Copenhagen's Cycle Super Highways (Supercykelstier) is an expanding network of premium cycling routes connecting the Danish capital with surrounding municipalities in the Greater Copenhagen region, designed to make long-distance bicycle commuting fast, safe, and comfortable. The network features smart traffic signals that detect approaching cyclists and turn green to create a continuous 'green wave', IoT-based traffic counting infrastructure that monitors cycling volumes and patterns, and weather-responsive maintenance systems that prioritise snow clearance and surface treatment on Cycle Super Highway routes.
The network currently comprises multiple completed routes with additional routes under construction and in planning. Each route is designed to a high standard, with wide, smooth surfaces, gentle gradients, clear wayfinding signage, and separation from motor vehicle traffic. Rest stations with air pumps, repair tools, and real-time route information displays are positioned at regular intervals, reinforcing the message that cycling is a first-class mode of transport deserving of infrastructure investment comparable to that provided for cars.
The smart traffic signal system is a particularly notable feature. Sensors embedded in the cycle path detect cyclists approaching an intersection and communicate with the traffic signal controller to extend or trigger a green phase, allowing riders to maintain a steady pace without frequent stops. This green wave technology significantly reduces journey times and makes cycling a more attractive alternative to driving for commuters travelling distances of 10 to 30 kilometres.
Data from the network's IoT counting stations feeds into Copenhagen's city data platform, enabling transport planners to understand cycling demand patterns, evaluate the impact of new routes, and make evidence-based decisions about future network expansion. The Cycle Super Highways support Copenhagen's goal of achieving a 50 per cent cycling commute share and are widely regarded as a global benchmark for smart cycling infrastructure.
