Most of the railway traffic control systems are using in the DBMS(Database Management System)is a disk-based DBMS. When the train schedule and the event data is inputted and referred at real time on Disk-based DBMS it is characteristic of the slow access time and the data is preserved permanently. For this reason this paper suggests the way of improving for Railway Traffic Control System by the hybrid DBMS using a combination of memory and disk. We apply the Hybrid DBMS to Railway Traffic Control System and compare the existing method with suggested one using the same data. As a result of comparison we have come to the conclusion that suggested method is far more performance to shorten data access time and process a mass information than the previous methods.

The primary purpose of the safety management is to prevent the loss of lives or physical damages arising from potential hazards in the railway signaling system. Since such potential hazards may occur at any time during the system life-cycle from design and development to maintenance safety management activities have to be continuously taken in the course of the system life-cycle. In this paper presented for Safety Activity Process. (Phase Methods Documentation)
