This study proposes a simple practical method to evaluate the time-saving benefit of a transportation project. Evaluation theory have been developed by using the concept of the “Equivarent Variation”. This study, first, establishes a rigorous definition of the time-saving benefit based on EV. Second, through our “short-cut measurement method” it is shown that this theoretical concept of benefit can be expressed by the Marshallian transport demand function and post-improvement equilibrium prices. Finally, by using time series data from 1965 to 1980, this paper discusses its applicability by the case study on the time-saving benefit of a transport network formation.
