The Japan Highway Public Corporation has been developing highway radio systems which collect traffic information and automatically broadcast it using a speech synthesizer in order to improve safety and convenience of driving. In such systems, detailed and appropriate information, immediacy, and plain style message are required. However, this is very difficult and an usual speech synthesizer to handle a large variety of messages is required. The authors have developed a new speech synthesis method. In this method, pitch periods of an utterance are modified and sentence intonation is generated automatically when speech data are concatenated. Thus natural sounding sentence speech can be synthesized from shorter speech units such as words and phrases. Moreover, the highway radio system updates messages every five minutes with high speed processing, and generates appropriate messages based on evaluation of the importance of collected information. This highway radio system has been working since November 1992 on the Tohoku Expressway and two other expressways.<<ETX>>","PeriodicalId":338322,"journal":{"name":"Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133660109","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}

It is presumed that upstream traffic volume can be used to predict the downstream traffic in a specific time period. Three models are developed for traffic flow prediction: a combination of historical average and upstream traffic, a combination of current traffic and upstream traffic, and a combination of all three variables. The three models were evaluated using regression analysis. The third model is found to provide the best prediction for the analyzed data. In order to balance the variables appropriately according to the present traffic condition, a heuristic adaptive weighting system is devised based on the relationships between the beginning period of prediction and the previous periods. The developed models were applied to 15-minute freeway data obtained by regular induction loop detectors. The prediction models were shown to be capable of producing reliable and accurate forecasts under congested traffic condition. The prediction systems perform better in the 15-minute range than in the ranges of 30- to 45-minute. It is also found that the combined models usually produce more consistent forecasts than the historical average.<<ETX>>","PeriodicalId":338322,"journal":{"name":"Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124929592","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}
