Zurich model
Appearance
Zürich model is a name used to refer to the approach which permitted the public transportation system of the city of Zurich in Switzerland to achieve and maintain a high market share. Many other cities have emulated elements of it, especially when new tram systems were being introduced.
History
In the 1960s, Zürich was planning to move many of the tram lines in its central area into tunnels. This project was rejected in a referendum. In the 1970s, a project to create an underground railway was similarly rejected.
Despite the failures of these attempts to provide Zürich with a different kind of transportation system, public transportation in Zürich maintains a high modal split. This was achieved through the optimization of the existing system.
Elements of the model
- A dense network providing many direct connections and short headways.
- High priorities at intersections.
- Low impact of road congestion on operations.
