Outline of Final Research Achievements

This research aims to discuss the potential impact of recent development in information and communication technology on travel behavior and transportation project assessment by analyzing theoretically the value of business travel time saving and to derive the wage rate plus approach and Hensher’s formula from the models. Ten models are formulated based on three cases: the utility maximization of business traveler from an employee’s viewpoint, the profit maximization of the firm from an employer’s viewpoint, and the group utility maximization from the combined viewpoints of the employer and the employee. The results show that the wage rate plus approach is justified only in the employee’s utility maximization for the business travel that is made within work hours under the time off in lieu. Then, the Hensher approach is theoretically derived from the group utility maximization approach with additional assumptions. Finally the implications of the results are discussed.
