Field trials are conducted, with each of 16 subjects undertaking two driving conditions, each on a different route, one with visual guidance information only, and the other with both visual and auditory information. Half the subjects immediately after completing a manoeuvre are briefly given advance information messages warning them of the distance to, and nature of the next turn from the road ahead. Perceived mental workload, frequency and duration of glances to the display, and subjective views are measured. The presentation of visual and auditory information is the preferred mode, reducing both mental workload and time spent looking at the display. Advance information helps in the navigation task, but does not reduce the glance frequency or duration to the guidance display.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"146 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":"134124332","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 exists the possible distracting effect of the onboard gadget on the driver. Congestion avoidance may improve traffic safety on the network. Thus, reducing congestion on freeways by diverting traffic to alternative arterials is expected to reduce the accident risk on freeways. However, safety on these arterials may be reduced as they become more congested. A methodology for predicting changes in accident rates as a result of traffic diversion by ATIS in Orlando's Transportation Network is presented.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"11 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":"133149637","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 effects of the GPS line-of-sight requirement and Loran-C signal interference and attenuation in urban and mountainous areas are discussed. Unaided GPS and Loran-C signal availability statistics sufficient for 2D positioning with HDOP < 5 are presented using GPS and Loran-C signal statistics. In Calgary, GPS availability is found to be better than Loran-C. This is attributed to a near complete satellite constellation and to the use of a fast signal acquisition GPS receiver. The use of integrated GPS/Loran-C improve GPS availability by only a few percent. In the mountains, the use of an integrated system increases availability to 95% as compared to 65% for GPS and 75% for multi-chain Loran-C.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"96 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":"121573639","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}

IVHS technology is loosely-coupled, that is, the many different subsystems in the overall IVHS system are largely insulated from one another, so that changes to subsystems or additions of entirely new subsystems have little effect on other subsystems. This loose coupling resolves a tension that is present in every technology program: the tension between institutional interests of participants and the functionality of the new technology. The loose coupling of IVHS allows for the interests of participants to be met without undermining the functionality of the technology.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"5 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":"125294354","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 a number of benefits to using odometry as opposed to an INS technique, including high physical robustness and reliability of the encoders, low weight, power consumption and cost, and a zero time-dependent drift. It would seem logical to include some form of odometry on any autonomous surface vehicle. If an INS technique is to be implemented, then it follows that an attempt should be made to improve the overall system performance by combining INS and odometry signals into an optimal, or at least more robust, estimation system.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"64 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":"124137829","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}

Errors of two kinds are considered: errors of geometry which are correctable within VNIS systems by map-matching hardware, software, and algorithms; and errors of topology which may not be easily correctable by common hardware or software strategies. Comparison of two vendors' digital maps of State College, Pennsylvania with each other illustrates both kinds of errors, and also points out that the impact of errors may depend greatly on the context of local traffic patterns, which themselves may vary in non-predictable ways. There are thus both functional and dynamic components of map data quality.","PeriodicalId":185945,"journal":{"name":"Proceedings of VNIS '93 - Vehicle Navigation and Information Systems Conference","volume":"13 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":"121468115","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}
