Daimler’s answer to traffic congestion is a high-tech spin on the lowly city bus.
The German automaker’s semi-autonomous bus—called the Mercedes-Benz Future Bus—made its first public journey on Monday along a 12-mile route dotted with tight turns, tunnels, and traffic lights between Amsterdam’s Schiphol airport and the town of Haarlem. The company called the successful navigation of the route a milestone on the road to autonomous city buses. Daimler did not reveal a timeline for when the bus might be adopted by the city’s mass transit authority.
Daimler sees urban transit as a more effective way to curb emissions and alleviate traffic gridlock in cities. The company took autonomous driving technology called Highway Pilot that it developed for its self-driving Mercedes-Benz Actros truck and modified it for city buses.
The technology, called CityPilot, captures data from nearly a dozen cameras, short-range radar, and GPS, and uses it to navigate a pre-determined route, recognize obstacles, and brake on its own when necessary. The software not only recognizes traffic lights, it can communicate with them to signal that they’re approaching—a handy feature that when used correctly could speed up travel times and reduces tailpipe emissions. The bus, which can reach a top speed of about 43 miles per hour, approaches stops automatically, and opens and closes its doors so passengers can go on and off.
There still are drivers at the wheel. Daimler says that drivers must only take control of the wheel when traffic regulations require it or when technology cannot handle the road conditions.
