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.Cost Benefit Analysis, Choice Experiment (CE) method, Monorail, Sensitive Analysis
