Ⅳ. Results
1. Technology development of Mini-tram(PRT) Vehicle System
- Performance improvement of vehicle
Firstly, the existing supercapacitor was removed and a lithium ion / polymer battery was applied to increase the travel distance of the vehicle. In addition, the Charging Connector module was designed and manufactured to enable rapid wired charging.
In addition, the front / rear cover of air-cooled structure was designed and installed to compensate the inability of the front / rear cover of the vehicle to be air-cooled by the closed structure.
Finally, in order to solve the problem that the air conditioner does not start due to the lack of output power of the converter compared with the inrush current at the start of the air conditioner and the voltage drop at the input terminal of the inverter, capacitor (330mF * 4) Supplemented input power of the inverter solved the phenomenon that the air conditioner can not be started.

- Improvement of parts performance
Firstly, we developed and implemented a 6.5kW converter that can supply more stable vehicle power by reinforcing control power and service power in 5kW converter of existing vehicle. Since the existing converter only had DC output, it needed inverter to start the air conditioner and AC load device. However, since the newly developed converter outputs AC and DC power simultaneously, there is no need to install an inverter. In order to compensate for the deterioration due to the high temperature the newly developed converter adopts the structure that can cool the converter inside through the cooling fan to prevent deterioration due to the internal temperature rise.
Secondly, operation and communication part of MCU is improved by modification of MCU protocol.
Thirdly, to compensate for the deflection phenomenon caused by insufficient
stiffness of the existing suspension of the vehicle, height-adjustable suspensions were applied. In addition, the BCU and ECU of the vehicle were disassembled and checked to improve the braking response speed of the vehicle. Therefore, the BCU's internal wiring status check, the disassembly check and adjustment of the pressure sensor, the electric cylinder, and the motor, and the check of the appearance of the ECU and the check of the signal digital input / output state were completed.
Finally, LIDAR SERVER H/W was added. The LIDAR SERVER H/W is equipped with a power board, a SSD, a server board, a hub board, and a back board.

- Continuous automatic operation test
In the 5th year, we carried out a total of 15 car tests until December, with the goal of stabilizing the vehicle by multipath application. Algorithm was added and revised while driving test, and continuous stabilization test including control interlocking test using vehicle was carried out.

2. Development of high performance technology andn multi-functionaliation of advanced materials for railway infrastructure
- Development of PRT Central Operation System
Through the interface of PRT vehicle and 1: 1 wireless communication base, it manages the position and condition of all vehicles in real time. And it controls the vehicle's operation based on the dispatch request information generated from each stop, MA(Moiving Authority) method. In addition, in order to prevent collision between vehicles and to control the breaker at the intersection section, various kinds of technologies are necessary for commercialization such as on-schedule service, bidirectional operation control, platform management, Research and development.

- Development of PRT Simulation System
A checkerboard type route was designed in connection with the test route of the Korea Railroad Research Institute and a virtual test section with about 20 stops was built through modeling. The communication protocol used for the interface with the actual PRT vehicle was the same that we have developed a vehicle simulation engine that can be used in conjunction with a central control system at the same time as actual vehicle and virtual vehicle. And, the operation status of the vehicle can be monitored in real time through a 3D visualization module. Based on the operation history data, we constructed a user - defined reporting system to view KPIs

- Development of PRT Station Control System
Based on the operation method of the vehicle (on-demand, on-schedule), a system was created for passengers to request dispatching and boarding. In addition, a web-based system was built to enable dispatch requests via mobile apps as well as KIOSK.

3. Development of PRT Infra application and Vertical Trasportation Device
- Development on PRT Infra application
⦁ Review and survey for application target area considering with a purpose of establishment and future availability
⦁ Application target area Infra structure design has been studied witch based on Short distance traffic need in-city
⦁ Cost calculated about operating expenses and standard cost for installing the Infra on target area
- Development on PRT Vertical Transportation Device
⦁ Establishment of Manufacturing Standard for PRT Vertical Transportation Device
⦁ Establishment of Safety Standard for PRT Vertical Transportation Device

4. Development of Power Supply System for PRT
In the 5th year, The prototype vehicle’s Power Supply System establsihed the wireless charging type based on the Lithium Ion Capacitor was removed. and then, we supplemented the Power system by changing the wired plug type based on the lithium ion polymer battery to improve travel distance. when we made a wired plug charger, considering the compatibility about commercial electric-car charging methods. As a result, Although charging time was increased, improved travel distance could extend a applicability. In particular, PRT is easy to apply on the situational infrastructure.
