Technology and Aerodynamics
‘‘ There is a project in Canada that is aiming to make crossing railway tracks for commercial vehicles perfectly safe. The vision here is to have the signal mechanism at every rail crossing emit a radio signal that will be recognized by the truck’s computer and then give an audible warning to the driver there is a train about to cross the road. If the driver doesn’t react in a specified amount of time, then the truck itself applies the brakes so the truck stops well short of the tracks preventing a truck train collision. Yes, this is just in the idea stage. The final product may not look or act like what is described here, but there is thinking going on to prevent truck train collisions of which in Canada there are some 40 per year. In the US, the number is significantly more. Computer and camera technology is going to be a much larger part of the driving experience as time goes by. In one person’s lifetime we will have gone from trucks that were little more than buckboards with engines that were difficult to manage; hard to steer; under powered; and slow to complicated machines that are more computer than truck and needing little or no moni10
