Status Quo

In order to expand the range of measures to secure bicycle traffic on narrow roads, the Working Community of Bicycle-friendly Municipalities in Baden-Württemberg (AGFK-BW for its acronym in German) has carried out the pilot project "Safety Lanes" from 2010-2013 and has been assisted by the experts of Kaulen's city planning and traffic planning office. The Ministry of Transport and Infrastructure has supported the project. On several demonstration routes the possibilities of a safe management of the bicycle traffic in narrow streets were examined. As a result, the report shows that safety lanes on both sides of the road with a narrow core traffic lane may well work as a solution. For road widths ≥7.00 m, assured insights are provided for safety lanes arranged on both sides, on the basis of which the current guidelines (ERA 2010) define design requirements and areas of application. The minimum cross-sections of 7 m provided in the ERA are not achieved on many cross-roads. Here, the requirement of the General Administrative Regulation on Road Traffic Regulations (VwV-StVO for its acronym in German) is in principle to secure all traffic participants, as opposed to the standard dimensions of the ERA 2010. In order to obtain reliable information on the use and also the limits of use of double-sided, one-sided and alternating safety lanes, the basic areas of use of these types of guides were examined. The focus was on traffic safety and traffic quality. In order to obtain reliable information about the use and also the application limits of double-sided, one-sided and alternating safety lines, the basic areas of application of these types of guides were examined with regard to various factors: Road width, traffic volumes, conflicts, critical meetings, changeovers, and transition areas- with focus  on traffic safety and traffic quality manipulation.

The city of Offenburg, one of eight participating municipalities, leads its cycle traffic back on the road in accordance with their cycling promotion strategy. Gradually this will

  • implement changes of the Road Traffic Regulations,
  • increase cycling safety,
  • close the gaps in the cycling network by safety lanes for cyclists and
  • put cyclists as road users in visual focus of car vdrivers.

Objective of the project

In addition to the pure factual information that the use of safety lanes for cyclists increases road safety, they should also be perceived as a tool for improving environmentally friendly mobility and further enhance Offenburg's attractiveness as a residential location. In the case of Rammersweierstraße, the commitment of all target groups of the nearby school (parents, pupils and teachers) was of central importance for the success of the project. A communications strategy was developed and one  of the central goals was to actively involve teachers, pupils and parents in the communication. They should assume the role of ambassadors for the project and help shape the communication.

Project implementation

1. School material

In order to put safety lanes for cyclists on  the target group’s agenda, the topic was integrated in school projects and lessons. Worksheets were developed distributed to the teachers and then used in classrooms.

2. On-site inspections for teachers, parents and the transport committee

There was an inspection with the teachers and parents of the schools involved. Here, the advantages of safety lanes for cyclists on the road were explained at crossings and t-junctions, fears could be lightened and suggestions were taken.

3. Communication measures on the street

Advertising materials promoting  the new traffic guidance were distributed to drivers, cyclists and pedestrians at Rammersweierstraße. In addition, the now well-versed students were used as safety lanes ambassadors. The city of Offenburg  organized a "safety box" distribution with active support from the police. For two days between 8 am and 10 am, pupils from the neighboring schools distributed the so-called "Safety Boxes" to drivers. They contained:

  • Flyer about safety lanes
  • Voucher for a security check at bicycle shops
  • Measuring tape "The Safety Lane"
  • Chewing gum "Safety lanes"
  • Clack tape "Striped Safety"
  • Cereal bar "Tailwind".


As a result of the above-mentioned actions, the population is still actively involved in the planning and implementation of measures for cycling promotion and this strategy will be pursued further on.

Why is it an innovative example to follow?

Wie im vorigen Kapitel unter "Ausblick" beschrieben, hat sich die Strategie, "sensible Bevölkerungsgruppen" bereits im Vorfeld und in der Phase der Umsetzung bzw. in der "Eingewöhnungszeit" intensiv einzubinden, bewährt. Besonders hilfreich war im Fall der Zielgruppe "Schulumfeld", dass die Lehrer (insbesondere die Verkehrsbeauftragten der Schulen) aktiv mitarbeiteten und dass die Polizei die Aktionen unterstützte.

Es fand eine indirekte Evaluation statt. Aufgrund der zahlreichen Presseartikel, Leserbriefe, Facebook-Einträge und Stellungnahmen von Bürgerinnen und Bürgern wurde das Thema Radschutzstreifen intensiv in der Bevölkerung diskutiert und die Vor- und Nachteile eines Radschutzstreifens erörtert. Eine breite Bevölkerungsgruppe setzte sich intensiv mit dem relativ neuen Element des Radschutzstreifens auseinander. Es ist zu bemerken, dass die Radschutzstreifen immer besser angenommen werden und sich die anfängliche Skepsis deutlich abgeschwächt hat.
