This mode of operation brings into question the possibility of using this same VHF equipment to transmit and receive data for position fleet management due to this fundamental advantage. It is possible, although there are a number of limitations and disadvantages in these communication systems, mainly because of the limited propagation properties and the limited availability of channels. These problems can be reduced by means of appropriate system design and data format.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129053991","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 method is called \"conflation\" and its requires identification of the matching elements on both maps: vertices, arcs, and areas. Conflation generally consists of two parts (automatic and manual). The method is based on the usage of the chains of arcs in order to determine the matching intersections between them. The chains are formed a priori by using both attribute and geometric properties of the arcs. The intersections are treated as relations between chains and are stored in a simple external relational database.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132884801","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}

An individual criterion is used in order to route guided vehicles following the Wardrop's first principle (the individual equilibrium), and a collective criterion in order to route guided vehicles following the Wardrop's second principle (the minimization of a collective criterion). The authors study in which conditions in terms of percentage of equipped vehicles and total demand these two methods lead to significantly different numerical solutions. The two guidance methods are formalized by two minimization problems which use flows as optimization variables and differ only for the criteria. The optimization algorithm is based on a recurrent use of Dijkstra method for shortest path. The two approaches are studied simultaneously on three networks.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534504","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 individual communication between infrastructure and vehicles is carried out over roadside beacons with a short range and bidirectional data link. The range varies and depends essentially on the speed of the vehicles, the applied data rate and the offered services. The technical aspects and propagation conditions of a 5.8-GHz mobile channel are investigated by simulation and measurements. The reliability of the data link is considered in multipath fading environment. Field trials at two test sites show that a reliable and suitable data link can be realized, if improvements such as space and frequency diversity techniques are implemented.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132589990","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}
