Korea demonstrates the future of EV transport

The city of Gumi, South Korea is proving that solutions for future energy and transportation problems are happening now, with the online electric vehicle (OLEV), developed by the Korea Advanced Institute of Science and Technology (7443 KAIST).

OLEV is an electric vehicle that can be charged while stationary or driving, removing the need to stop at a charging station, nor does an OLEV tram require pantographs to feed power from electric wires strung above the tram route.

OLEV receives power wirelessly through the application of the shaped magnetic field in resonance (SMFIR) technology, a new technology introduced by KAIST that enables electric vehicles to transfer electricity wirelessly from the road surface while moving. Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. A receiving device installed on the underbody of the OLEV converts these fields into electricity.

Following the development and operation of commercialised OLEV trams at an amusement park in Seoul and shuttle buses on the KAIST campus, the city of Gumi is providing an OLEV public transportation service, using two OLEV buses on a 24 kilometre inner city route

Dong-Ho Cho, a professor of the electrical engineering and the director of the Center for Wireless Power Transfer Technology Business Development at KAIST, said: "It's quite remarkable that we succeeded with the OLEV project so that buses are offering public transportation services to passengers. This is certainly a turning point for OLEV to become more commercialised and widely accepted for mass transportation in our daily living."

After the successful operation of the two OLEV buses by the end of this year, Gumi City plans to provide ten more such buses by 2015.

    Future traffic management needs new thinking, new technology
    One of the biggest problems facing US ITS professionals, says Georgia DOT's Hugh Colton, is the constrained thinking which is sometimes forced upon those making procurement decisions. It is time, he says, to look again at how we do things. In the November/December 2010 edition of this journal, Pete Goldin interviewed Joseph Sussman, chairman of the US's ITS Program Advisory Committee. Amongst other observations that Sussman made was that, technologically, ITS in the US is 10 years behind that in the world-l

    David Crawford investigates the potential of new projection technology. Fifty years on from its invention of the microchip, US company Texas Instruments (TI) has compressed the technology into a surface area of just 4.3mm. As such, it forms the heart of a new Pico Digital Light Processing (DLP) system that is set to transform travel information delivery for millions of users on the move - by making it projectable.

    David Crawford explores a high-level option of public transport. Sharing its origin with that of ski lifts at winter sports resorts in the European Alps, urban aerial cable transport is attracting growing interest as a low-footprint, low-energy alternative to conventional public transport that can swoop over ground-level traffic congestion.

    Ford, MIT project measures pedestrian traffic, predict demand for electric shuttles
    Ford Motor Company and the Massachusetts Institute of Technology are collaborating on a new research project that measures how pedestrians move in urban areas to improve certain public transportation services, such as ride-hailing and point-to-point shuttles services. The project will introduce a fleet of on-demand electric vehicle shuttles that operate on both city roads and campus walkways on the university’s campus. The vehicles use LiDAR sensors and cameras to measure pedestrian flow, which ultimate
