trafficpilot bietet eine Turn-by-Turn-Navigation mit integriertem Grüne-Welle-Assistenten. Die Navigation basiert auf den umfassenden OpenStreetMap-Karten und unterstützt die schrittweise Navigation zum gewünschten Ziel im Auto- oder Rad-Modus, mit 3D-Karte und Navigationsanweisungen im Bild und als Sprachausgabe. Auf dem Handy stehen neben der 3D-Karte auch eine 2D-Übersichtskarte und ein Prognose-Modus zur Verfügung, der ausschließlich die Grüne-Welle-Assistenz für die nächste Ampel anzeigt. Die Grüne-Welle-Assistenz erkennt in unterstützen Gebieten anhand GPS-Ortung und integrierter Kartendaten, auf welche Ampel sich der Fahrer zubewegt und gibt an, ob die Ampel bei der aktuellen Geschwindigkeit bei Grün oder Rot erreicht wird. Ein Rot-Grün-Teppich visualisiert diese Information: Ein grüner Bereich bedeutet freie Fahrt, ein roter signalisiert einen wahrscheinlichen Stopp. Anhand der Farbeinteilung auf dem Handybildschirm kann man einschätzen, ob man seine Fahrgeschwindigkeit möglicherweise anpassen sollte, um die Ampel bei Grün zu passieren. Hilfreich ist auch die „Time-To-Green“-Anzeige: Steht man an einer roten Ampel, zeigt die App die verbleibende Zeit bis zur nächsten Grünphase an. Eine Sprachausgabe informiert einige Sekunden vor dem Umschalten – ein Feature, das nicht nur den Fahrkomfort erhöht, sondern auch die Aufmerksamkeit auf die Straße lenkt. Die CarPlay-Integration ermöglicht die Anzeige der Navigation und der Grüne-Welle-Assistenz (GLOSA) im Fahrzeug-Display.

With the Signal2X traffic light phase assistant from Yunex Traffic, cyclists and car drivers can catch their next traffic light on green! Our app helps you to adjust your speed in advance so that you can cross the next traffic light without stopping. Our traffic light assistant ensures a green wave in your city! And if a red light is unavoidable, a countdown will show you how long the light will remain red. With our app, you ensure a positive, traffic-harmonizing and thus pollutant-reducing effect! These functions are made possible at traffic lights that are equipped with an intelligent switching forecast service. This is currently the case in the city of Darmstadt, for example. As soon as you approach a corresponding traffic light, our app shows you a visualization of the lanes with the corresponding display of the current traffic light circuit, as well as the speed recommendation with which you can reach the traffic light when it turns green. If you are outside the area of influence of the traffic light, your position will be shown on a map. About the City of Science Darmstadt: Honored with the title "City of Science" since 1997, the state of Hesse thus recognizes the national and international importance of the city of Darmstadt in the fields of science and research. Thanks to these unique circumstances, Darmstadt is the ideal place to test and further develop our Signal2X app. Because we are not only relying on the great interest in new technology, but also on the fact that we can optimize our app for the benefit of the end user through the feedback of all users. We are therefore very interested in your feedback, so don't be shy! In addition, the entire road network of Darmstadt will be equipped with our technology over time, so you will soon be able to use Signal2X throughout the city. System requirements: iOS version 17 Apple CarPlay: The Signal2X app also includes an extension for Apple CarPlay. To do this, connect your smartphone to your vehicle and open the app in Apple CarPlay. Have fun on your journey!
