Study On Automatical Estimation And Implementation Of Traffic Joint Rationality Fot Railway Passenger Station

Railway is crucial mode of urban external transportation and at the same time, it also is the connection of urban traffic network of all sorts of modes, and the passenger flow distributed and transfered places.Because of a high degree of safety, high speed, low fares and small affect to the bad weather, Railway transportation has the most advantages in long distance travel for passengers, with the spurt growth of city size and population, the situation of urban road traffic jams has increasingly manifested itselt. Railway passenger transport hub is the key nodes of city traffic and the though traffic of a city, therefore, rational joint is necessary condition to ensure orderly joint between urban external and inner transportation.Based on rationality of automatically estimation of urban railway passenger transport hub and urban road traffic as the research object, the fuzzy identification method of database technology is put forward in this paper. Through analyzing the basic function of railway passenger transport hub, this paper began from urban railway passenger station and urban road traffic, discussed respectively concept and feature of this parts, then made a research of the mechanism in joint between the two parts and analyzed the joint modes and features. Rendered the concept and significant about rational joint, then summarized and abstracted rational joint effect factors.Trigger mechanism is the key to realizing the initiatives of active database. This study adopts the standard SQL modules, on basises of analyzing the information database of reasonable discriminant, the rational discrimination and quantitative index are put forward. Combining the fuzzy database theory, establish the fuzzy relation data model, and by using the SQL Server2005to establish database tables. Through the trigger program design and programming of c#to realize the function of rationality of integration automatically estimation. Take the Wuchang railway station as an example to show the validity of this method of this study.
