The Swedish-Israeli start-up company, Road-Guard, impressed the Bavarian jury in the European Satellite Navigation Competition (ESNC) 2008 with their ‘GreenDrive’, a mobile phone-based ’guide’ about ecological driving and obtained second place overall. The ‘Horizon Prediction’ technology patented by Road-Guard founders Alex Ackerman, here seen left in photo, and Yossef Shiri, right, predicts the routes ahead and recommends to the driver the most economical speed in each case within the given speed limit. The objective of this mobile driver assistant system is to minimise the influence of the driving style on fuel consumption and thus to reduce consumption by 15-25 percent.
