Then, the parking availability discriminator gathers the detection results from these image processors and decides the parking status for each of the small and large vehicle parking areas by the number of parked vehicles occupied in the areas being monitored.

According to the color features of road signs, we establish four heuristic decision rules: the range of the hue, the fixed order of the intensity of RGB, the ratio of the intensity of RGB, and the range of the intensity of RGB. Experimental results have achieved a 93.3% correct rate.

Differential global positioning system (DGPS) is one of the most practical navigation methods. This paper describes how to combine and/or fuse vehicle sensors to improve the position accuracy from the DGPS. The theoretical background for sensor fusion is the use of the Kalman filter. As an example of the proposed sensor fusion theory, we combine the optical gyro, wheel speed measurements that may include high frequency noises and the DGPS signal which, due to circumstances, is frequently suffers interference. Validity of the method was examined by a real automobile in real circumstances.<<ETX>>","PeriodicalId":338322,"journal":{"name":"Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference","volume":"37 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":"131593684","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 National Police Agency, Japan (NPA), which governs the Japanese traffic management, has been promoting to introduce an advanced traffic management system called UTMS. UTMS is based on a broader concept like the IVHS in the United States and the DRIVE in Europe. From the viewpoint of traffic control using an automatic control system, this paper deals with four categories: the optimum control of the signal control system, the traffic information service system, the advanced traffic control system supported by a traffic data acquisition system, and the goal of UTMS.<<ETX>>","PeriodicalId":338322,"journal":{"name":"Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference","volume":"10 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":"131936511","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}

A research team, encompassing research institute, university and electronic company, conducted the three-year project for developing the new system, named TRACS (TRaffic Adaptive Control System). The project was successfully completed in 1994. TRACS aims at accomplishing the objectives of better traffic adaptability and more reliable travel time prediction. TRACS operates in real-time adjusting signal timings throughout the system in response to variations in traffic demand and system capacity. The purpose of TRACS is to control traffic on an area basis rather than an individual uncoordinated intersection basis. Another purpose of TRACS is to provide real-time road traffic information such as volume, speed, delay, travel time and so on. The performance of the first version of TRACS was compared to the conventional TOD control through a field test. The test result was promising in that TRACS consistently outperformed the conventional control method. The change of signal timing reacted timely to the variation of traffic demand. The feature of real-time travel-time estimation is under study.<<ETX>>","PeriodicalId":338322,"journal":{"name":"Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference","volume":"10 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":"130787869","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}
