| Research Abstract |
This study provides the "Speedup Model on Intercity Railway in Japan", which can calculate the average velocity on each railway line, based on social benefit, railway operator's profit and improvement cost.
The model consists of four sub- models, that is, Transport Market sub-model, Technology-Velocity-sub-model, Technology-Cost sub-model, and Velocity-Benefit sub-model. In the Transport Market sub-model, we constructed a railway flow estimating model that can simulate both model choice and route choice. In the Technology-Velocity sub-model, we proposed an expression that can output the average velocity from a given technical option. The Technology-Cost sub-model outputs an improvement cost when a technical option is given. The Velocity-Benefit sub-model can calculate the user's benefit and the operator's profit under the given velocity.
Finally, the average velocity is determined through the whole model when OD flow, service level of all modes (railway, road traffic and air), and technical option of each line are given. Here, the technical option consist of vehicle's technique and infrastructure's technique whose level is selected by the rallway operator.
By applyint the model to the present network and the 2000-year network in Japan, we simulate the velocity level and the technical options in two cases : one is maximisation of railway operator's profit, and the other i maximisation of user's net benefit.
As a result of the simulation, we showed the optimal speed and technical options in both cases.
