Vehicle-to-vehicle (V2V) communications is anticipated as one of key future services and it imposes challenging requirements on the air interface such as supporting high mobility and asynchronous multiple access. These requirements may not be best addressed by the currently applied waveforms such as Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM). This paper discusses the design and performance tradeoffs of two waveform families frequently discussed in the literature targeting 5G: filter bank multi-carrier with offset quadrature amplitude modulation (FBMC/OQAM) and filtered OFDM (FOFDM) with specific focus on V2V communications by utilizing a realistic geometry-based stochastic V2V channel model. F-OFDM approaches inherit good properties of CP-OFDM and we show considerable gains as compared to CP-OFDM in asynchronous V2V transmissions due to low out-of-band (OOB) radiation achieved by additional per-subband filtering. The typically long filter for FBMC/OQAM leads to low efficiency for short bursts and the use of OQAM makes it non-trivial to adapt certain schemes well-developed for CP-OFDM. However, we show that FBMC/OQAM outperforms F-OFDM approaches in some severe V2V scenarios thanks to even lower OOB radiation by per-subcarrier filtering.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132637445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been the result of city governments promotion of alternative forms of transportation, in the search for finding strategies that help reduce traffic congestion. Although benefits of cycling in congestion and pollution are concrete, in several cities the increment of cyclists has gotten to the point to overflow the infrastructure, deriving in safety risks and gridlocks due to the lack of explicit coordination among cyclists. This paper presents the integration of two strategies that so far have been considered completely independent: cooperative driving and cycling. Our project addresses the coordination of collective behavior of platoons of cyclists that could pervade dedicated express roads such as the London's 18 mile East-West Cycle Superhighway. The proposed platoon-based cyclists cooperative system can be defined as a networked cyber-physical system with an additional challenge related to the human factor. Different from traditional automated platooning, in the proposed system cyclists respond to a Cooperative Adaptive Cruise Control delivered through specific human-machine interfaces (HMI) designed to elicit the expected response from cyclists. A smart bicycle has been implemented to validate the accuracy of the proposed HMI, and simulations of the complete system are provided to determine the impact of the human error factor in the effectiveness of the cooperative cycling system.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133878655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traffic safety applications strongly rely on the exchange of two types of safety messages that have been standardized by ETSI namely Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs). The ETSI's comprehensive and well documented standards present the structures and implementations guidelines of these safety messages yet there is lack of extensive work on the implementation and validation. Therefore, this paper presents a comprehensive architecture and implementation that has been developed to validate the potentials of CAM and DENM messaging capabilities. This paper evaluates the performance of CAM and DENM facilities through a custom IEEE 802.11p (ITS-G5) based prototype (IT2S) deployed in a field trial. The tests validates the CAM performance by tracking vehicles and various performance indicators such the packet error rate (PER), Received Signal strength (RSSI), connection distance between the OBUs and RSU, number of messages transmitted, GPS coordinates and successful packets received. Similarly, DENMs are validated by events such as traffic information, hazardous location and accidents. These tests motivate towards the unified solution for the implementation of a complete ITS.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126177923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are not many works on urban traffic incident detection. In addition, the traffic data used in detecting an incident are still mostly collected from fixed sensors such as loop detectors. With the advances in mobile sensing and vehicular technology, it is foreseeable that mobile sensors will be used increasingly in the near future. In fact, traffic data will be collected directly by vehicles. Detecting traffic incidents in an urban road network with the traffic data collected by mobile sensors poses several challenges. First, the urban roads are uncontrolled-access roads, which are typically full of flow-disruptive entities such as traffic signals, intersections, crossings, bus stops, etc. These entities can disrupt the traffic flow in a similar way that an incident does, making it more difficult to detect an incident. Second, it is still not clear which traffic variables, collected by mobile sensors, can be used in detecting an incident in an urban environment. In this paper, we investigate and identify the traffic variables that are effective in detecting an incident in an urban road network. Particularly, speed, acceleration, lane-change ratio and travel time are studied. The results show that these four traffic variables are generally effective for traffic incident detection. However, among the four variables, the least effective one is the travel time.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"52 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123213814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a major challenge is that the vehicle-to-ground communication links may suffer from insufficient bandwidth, long round-trip time, and high packet loss rate. Although multiple wireless networks, such as WiFi, 3G and 4G, may be available along the track, onboard users can hardly have a good experience if they can only visit the Internet via one wireless network because of the limitation of the user devices, e.g. laptops with WiFi. The wireless network supported by a device may be subjected to coverage gaps and signal attenuation. In this paper, we first measure the link qualities of multiple existing 3G and 4G technologies, which are candidates for the vehicle-to-ground communication, in a typical high-speed environment on high-speed trains in China. Then, a concurrent multipath transmission scheme is proposed, which provides transparent and effective Internet services for the users through multiple available wireless technologies, without requiring the participation of the user devices in any multipath signaling. Experiments show that the scheme can improve QoS (Quality of Service) of Internet on board by increasing the available bandwidth and reducing the packet loss rate.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123158051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing the LED headlamps and taillights as the transmitter and a photodiode as the receiver, V2LC has high reliability even in high vehicle density scenarios, can effectively identify the transmitter of a received message, and has low cost. In this paper, we identify a new problem unique to V2LC - link asymmetry, which is defined as significant difference in incoming and outgoing links and perform the first experimental work to characterize the problem. To this end, we performed extensive optical radiation pattern measurements with off-the-shelf LED headlamps and taillights. We also collected a number of vehicle mobility traces with 2-dimensional locations with centimeter-level accuracy as well as vehicle bearing. Combining these data, we performed an analytical study to obtain an experimental distribution of received power difference of the links in opposite directions. Our results show that in 80% of the cases the received power of the outgoing link using the headlamp of our vehicle is 22 dB or more than the received power of the incoming link using the neighboring vehicle's taillight, and only 8.1% of the cases have less than 10-dB received power difference. This suggests that the link asymmetry problem is very severe in V2LC and new system design or protocol design consideration is required to prevent significant throughput degradation.","PeriodicalId":399816,"journal":{"name":"2015 IEEE Vehicular Networking Conference (VNC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
