In terms of development of intelligent information devices, the most important element is the function which is able to deliver the information user wants to input on the device without complexities. By using the mean such as our voice, expression, gesture and physical contact we use in our daily routine, we are able to interact with device easily and simply. In this paper, we are initiated to present interactive surface system, in which allows users to use their hand gesture as a function of mouse and keyboard free, to be interacted within the platform of management strategy simulation game we developed, ‘R-Day’.

지하도로는 폐쇄된 구조와 진출입의 제한성으로 인해 혼잡 발생 시 대응이 어렵다. 이에 본 연구는 혼잡 발생 가능성을 사전에 진단할 수 있는 정량 지표와 산정 절차를 개발하고, 시 뮬레이션 기반 교통제어 전략의 효과를 분석하였다. 테스트베드로 만덕-센텀 지하도로를 선정 하여 미시적 교통 시뮬레이션을 수행하였으므로, 소극적·적극적 제어 전략을 시나리오별로 적 용하였다. 분석 결과, 교통혼잡 판단 지표의 실시간 활용은 혼잡 발생 이전에 사전적 대응을 가능하게 하였으며, 제어 전략별 효과 차이를 정량적으로 확인하였다. 제안된 분석체계는 향후 지하도로 운영 및 관리에 활용 가능한 정량적 기반이 될 수 있다.

This study proposes a simulation-based framework for evaluating traffic management strategies in underground expressways. A congestion diagnosis index was developed using throughput and speed differential indicators, enabling early detection of potential congestion. A microscopic simulation of the Mandeok-Centum underground road was conducted to assess passive and active control strategies. Results show that passive control, such as detour guidance, can moderately reduce congestion risk, while active control achieves more immediate effects through access restrictions. The proposed index-based approach provides a practical tool for real-time traffic monitoring and preemptive management. It offers valuable insights for future operations, particularly once real traffic data become available after the facility opens.

The purpose of this paper is to develop a port simulation program for Inchon Port. The arrival and departure data from Inchon Port are analyzed, several probability density functions for the interval time and service time are estimated, and the berthing rules are constructed based on experts experiences. The port simulation program is written in visual basic considering the interarrival p.d.f., service rate p.d.f., berthing rules, and dual-dock system, and is used to analyze the effects of the changes in ship arrival rate and service rate upon the demurrage. It is expected that we can use the simulation results in order to prepare proper service level and to evaluate the appropriate investment strategy to be planned.
