We'll explore using deep learning to improve urban traffic signaling. Bicycles (both self-powered and pedelecs) are the future of urban transport alongside (self-driving) electric cars, buses, and rail services. Green waves make cycling more efficient, attractive, and safer. Instead of fixed ""green wave"" timings or priorities, a work in progress system is presented that learns to increase the flow of bicycle traffic while minimizing the impact on other traffic actors -- and in many use cases also results in improvements in general traffic times. Using low power efficient SoCs -- Tegra X1 -- the ""smarts"" are integrated in traffic lights and provide V2I interfaces -- also to mobile phones of cyclists -- about signal changes and warn of pedestrians or cyclists. Dispensing with inductive loop, magnetometer, or radar-based sensors buried in the pavement makes the system inexpensive. We'll present initial results from pilot testing in a German city.
