영어로 써 주시면 감사하겠습니다...

논문 초록을 작성하려고 하는데....영어를 좀 못해서여...있는 내공 다 드릴테니..

 

신경써서 작성해 주시면 정말 감사 드리겠습니다..꼭 좀 부탁드리겠습니다..

 

 

 

 

PRT(Personal Rapid Transit)는 Personal란 용어에서 알 수 있듯이 한량 당 2~6명 정도의 인원을 수송하는 개별적 교통시스템을 말하며 정해진 특정 노선이 없어, 이용자가 목적지를 선택하면 중간 정차나 환승 없이 목적지 도착이 가능하다. 따라서 노선이 정해진 시스템이라는 약점을 안고 있는 기존의 중·대형 대중교통수단의 문제점을 PRT는 훌륭하게 보완할 수 있다. 차량은 전기로 움직여 배기가스가 전혀 없어 환경 친화적이고, 경량의 차량은 건축비를 절감시킨다. 또한 좁은 선로는 다른 교통수단과의 연계를 쉽게 해주고, 세련된 건축이 가능해 도시미관과 잘 어우러진다. 이와 같이 PRT는 뛰어난 접근성과 함께 대중교통과 자동차의 장점을 모두 가지고 있어, 앞으로 PRT가 활성화 된다면 우리나라 교통체계에 커다란 변화를 일으킬 것이다. 본 논문에서는 PRT의 장점과 해결해야 할 문제점, 그리고 현재 진행 중인 철도 선진국의 사례를 분석하고, 앞으로 PRT가 우리나라에 정착하기 위해 필요한 방안에 대해 검토하고자 한다.

    The vehicles of Personal Rapid Transit (PRT, also called "podcars"), as known by the term of "Personal", an individual transportation system that each vehicle can seat and carry two to six people,  wait for users at each station, without a specifically set route, ready to take users non-stop, directly to his or her destination.

     

    Once users get in and select , he or she go straight to his or her destination, without halfway stops and transfers.

     

    The theory of the PRT approach is that users can be custom-routed from where they are, to precisely where they need to go. A passenger would just summon a personal robot pod (vehicle) and has it routed straight to his or her destination. Namely, users PRT vehicle bypasse all the stations along the way.


     

    All vehicles are eco-friendly and powered by electricy.  The lightweight little cars help the railroad construction cut costs.

     

    (Namely, the lightweight little cars (in many designs, using variants of automotive technology) would almost surely cost less than heavier, fullsize railcars. More importantly, the elevated guideways would supposedly be much cheaper because they wouldn't have to support as much weight. Furthermore, the little elevated stations would be expected to be smaller and significantly cheaper.)

     

     Because most mass transit systems move people in groups over scheduled routes, which have certain inherent inefficiencies, PRT can be well used to supplement a mass transit service.

     

    Also, narrow railroads make it easier connections with other transportations. Fine consturctions go well with the glamorous townscape.

     

    Thus,  PRT has its virtues of excellent access, public transportation and automobiles. In future, the revitalization of PRT will produce a great transformation in our transportation system.

     

    After this paper is to analyze the advantage of PRT, some of the problems we must solve, and the railroad case of advanced countries, our study is to examine the necessary plans to establish PRT in Korea.

     

     

     

     

     

     

     

    Comparison of Personal Rapid Transit with existing transport systems
    Similar to automobiles
    • Vehicles are small—typically two to six passengers Vehicles are individually hired, like taxis, and shared only with the passengers of one's choosing Vehicles travel along a network of guideways, much like a network of streets. Travel is point-to-point, with no intermediate stops or transfers Potential for on-demand, around-the-clock availability Stops are designed to be off the main guideway, allowing through traffic to bypass stations unimpeded
    Similar to trams, buses, and monorails
    • A public amenity (although not necessarily publicly owned), shared by multiple users Reduced local pollution (electric powered) Passengers embark and disembark at discrete stations, analogous to bus stops or taxi stands

    Likewise, PRT promoters predict amazingly low operating costs, mainly because of automated, driverless operation.

     

    [2] 따라서 노선이 정해진 시스템이라는 약점을 안고 있는 기존의 중·대형 대중교통수단의 문제점을 PRT는 훌륭하게 보완할 수 있다.

     PRT could be well used to supplement a mass transit service, which have a serious disadvantage of a set route system.

    Perhaps most importantly, PRT systems offer a more viable long term alternative to cars because they too offer privacy and the ability to choose one's own schedule.[3] Such a system may in fact allow for quicker transportation than cars in some contexts, considering that automated vehicles avoid slowing unnecessarily.

    All current designs are powered by electricity. In order to reduce vehicle weight, power is generally transmitted via lineside conductors rather than using on-board batteries.

    And it would all be incredibly cheap, we were told: "To build a metropolitan PRT system, the tag would be on the order of $4 million per two-way mile, according to recent cost analyses" gushed Popular Science. Compared to $27 to $50 million a mile – the price for "advanced" rail systems and subways, according to the magazine – "personal rapid transit looks like a bargain." (All figures in US dollars.)

    in contrast, LRT may lack some of the glamorous gadgetry, but it does offer a long, proven track record as a transit mode that works well, that is affordable and cost-effective, that excites the public and attracts passengers, that has proven its ability to reliably handle large volumes of riders, and that stimulates adjacent transit-oriented development. Planners and decisionmakers need to decide: Which are they going to believe – computer simulations, or the real-world evidence before their own eyes?
