It is very difficult to find optimal train operation plan when analyzing the economic investment using traditional railroad travel demand estimation method. Train operation plan depends on travel demand and vice versa. To solve this problem, this study suggests a demand estimation method to address an optimal train operation scheme with the modal spilt using initial train operation plan and trip assignment.

The safety, serviceability, and design code of the infrastructures such as highway, railroad, bridges, etc. have been analyzed. It is identified that the safety and function of infrastructures in North Korea could have some problems compared with current design codes. After analyzing the results, the multi-step road map for integrating infrastructures in Korea Peninsula is proposed.

Most of real world systems are highly non-linear. But due to difficulties in analyzing and dealing with it, only the linear system theory is well estabilished. Bilinear system where state and control are linear but not linear jointly is introduced. Here shows that optimal state estimation of stochastic bilinear system requirs infinite dimensional filter, thus onesub-optimal estimator for this system is suggested.
