“trafficpilot” app: No more red lights

With a “Green Wave App” for drivers, the city wants to reduce noise and pollutants in road traffic.

The city announced that the “trafficpilot” app, which is now available free of charge for Android and iOS smartphone devices, shows the speed that you should keep to in order not to have to stop at a red light at the next traffic light.

According to the head of the mobility department, Stefan Majer (Die Grünen), this is made possible by the information from 441 traffic lights that arrive at the Frankfurt traffic control center every second.

The app, the development of which, according to the city, cost around 256,000 euros and was half funded by federal funds, uses the coordination of switching times at traffic lights and can also be used by cyclists.

Depending on the position and direction of travel, the current red-green forecast for the next traffic light is displayed.

Colors symbolize the reliability of the forecast and how you should adapt your driving behavior in order to get through the next intersection when the light turns green.

Save fuel, reduce emissions

If you drive too fast or too slowly, you leave the “green wave” and drive in the red zone.

The display of the current speed also helps.

Drivers save fuel and reduce emissions, and cyclists can cross the next intersection with ease.

If you still have to stop, you are shown, if available, in how many seconds the traffic light will switch back to green.

From the point of view of the head of the road traffic office, Petra Lau, "trafficpilot" is a further step in the digitization of traffic systems.

"We are now able to pass on our data directly and make connected driving usable for individuals," she said.

The app promises fewer stops at intersections for motorists and cyclists, making an important contribution to increasing road safety and traffic efficiency.

The "trafficpilot" has been extensively tested, already has a promising forecast accuracy and is continuously being improved.

Because looking too closely at the cell phone display could, in the worst case, lead to more accidents, there are clear warnings before the app is activated.

"The display may only be looked at in safe traffic situations," it says, for example.
