전용의 궤도에서 무인자동으로 승객의 요구에 따라 출발지에서 목적지까지 최적의 경로로 논스톱으로 운행하며, 높은 시스템 접근성과 프라이버시 보장 등 승용차 수준의 서비스 제공이 가능한 대중교통수단인 PRT의 운행관리를 위해 3D 그래픽 기반의 중앙제어 시스템을 개발하였다. PRT는 정거장을 필요에 따라 본선 또는 측선으로 설치가 가능하며, 승객의 요청에 따라 배차서비스를 수요에 탄력적으로 대응할 수 있다. 본 연구에서는 PRT 차량의 운행상황을 직관적으로 모니터링하기 위해 3D 그래픽 기반 운영제어 시스템을 개발하였으며, 승객이 요청한 차량이 정확하게 배차되어 탑승하였는지 확인하기 위한 운행 보조 시스템을 설계하였다.

The PRT(Personal Rapid Transit) in material or immaterial guided tracks is operated automatically according to the needs of passengers with the optimal non-stop path from the source to the destination. In recent years, the personal rapid transit (PRT) system, which affords superior accessibility and ease of use, has been spotlighted as a new transport system for the future. In this study, a method for vertical lifting of PRT vehicles was proposed to facilitate interlink with other means of transport and thereby improve the efficiency of door-to-door transport. For this purpose, operation control interfaces were designed and experiments were conducted. Programmable Logic Controller (PLC) dedicated for the PRT vertical lift was designed to interface with Operation Control Center (OCC) by Modbus TCP over Ethernet. We implemented a 3D graphical PRT operation simulator which can emulate the mixing operation of the virtual vehicles and the actual vehicles.

In this paper, we propose the EPTS(Emergency vehicle Priority Transit system) for a rapid drive or emergency vehicles at the crossroads. The EPTS is one part of real-time traffic management system in the advanced traffic management system. The EPTS needs the connection or a traffic control system and a DSRC system. It can be applied to the real traffic situation considered with other traffic elements. As the result it is possible for the EPTS to nonstop drive because it induces an efficient drive of emergency vehicles. It is also relatively safe at the crossroad, it is expected that the EPTS is suitable for a telematics service which values efficiency above everything else.
