![]() We’ve spun the project out as a company, called Virtual Traffic Lights (VTL), and we’ve tested it extensively in simulations and, since May 2017, in a private project on roads near the Carnegie Mellon campus. ![]() The algorithm allows cars to collaborate, using their onboard communications capabilities, to keep traffic flowing smoothly and safely without the use of any traffic lights whatsoever. Then there’s the Internet of Things, which promises to connect not merely the world’s 7 billion people but also another 30 billion sensors and gadgets.Īll of these technologies can be made to work together with an algorithm my colleagues and I have developed at Carnegie Mellon University, in Pittsburgh. Another emerging technology is that of the autonomous vehicle, which by its nature should minimize commuting time (while making that time more productive into the bargain). It’s often called vehicle-to-vehicle (V2V) technology, although this linking can also include road signals and other infrastructure. ![]() One of them is the wireless linking of vehicles. Take heart, beleaguered commuters, because such a system has already been designed, based on several emerging technologies. That’s enough to save 22 hours a month, which over a 35-year career comes to more than 3 years. Now suppose we could develop a system that would reduce a two-way daily commute time by a third, say, from 3 to 2 hours a day.
