Increased economic activities and improvements in quality of life have resulted in a corresponding increase in human and material traffic across existing transport networks. Hence, there is a need for examining the reliability of these networks. The main objective of this study is to examine travel time reliability of various sections in the Han-Shin expressway network Osaka and Kobe area. Performed travel time reliability evaluation of each route considered in this study. To do this, various existing travel time reliability indices are considered and are examined. The advantage of travel time reliability is that, it can be used in policy assessment as a new evaluation technique and also may be used as travel time related information to the system users. Further in this study, conventional congestion measures presently using a measuring performance of Han-shin expressway network are compared with travel time reliability measures. Results reveal that reliability measures are more capable of measuring the variability in congestion level.
