Abstract

The Personal Rapid Transit(PRT) system has been highly interested in future transportation developments due to its on-demand and optimized door-to-door transport capability. However, the major impediments to the commercialization of PRT are the high cost for construction of infrastructures as opposed to the small transport capacity and difficulty in defining the role of PRT in building a balanced transportation system. In this study, the vertical transfer device for the PRT vehicle is developed to provide more flexible and better compatible urban mobility services between means of transportation, which is expected to meet particular demands in a particular environment. This apparatus was initially designed based on the basis of vertical circulating conveyors with steel chains, which is frequently used in logistics. Its advantages are capable of the non-stop loading and reduced head-way time. Most importantly, it was intensified by the additional idea to ensure the stable and reliable transfer of the PRT vehicle fully loaded with passengers. The 1/10-scale prototype was successfully tested to demonstrate a fundamental mechanism of vertical transfer and identify unexpected user requirements prior to a real manufacturing process.

수요응답형 순환교통시스템(Personal Rapid Transit: PRT)은 자동차에 버금가는 승객의 요구 대응성 및 최적경로 운행으로 인한 높은 효율성 등의 특징 때문에 미래형 신교통수단으로서 많은 주목을 받아 왔다. 하지만 수송 분담 능력(4~6명)에 비해 건설비가 많이 들어가고 기존에 운용되고 있는 타 대중교통시스템과의 역할 분담 문제 때문에 적용에 한계가 있는 것도 사실이다. 따라서 본 연구에서는 도시 내 유연한 운용과 타 교통수단과의 연계를 목적으로 PRT 차량을 위한 수직이송장치를 개발하였다. 기존의 물류 분야에서 많이 채택되고 있는 순환 컨베이어 방식을 응용하였으며, 특히 연속이송이 가능하며 사이클 타임이 적은 장점이 있다. 이와 더불어 1/10 스케일의 모형의 제작을 통하여 장치의 기술적인 운용 가능성을 확인하였으며, 이를 통해 구조적 안정성을 확보하기 위한 방안을 도출하였다.
