As the world's urban centers grow, getting around them becomes increasingly difficult. In some cities, traffic is congested all day long and rush hour can last for several hours. Fortunately, there are a number of innovations in public transportation specifically aimed at alleviating those woes. While traditional buses simply add to street traffic and subways aren't feasible in all areas, engineers are looking to public transit options that can go over or around regular car traffic, making for some easier ways to get from Point A to Point B without spending hours sniffing exhaust. Elsewhere in the world, underwater floating tunnels will reduce the need for ferry rides, and a unique modular transport system could completely revolutionize long-distance travel for both people and cargo. Read on for all the details about the next generation of transportation, including some developments that will be up and running in less than five years.
