Smart station is a modular one easily installed on the road and protecting from the environmental effects such as snow and rain etc. Smart station can provide some comfortable and easy ambience during waiting the Bimodal Tram. Conventional station can be invaded by overdriven vehicle to make some fatal accident. But smart station gives more protective and safe shelter to the passengers. This paper have investigated and analyzed the structural safety and usefulness about the new conceptual modular smart station.

General bus stop is very simple and have some problem to protect the passengers and don't have any proper information messenger for the convenience of bus riding in spite of present initiative bus information system. However, this paper have introduced new conceptual modular-smart station avaliable to both public bus and bimodal tram. It can secure the passenger's safety from other danger attributes like running car or unexpected natural disaster and supply the passengers the variable information from display which is connected to the control center. Therefore, modular-smart station is both shelter and information messenger for passenger's safey and convenience.

Light weight of vehicles by composite materials makes possible high speed, energy saving, and low repair cost. As Bimodal Tram and Tilting Train eXpress(TTX) use carbon composite material for their bodies, safety for passengers and electrical devices against unexpected failures has been issued more than ever. Lightning strike which generates high voltages and large currents is the worst case for the safety of passengers and devices. With this background, we experimentally investigated the insulation breakdown phenomena on carbon composite materials by the application of lightning surge voltage and current. From the experimental results, we could estimate whether the composite body is safe or not for the inside passengers and devices against lightning strikes.

Newly developed Series hybrid low-floor articulated vehicle which can meet both road and railway running conditions. It has the rated driving speed of 80 km/h and three driving modes with hybrid(engine+battery) driving mode, engine driving mode, battery driving mode. The battery driving mode requires the several 10 km running without additional charging operation. The vehicle has been equipped with LPB (lithium polymer battery) pack for the series hybrid propulsion system. LPB pack consists of 168 cells (3.7 V in a cell, 80 Ah) in series, DC Circuit breaker, mechanical rack, BMS (battery management system). This paper has shown the design process of LPB pack and application to the vehicle. Driving results in the road was successful to be satisfied with the requirement of the series hybrid vehicle.

기차나 군용 트럭 등에 이용되던 굴절차량이 승객의 대량 수송을 위하여 일반 도로에 적용이 검토되고 있다. 레일을 따라가지 않고 일반 도로에서 주행하는 굴절차량은 회전반경, 차량 선회 폭, 이탈궤적, 스윙아웃등 다양한 제어 요소를 갖는다. 현재 승객 수송을 목적으로 제작되는 굴절차량은 각 바퀴에 하나의 모터를 장착하고 구동하는 독립 구동 방식을 채택하고 있으며, 각 바퀴의 독립 제어를 통하여 차량의 빠르고 정확한 자세제어가 가능하다. 이 논문에서는 여러 제어 요소 중 굴절차량의 최초 목적인 회전반경 감소를 위한 토크 분배 알고리즘을 제안하고, 시뮬레이션을 통하여 회전 반경이 감소함을 검증하였다.
