Why cycling is twice as dangerous in Switzerland as in the Netherlands

Swiss cyclists face twice the accident rate recorded in the Netherlands when the figures are measured against kilometres travelled. A study published in the specialist journal Journal of Safety Research examined more than 86,000 police recorded cycling accidents between 2019 and 2022. It found an average of 0.19 accidents per 100,000 kilometres in Switzerland, compared with 0.09 in the Netherlands.

The comparison measures exposure to risk rather than simply counting crashes. That matters in a country where cycling levels, urban layouts and travel patterns differ sharply from the Netherlands. The researchers, from the University of Twente and ETH Zurich, used police records to identify where and how cycling collisions occur.

Their findings point to specific weaknesses in Swiss street design. Public transport stops, tram tracks and junctions repeatedly place cyclists in conflict with buses, pedestrians, cars and rails. The report arrives as cycling accidents in Switzerland have increased by 50% over ten years, according to a related Swissinfo.ch report published in March 2025.

The figures do not suggest that every Swiss cycling journey is dangerous. They show that the places where cyclists must negotiate several forms of traffic deserve urgent attention from city planners and transport authorities.

Public transport stops are a central danger point because Swiss cycle lanes often run directly through the space used by passengers and buses. A cyclist passing a stop may encounter people stepping into the lane, a bus pulling in or doors opening beside the route. The same design can force cyclists towards moving traffic when they try to avoid the obstruction.

Lead author Georgios Kapousizis said Dutch cities commonly place cycle paths behind public transport stops. That layout separates cyclists from passengers boarding buses and trams, while also keeping bicycles away from vehicles stopping at the kerb. It reduces the number of decisions that road users must make in the same few metres.

The difference is visible in the street geometry. A protected cycle path behind a stop creates a predictable crossing point for pedestrians. A cycle lane between a bus and the pavement creates a moving corridor beside a vehicle that may stop without warning.

Kapousizis argues that Swiss cities can adopt the Dutch approach without developing an entirely new transport model. The proposal has direct relevance for urban areas such as Zurich, Basel, Bern and Geneva, where cycling routes increasingly share narrow corridors with extensive public transport networks.

Junctions and tram tracks expose a second layer of risk, bringing cyclists into close contact with turning vehicles and difficult road surfaces. The study found that accident risk at junctions was significantly higher in Switzerland than in the Netherlands. Intersections require cyclists to read signals, turning movements and lane changes at the same time, often without physical protection.

Tram rails create a separate hazard. A bicycle wheel can catch in a rail, particularly when the track crosses the cyclist’s path at a shallow angle or when wet conditions reduce control. The danger increases when cyclists must move across tracks to avoid parked cars, traffic lanes or a tram stop.

The researchers recommend protected cycle lanes and dedicated cycle traffic lights at junctions. Those measures give cyclists a defined route and reduce uncertainty about who has priority. Around tram lines, they call for structural solutions that prevent wheels from entering the rails.

Swiss cities face practical limits. Historic centres often leave little space for widening roads or separating every mode of transport. That makes design choices more important. Clear crossings, safer rail alignments and protected waiting areas can reduce conflicts without removing public transport from central streets.
