Reliability Analysis Of Urban Road Network System By GO Methodology

The city structure results from the urban traffic network, which was essential for the sustainable development of city. And its reliability has extremely importance to insure the stability of traffic system. On the contrary, it will decreasing the effectiveness of other system while increasing the cost for maintain system else in city, which will lead to huge potential cost in the end. Such been the case, it has significant importance to study on the urban road network system. It should finally make out the reliability specification of the whole system through analyse each component of it for the urban traffic network system. Currently, Monte Carlo and Analytic are basically two way of operation for the reliability of the system. However, to apply for them are hard to do.GO is succeed–oriented analysis technique for the system probability, which is suitable for the reliability analysis of the complex system. It is begin with the input events, and work out the ultimate probability of the system after a calculation of the GO Model. The birth of GO is come from the theoretic of Decision tree. It's essence anamnesis is the translation through the system of schematic diagram, control diagram or engineering drawing according to certain rule. The method of building GO Map is that use GO Operator to replace the use of specific components and use signal flow directly connecting operator, the operator on behalf of certain functions, It has the operation rules with the input and output signal .Upon the setup of the GO diagram, the next step is to carry forward and finish the GO system in accordance with the guide of denotation of the GO, Hence, to work for the reliability analysis of the system. In this article, based on the process in general of analysis of the GO, it is analyzed systematically for the urban traffic network system and set up the GO diagram that in line with the urban traffic network system, To operate for the GO diagram and come out the reliability analysis of the system. This reliability analysis affords the theoretic for the system assessment, which have important significance for elevate the reliability of the present system.
