Abstract

 These days, providing reliable road transportation services is required. The reliability of road transportation can be classified into connectivity reliability, travel time reliability and safety/comfort reliability according to required functions. The trav el time reliability is concerned in this study. The variability of traffic flow and travel time is review ed, and travel time reliability indices proposed in previous studies and their properties are organized. Trav el behavior models with travel time reliability are classified, and the value of travel time reliability is examined based on the estimation results of the models. Then, a method for travel time reliability benefit is proposed. This would be helpful for cost-benefit analysis with reliability or road tr affic management which increases the reliability.
