Abstract
Travel time reliability is a very important measure parameter of probability,which can effectively evaluate the dynamic(performance) of traffic system.On the basis of the concept of travel time reliability,the influence factors on travel time reliability on urban expressway are analyzed.The calculation method of travel time reliability of urban expressway based on Monte Carlo simulation is put(forward),that is using the method of Monte Carlo simulation stochastically samples the traffic demand variable of the entry of expressway,to calculate travel time, and check the calculated value.If it exceeds the threshold,it's unreliable.The proposed model is testified by a numerical example.Finally,the future application of travel time reliability as a probability parameter is proposed.
