The Bayesian network in the traffic network failure degree approach is aplled in a creative way. By using the method of empirical study,the traffic network failure degree approach is researched based on Bayesian network with the evaluation index of connectivity reliability.The method of the traffic network failure degree quantification is concluded based on Bayesian network by analysising the cause of traffic network failure,establishing the event tree and fault tree and then buliding the Bayesian network with the algorithm of transforming event tree and fault tree to Bayesian network.Finally,a simple example of the road network is cited,according to the above-mentioned method,establish the Bayesian network of road network failure and use the software MSNBX to simulate the different types of attacks,then got the result to prove the validity of the method that had been mentioned and given some advise to the application of bayesian network in research on large scale traffic network.
