Ranking of Switzerland's most congested cities in 2024. Zurich, Geneva, Basel, Bern and Lausanne: TomTom data on hours lost, peak times and year-on-year trends.
Switzerland is often held up as a model of efficiency — but urban traffic tells a different story. According to the TomTom Traffic Index 2024, Swiss commuters lose tens, sometimes hundreds, of hours per year sitting in queues.
This analysis compares the 5 major Swiss cities using real data: congestion level, year-on-year change, time lost and critical peak hours.
| City | Congestion | Hours lost / year | Change | Global rank |
| Zurich | 27% | 107 hrs | -2% ✅ | #87 |
| Geneva | 26% | 92 hrs | +1% ⚠️ | #101 |
| Lausanne | 21% | 74 hrs | +2% ⚠️ | #162 |
| Basel | 22% | 73 hrs | -1% ✅ | #148 |
| Bern | 20% | 68 hrs | 0% ➡️ | #178 |

With a 27% congestion rate and 107 hours lost per year, Zurich is Switzerland's most congested city. Peak times concentrate around commuting hours: 07:30–09:00 and 17:00–18:30, with the A1/A3 motorway as the most critical stretch. Congestion dropped 2% year-on-year thanks to expanded public transport.

Geneva has a 26% congestion rate — second in Switzerland, but with a structurally different challenge: the French border generates tens of thousands of daily commuter movements that saturate the road network. Route de Chêne, the airport interchange and the city centre are the critical hotspots. In 2024 the situation worsened by 1%.
Basel records 22% congestion — a respectable figure for a city at the junction of three countries. International transit traffic burdens the network, but an efficient tram system absorbs much of the pressure. Congestion improved by 1% in 2024.
Lausanne is 2024's negative surprise: 21% congestion and +2% year-on-year. Population growth in Vaud canton is outpacing road capacity, and the hilly topography makes widening roads difficult. The Blécherette interchange and the A1 towards Geneva are the main hotspots.
Bern is the least congested major Swiss city: 20% congestion and a stable trend. The Felsenau viaduct and Kirchenfeldbrücke remain the main bottlenecks. Institutional traffic from parliament adds pressure during legislative sessions.
Anyone driving the A2 towards the Gotthard Tunnel typically starts from one of these cities. Urban morning congestion in Zurich, Geneva or Basel adds directly to Gotthard delays: leaving after urban peak hours can make the difference between a smooth journey and hours of queuing.
Recommended strategy:
The TomTom Traffic Index measures the percentage of extra time needed under real conditions versus free-flow. A value of 27% means a 30-minute free-flow trip takes on average 38 minutes. Data is calculated from billions of GPS points collected from vehicles, smartphones and connected devices throughout the calendar year.
107 hours lost per year in Zurich — and rising trends in Lausanne and Geneva. Anyone driving to the Gotthard should factor in the congestion of their departure city when planning the trip.
