Real-time traffic management sounds futuristic, but it's operational right now in cities across Germany and Switzerland. Here's the technical setup: LTE-M connected sensors and cameras monitor vehicle flow at intersections. That data feeds into a traffic management platform that adjusts signal timing dynamically based on current conditions, not fixed schedules. Why LTE-M specifically? It supports mobility, handles frequent data updates, and provides the 50-100 millisecond latency these applications need. WiFi and Bluetooth don't have the range. Older cellular technologies don't have the power efficiency. Cities in the DACH region are taking this further by integrating traffic data with air quality monitoring. Herrenberg measures traffic volume alongside noise levels. When patterns indicate increased emissions or noise pollution, they implement targeted interventions: adjusting signal timing to reduce idling, routing traffic away from residential areas during peak times. The result is measurable: smoother traffic flow, lower emissions, improved air quality. It's infrastructure that actually adapts to how people use the city. Watch the video to see how the technology works and why these specific technical choices matter for urban deployments.
