There are many ticket gates at the subway station. The managers are quite careful about the load degree of the ticket gates. This paper studies two different methods to calculate the load degree of the ticket gates. One is based on the station ticket gates group as the research object, and the other one is based on the volume of passenger flow passing in and out of the station as the research object. Then we use the data investigated at Chaoyangmen station in Beijing to test and verify both of the methods. At last, we can get the conclusion that we can get the same result by the two methods, but the method of based on the volume of passenger flow passing in and out of the station is more reasonable.

In realization of interoperation process of inter-provincial interconnection charges security management and highway emergency response and service systems, breadth-first interoperation, depth-first interoperation and mixed interoperation are widely used. This paper gives a brief introduction of these three methods. And for breadth-first interoperation, gives the example of authentication that used in the real system. At last, for mixed interoperation, the cost function and the steps in realization is talked about.

Development of the railway information and intelligent systems has been progressing greatly but in isolation, research on interoperation with information system would solve existing problems in informatization of railway. Through research of construction status of railway information system in china and requirements analysis of interoperability system, we design and build the railway emergency rescue command system and give the hierarchical structure and logical structure of the system.

Due to the analysis and research the of the Traffic Safety Management, faced with the problems of scattered business application systems, fully integrated business data resources and inter-departmental information sharing, and based on the existed OBAC Access Control Model, this study has proposed a dynamic trust-based information systems interoperable access control technology, provided technical support to solve the interoperability of information between inter-departmental access.
