Developed for the government by the Netherlands Organization for Applied Scientific Research (TNO), the intelligent bicycle, runs on electricity. A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1, 700 to 3, 200 euros per bicycle. The devices on the bike are linked through an onboard computer with a vibrating (震动的) warning system fitted in the bicycle's saddle and handlebars to warn cyclists of the coming danger. The saddle vibrates when other cyclists approach from behind, while, the handlebars do the same when barriers appear ahead. "Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed," said Maurice Kwakkernaat, one of TNO's research scientists involved in the project. "The onboard system technology has already been at work in the car industry," he said. ''More and more elderly people are using a bicycle, not only for short distances, but also for longer distances," Dutch Environment and Infrastructure Minister Melanie Schultz van Haegen told AFP. "This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue to enjoy cycling," she said. |
