Cost Benefit Analysis on Public Transport Investment by Choice Experiment Method: An Example of Osaka Monorail Saito Linefs Extension (in Japanese)

The necessity of applying Cost Benefit Analysis (CBA) in evaluating the validity of a public transport investment is well recognized by policy makers in recent days. Originating in a sense of this fact, we implement CBA in a new project called Osaka Monorail Saito Linefs extension by applying a Choice Experiment (CE) method. It is estimated that the benefit cost (B/C) ratio is 1.87 under a basic scenario. In addition, with a consideration on different kinds of uncertainty in the future, a number of sensitivity analyses are implemented. The results of sensitivity analysis indicate that the possibility of generating net benefit is extremely high for the project studied here.
