Transportation is one of the industries that encounter the lowest improvement in the IoT. But this is about to change as we can already see it with smart cars, live stream information about the traffic, etc. With IoT, people are going to be able to access the internet all the times in cars, buses, trains, and planes. This is already happening, but it is not yet universal and it still needs some improvements.
IoT will make transportation also more efficient by giving customer real-time information on traffic, bus schedules, late trains, etc.. Transportation is one of the first steps to develop a smart city. Important security issues are not yet happening, but they will if we don’t act now with a proper strategical management of IoT.
