowed by current Wireless Access in Vehicular Environments (WAVE) standards [1], the necessary transmission ranges cannot be reliably obtained through single-hop communications. In urban areas, some experimental measurements data indicate a maximum range of 100 − 150 m even with 33 dBm boosted transmission power [9]. Furthermore, the range is further reduced when transmission power is lowered to improve spectrum spatial reuse.…”

Many vehicular safety applications depend on the rapid and reliable dissemination of safety messages to vehicles at risk. In order to allow sufficient reaction time for emergency events in adverse driving and road conditions, disseminating safety messages over multi-hop vehicles is often needed. However, owing to the capacity limitation of the shared control channel, disseminating safety messages in highly mobile and dynamic vehicular network conditions is challenging. In this article, a Zero-Coordination Opportunistic Routing (ZCOR) algorithm is proposed to deliver mission-critical life safety messages over limited target geocast regions. ZCOR is scalable and robust over dynamic VANET conditions with low rebroadcast overhead. In addition, ZCOR exploits neighbor knowledge for coordinationfree opportunistic packet relay using the novel concept of Circle of Trust (CoT), which defines the range of reliable local neighbor knowledge collection. The performance of ZCOR is evaluated through extensive and realistic simulations capturing time-correlated vehicular channel characteristics.
