Take Amsterdam, for example: signals from special traffic lights light up ahead of the bus. Two red lights side by side mean "stop", two white lights one above the other mean "go ahead". The white lights come on and the bus starts off smoothly and follows its lane. CityPilot recognizes the traffic lights with its sophisticated camera system. In addition, the vehicle communicates via WLAN with the route infrastructure, receiving information on traffic-light status.This means that the bus can "drive" a "green phase" of traffic lights in a targeted manner. Two bridges, an underpass. The bus safely stays in its lane. After leaving the built-up area, it accelerates to the allowed 70 km/h. The maximum speed is programmed; even at this speed the driver does not steer. The bus arrives at the bus stop in automated mode:It stops, the doors open and close, the bus pulls away again. Red lights ahead; the bus independently brakes gently and comes to a standstill safely. While the lights are changing, pedestrians are still crossing the road. The bus waits, lets them cross, and does not drive on until the road is clear. In order to avoid a collision, CityPilot has an automatic braking system that decelerates the vehicles as required.
