We have studied biological signals of a driver to detect drowsiness during driving. Our former research suggested a method analyzing changes in indexes derived from biological signals, however the method needs to be configured for each driver because the relation between the indexes and the drowsiness depends on individuals. To analyze the indexes in consideration of the individual differences, neural networks was used in this paper. The learning function the networks was utilized to adapt to the differences. We conducted a experiment that 6 drivers drove a driving simulator to gather their pulse wave and steering data. As the result of learning and analyzing the indexes in neural networks, 98% of the highest ratio was shown in detection of driver's drowsiness. A method of detecting driver's drowsiness is a need for realization of safer traffic environment. The proposed method would contribute to prevent traffic accidents caused by human errors in a drowse.","PeriodicalId":153203,"journal":{"name":"Proceedings. 2005 IEEE Intelligent Transportation Systems, 2005.","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128708004","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 fundamental difference from an economic point of view is that cellular networks follow a 'pay-per-use' paradigm with 'per minute' or 'per kbyte' charges, whereas commercial broadcast services (e.g. pay-TV) are charged for by long-term (months or years) subscriptions. In this paper, we investigate a hybrid system for carrying traffic information services. It comprises a data broadcast network for providing the base capacity and a cellular network for carrying the peak traffic exceeding this base capacity. Cellular capacity for the excess data traffic can be purchased whenever needed. However, capacity in broadcast networks is typically leased for long periods of time (potentially several years) at a fixed price. The key problem is how to choose depending on the statistic properties of the input data traffic - the fixed broadcast capacity such that the overall operation cost for the hybrid network is minimized. Results for a telematics service delivering traffic information show that indeed considerable cost savings can be achieved by carefully balancing the capacity allocated in the broadcast network against the peak traffic redirected through the cellular network. The simple analytical model proposed to aid in this tradeoff is validated by simulations.","PeriodicalId":153203,"journal":{"name":"Proceedings. 2005 IEEE Intelligent Transportation Systems, 2005.","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127045988","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}

Specifically, attacks on the urban transportation system can cause great disruption and alarm, which are the traditional goals of terrorism. The unexpected and stochastic character of terrorist attacks poses unique challenges to those responsible for security. Since the threat of terrorism is obscure and security measures are costly, it is hard to justify the expenditures before an attack. Security against terrorism therefore tends to be reactive. In this paper we propose new ITS technologies to enhance the surface transportation aspects of homeland security, by providing more efficient and safer evacuation for general public in case of terrorist attacks or other human caused disasters. In particular, we extend our existing work on developing a smart traffic evacuation management system (STEMS), by enhancing it with capabilities to adapt to the dynamics of the traffic environment, by leveraging real-time information obtained from sensors or other surveillance technologies. STEMS handles the unexpected aspect of terrorist attacks or other unpredictable disasters, by generating evacuation plans dynamically, when given an incident location and scope. To handle traffic dynamics, STEMS will continue to revise the initially generated plan, during the evacuation operation, to keep it consistent with the continuously changing traffic conditions. The advantages of this revision process are two-fold: first, it ensures that traffic will not be directed towards congested areas; and secondly, it decreases congestion by spreading the traffic from currently congested segments to alternative routes. Our simulation studies show that employing real-time information greatly improves STEMS performance and therefore, evacuation efficiency.","PeriodicalId":153203,"journal":{"name":"Proceedings. 2005 IEEE Intelligent Transportation Systems, 2005.","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115923795","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}

Data flow Petri nets that we studied are an efficient solution to make it possible, combined with the use of a hardware description language, so that they can be implemented on programmable chips. The example described in this paper deals with a wheelchair whose hand lever can adapt to the user's handicap. For some disabled people, the use of a wheelchair can be difficult, for physical or cognitive impairments. Moreover, a choice has been made for modular structure and non-specific material for practical reasons. Therefore, the Fauteull Roulant A Commande Adaptee au Handicap (wheelchair with adaptive command for people with disabilities) project has been developed. The lever is handled by an artificial neural network that records functional limitations of the hand, and then compensates them. First experiments and first implementation studies of a neural network give encouraging results.","PeriodicalId":153203,"journal":{"name":"Proceedings. 2005 IEEE Intelligent Transportation Systems, 2005.","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130037427","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}
