Test in 30 cities and municipalities

Model project for advisory cycle lanes for bicycle traffic in Baden-Württemberg

© Jörg Thiemann-Linden

The Working Group of Bicycle- and Pedestrian-Friendly Communities in Baden-Württemberg e. V. (AGFK-BW) is investigating different variants of new types of cycle lanes in two model projects on numerous pilot routes throughout the state. They are investigating how advisory cycle lanes should be designed so that safe traffic routing is possible for cyclists. The project is the largest model project of its kind in Germany to date. It is investigating how cycle lanes should be designed so that safe traffic routing is possible for cyclists. The model projects are funded by the Baden-Württemberg Ministry of Transport. The model projects will run for three years. They started in 2019 and will be visible on roads in Baden-Württemberg from spring 2020, when the line markings will gradually be installed in the municipalities. Around 30 municipalities are participating in the model project.

Where it is not possible to build a dedicated cycle track, cycle lanes can be a comparatively simple and inexpensive way to make cycling safer and create continuous cycling networks. So far, however, it has not been sufficiently investigated under which conditions such lanes can also make cycling safer and more attractive outside built-up areas and on narrow roads within built-up areas and provide safe traffic guidance for cyclists. So far, these forms of cycle lanes have only been permitted with exceptional approval.

The focus of the investigations in urban areas is on cycle lanes on both sides of roads with a narrow core carriageway. Up to now, only narrow cycle lanes have generally been marked on such narrow roads, and motor vehicles have retained their space. The model project for cycle lanes is now investigating how traffic behavior changes when these lanes are marked wider at the expense of motor vehicle lane width. The use of one-sided cycle lanes on sections with inclines is also being investigated. Here, the speed difference between cyclists and motor vehicles is particularly large. Cyclists riding uphill will thus enjoy special protection with the new cycle lane.

Cycle lanes are not yet permitted outside built-up areas. Here, the areas of application for marking cycle lanes on one or both sides are being investigated and evaluated depending on the traffic load and structure of the road, the topographical conditions and the given road widths.

The model projects are to be evaluated by 2021. The measures will be implemented by different authorities. Scientific support is provided by the urban and traffic planning office brenner Bernard and the planning office VIA.
