Research On The Analysis Method Of Connectivity Reliability In Transport Network Of Events

In this paper, we have defined the reliability of the connectivity is that in the traffic network, it is a probability, which any more OD pairs keep the road in good condition in the period of time. Now, the research of the reliability has became a focus. As deepening as research, it has applied in the research of the reliability of network connectivity, and the reliability of the network of events. To analysis the reliability, can describe the system operating state during a given period, forecast condition of it in the future and possibility of blocking and delay effectively, but also can evaluated situation of run of the actual network. In this paper, the method we used could reduce the difficulty of the calculation, increase the accuracy of the results, and provide a more and more reasonable method for the management and planning of traffic network about the events.Firstly, in this paper we defined the events, analysis the features of the traffic demand and flow about the events, then gave the definition of the reliability of network connectivity. Based on it, we made clear to the objective, content, significance, method, the ideas of research and innovation of this paper so on. Then, we summed up the method of research about the reliability of network connectivity of events in the home and abroad, and estimated the advantages and disadvantages of old methods, then, pointed out the method in this paper.What's more, it reveals the function of the reliability of network connectivity about dividing the unit of path, the effect of it about the volume of traffic, capacity, and road conditions; and it identified that we estimated the reliability is high or not used by saturation. Then, we elaborated how to demarcate the reliability of the unit in the network of traffic.Then, in this paper, describes the method of the reliability of network connectivity, decided that the method of dividing scope of influence of traffic events. The method reduced difficult of analysis about it, and elaborated how to deal with the effect of the reliability of network connectivity about intersection, then decided the method of analysis about.Last but not least, we took the 10th china athletic meeting traffic management as an example. We have collected data of researching, and used the above research methods. In this paper, calculated the reliability of network connectivity, test and verified the applicability and feasibility of this method. Then, brought a new idea in the research of reliability, and the calculated results have practical value.
