Bimodal tram with the hybrid propulsion and low floor is a new and beneficial vehicle for the public transportation which is good for both the convenience of the weakness and the prevention of the green house effect. Bimodal tram consists of a complicate electrical and mechanical systems. Each system does not operate with independent but with cooperative. So, we need a synthetic control management system for managing all system effectively. This paper has investigated the configuration and functions of VCU(Vehicle Control Unit) installed inside of bimodal tram which plays variable roles including the apparatus control and the condition monitoring.

Bimodal trams are run by a guidance system and combine the functions of buses and trains. The trams have been highlighted as an alternative means of public transportation due to their accessibility, mobility, and arrival accuracy. While bimodal trams can be implemented on existing roads or by road expansion, with the narrow road conditions in Korea, studies must be performed in advance on suitable lane and platform locations and the exclusivity of lane use. This paper proposes plans for the location of bimodal tram lanes and platforms, whether in the median or at the road’s edge. In addition, methods of efficient bimodal tram operation are discussed, including the implementation of exclusive tram lanes.

The status and effectiveness of Bi-modal Tram is analyzed through the comparison of the transport effectiveness and operation cost between the public transportation systems (bus, light rail transit) considering the vehicle and operation characteristic of new transit system Bi-modal Tram. The standard operation schedule is established in consideration of the vehicle specification and operation characteristic of main public transportation modes, and then the annual average operation cost is estimated depending on the volume, speed, analysis length for respective public transportation mode. Through analyzing the operation cost and distribution characteristic of public transportation modes depending on the transport volume and travel speed, the operational efficiency suitable for the city is derived. It is concluded that the operational efficiency of Bi-modal Tram is superior to that of the bus and light rail transit on the aspect of travel volume and operation speed.

Bimodal Tram is the newly developed vehicle for both the tracked way and the public road. Its operation system has some characteristics including BIS(bus information system)/BMS(bus management system) based on ITS(intelligent Transportation system) which is used presently in public transportation operation system. One of them is more accurate vehicle fleet control based on both magnetic maker position reference system and GPS(global positioning system) and the other is automatic vehicle control for emergency situations by the Bimodal Tram operation system which will be performed by the unified control and operation center. This paper has investigated the requirements and functional definitions necessary to construct the unified control and operation center for Bimodal Tram operation system which will be more efficient and secure public transportation system than the conventional ones.

The free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) and deep inferior epigastric perforator (DIEP) flaps involve transferring skin and subcutaneous tissue from the lower abdominal area and have many features that make them well suited for breast reconstruction. The robust blood supply of the free flap reduces the risk of fat necrosis and also enables aggressive shaping of the flap for breast reconstruction to optimize the aesthetic outcome. In addition, the free MS-TRAM flap and DIEP flap require minimal donor-site sacrifice in most cases. With proper patient selection and safe surgical technique, the free MS-TRAM flap and DIEP flap can transfer the lower abdominal skin and subcutaneous tissue to provide an aesthetically pleasing breast reconstruction with minimal donor-site morbidity.

The public transportation in operation or to be planned domestically includes subway, LRT, bimodal tram and bus, which are independently characterized in their passenger capacity and cost. High quality service is generally accompanied by high cost of construction and operation. Thus, ITS, BIS/BMS and BRT system are recently introduced to provide high quality service to the passengers with the cost as low as possible. The bimodal tram is under development to achieve such goals in public transportation. The passenger capacity is approximately expected to be 10,000$\sim$17,000 persons/hour and the construction cost to be 10$\sim$30 million dollars/km. It is possible to construct the infrastructure gradually depending on the demand of transportation in the planned route, which can effectively reduce the initial cost to launch the service. The bimodal tram is developed to provide the advantages of subway and bus to the passengers with respect to the scheduled operation and flexibility of the lines.

This paper discusses about the implementation of a simulator for the Navigation Control System(NCS) of bimodal tram. To operate a NCS of bimodal tram, values of all sorts of sensors installed in bimodal tram should be transmitted to the NCS, and the NCS calculates the measured sensor values to determine traveling direction, traveling speed, current position etc. The implementation of the simulator consists of a device applying driver's input transaction function & virtual sensor program and a sub-rack device that controls communication with the NCS to evaluate navigation control function. The virtual sensor program can create routes (map), traveling profiles & seat information et cetera in order to transmit to the NCS, analyzes driver's input values and NCS output values to create virtual sensor values. The sub-rack device takes charge of communication with the NCS using CAN-OPEN, CAN-J1939, MVP protocols. This paper discusses about the implementation of the simulator and afterwards analyzes and evaluates the NCS simulation results.

Bimodal Tram is a new public transportation system combined subway with bus and consists of variable electric equipment to accomplish the comfortness, reliability, safety and so on. One of them is VCU(Vehicle Control Unit) for Performing driver's cmmand and monitoring the state of other equipment. To lessen the wiring and the interference of outer electromagnetic noises is very important things for bimodal tram with complicated configuration of electric equipments. This paper has investigated the application of CAN(Controller Area Network) communication method for VCU which has display, central unit and several nodes that are connected with other electric equipments(HVAC, door controller etc). We designed and manufactured the prototype of VCU which eventually will be installed on bimodal tram being developed in KRRI at present.
