With recent developments in technology it is possible for the vehicles to be equipped with communication and GPS systems. The equipped vehicles on the road can act as nodes to form an ad hoc network. These nodes can collect information regarding traffic conditions such as position, speed and direction from other participating nodes. Depending upon the number of participating nodes this collected information can provide useful information of driving conditions to the node collecting this information. With proper analysis this information can be used in detecting and or predicting traffic jam conditions on the freeways. In this paper the traffic information gathered by a node in an ad hoc network is viewed as a snapshot in time of the current traffic condition on the road segment. This snapshot is considered as a pattern in time of the current traffic conditions. The pattern is analyzed using pattern recognition techniques. A weight of evidence based classification algorithm is presented to identify different road traffic conditions. The developed algorithm is tested using data generated by microscopic modelling of traffic flow for simulation of vehicle or node mobility in ad hoc networks. Test results are presented under assumption of different levels of vehicles equipped with communication capability.","PeriodicalId":106396,"journal":{"name":"2007 7th International Conference on ITS Telecommunications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123811240","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}

The protocol is capable of handling both broadcast as well as unicast messages for a particular node. The protocol implements controlled flooding in an efficient manner to reduce unnecessary communication overheads. The protocol avoids forming clusters and clusterheads by using the concept of selective forwarding. Thus it gets the advantages related to clusters without actually forming one itself. It effectively deals with blind flooding by introducing a comprehensive retransmission time delay in the nodes. This retransmission delay favors the nodes in the direction of the destination and restricts other nodes from transmitting the same message again. The proposed protocol avoids the use of routing tables which have a short life in mobile networks needing frequent updates. Instead the protocol relies on directing the messages to geographic locations which are forwarded by any available intermediary nodes. The protocol also provides techniques for handling network fragmentation which is a frequent problem for the vehicular networks. The protocol is implemented using NS2 and simulation results are compared with AODV.","PeriodicalId":106396,"journal":{"name":"2007 7th International Conference on ITS Telecommunications","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130416106","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}

The vision for VANETs is road safety and commercial comfort applications enabled by short-range wireless technology. For a potential integrated solution of VANETs and NEMO, referred to as 'VANEMO', we consider a deployable system architecture and define requirements from a holistic view, taking into account economic, functional, and performance aspects. Next, we regard the vehicular network as a conventional mobile ad hoc network (VANET as a MANET), generalize possible solutions and classify them into two comprehensive approaches: MANET-centric and NEMO-centric. We analyze the two approaches with respect to the VANET specific requirements. We conclude that the MANET-centric approach meets the VANET functional and performance requirements better than the NEMO-centric approach.","PeriodicalId":106396,"journal":{"name":"2007 7th International Conference on ITS Telecommunications","volume":"12 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128217953","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}

We investigated an experimental system that senses the presence and position of pedestrians equipped with an active tag, that sends sensed data to an on-board device of a vehicle near that position, and notifies the driver. Since a pedestrian's pattern of movement at an intersection is complicated, it is difficult to design a perfect motion-pattern model from the beginning. For this reason, we developed a basic movement-pattern model first, and gradually develop this model into a practical movement-pattern model. In this paper, we report on a conceptual image of our experimental system and the basic movement-pattern models for pedestrians developed for the experimental system.","PeriodicalId":106396,"journal":{"name":"2007 7th International Conference on ITS Telecommunications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130675054","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}

The main purpose of this paper is to show the performance improvements obtained by adding more special characteristics to the existing version of MHVB. The enhancement procedure is carried out in two steps: by changing the shape of the backfire region in the algorithm and by introducing a new Dynamic Scheduling algorithm which prioritizes the packet transmission based upon \"processing\" of the received packets from the other vehicles. The key point in the proposal made to enhance the broadcast protocol is the balance between the application requirement and the performance of the protocol.","PeriodicalId":106396,"journal":{"name":"2007 7th International Conference on ITS Telecommunications","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132963937","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}

VANET ( vehicular ad-hoc network ) have been expected to provide new applications for passengers of vehicles, by enabling vehicles to communicate with each other via IVC as well as with roadside base stations via RVC ( roadside-to-vehicle communications ). We propose the COC ( contents oriented communications ) system on VANET via IVC.

Fleet management is especially concerned by this problem. Moreover, for the EUR05 norm to be fully efficient, the driver becomes a key player. By coaching truck drivers to avoid bringing their vehicles out of their optimal working range and to better anticipate the obstacles, significant economy savings in fuel and equipment can be achieved. In this context, we show that Information and Communication Technologies bring a new solution. Indeed, it is now possible to acquire the necessary data from the vehicle in order to analyse the driving behaviour of the driver. This paper describes a solution for solving optimal driver coaching issue, involving an access to vehicle data, a solution for data transmission on-board and off-board, and an efficient processing capability.
