The potential sources of disruption to transportation network are numerous and little has been accounted for the variability on traffic state, especially travel time. Based on statistics methods, three-hierarchy framework of assessment on travel time reliability is proposed in this paper to show the ability of transportation network dealing with uncertainty and satisfy the requirement of road users. The variability of travel time can be obtained by taking the spatial and temporal distribution characters into consideration. A practical application is executed to verify the utilization of travel time reliability and the travel time reliability under practical scenario can be estimated.
