Paper, 2002Description: 10 sSubject(s): Bibl.nr: VTI 2002.0071Location: Abstract: Japan sees heavy winter snowfall in the northeast and rainy summer typhoons in the west, both of which seriously affect road and traffic conditions. Such climatic circumstances make road traffic information provision to drivers important. J-System of the Japan Road Traffic Information Center (JARTIC) provides accurate online road traffic information in real time to road users. J-System is advantageous in that information service providers can easily tailor the provided information to fit their media . Information of J-System that started operation in December 1999 is available via Internet, mobile phone with an Internet protocol address, and television stations etc. It was being used by 30 information service businesses and about 300, 000 end users as of June 2001. J-System's basic data processing includes transforming VICS code information into text format to show an object with a specific route name, direction, and location. J-System prepares three typical data formats that can be used for various media. For information display, three formats are available: text only format, text plus kana (a phonetic Japanese syllabary) format, and simple graphics format. This paper reports the significance of road and traffic information provision in Japan, which experiences localized heavy snowfall and rain, the mechanism and utilization status of J-System for online traffic information provision, and its charge system.
