In Japan, mom than one alternate paths exist for many intercity OD pairs. This paper proposed amethod to evaluate improvements of rail/air network, considering alternate paths. In order tobuild the evaluation method, route choise model was estimated using modal split data, and gravity model was estimated using aggregated utilities of available routes for the OD pair. Rail/air network improvement was evaluated by consumer's surplus based on two models above. The method was applied to the following two network improvement senarios: Speed increase of Tokaido-Shinkansen and increase in the number of flights between maijor cities. Annual benefits for each pair of inter-regional passenngers were caluclated.
