To encourage walking and cycling, Frankfurt is redesigning several side streets with a variety of provisional measures, including cycling priority, modal filters, multifunctional lanes, green elements, etc. If these experimental measures are effective and accepted, they will be made permanent. The effects are therefore evaluated using quantitative and qualitative research methods. The paper centres on the analyses of Oeder Weg, a bustling business and shopping street. So far, the surveys have revealed notable differences between various groups, such as the assessment of perceived traffic safety and the approval of individual measures. Many residents and almost all cyclists are in favour of the redesigned road space because they feel safer and the street is more attractive to use. Frequent car users complain of poorer accessibility and lack of parking facilities. Also, local businesses react heterogeneously. While restaurant owners are pleased about more outdoor space and an increased quality of stay, many retailers complain about the worsened conditions for customers who come by car. A large proportion of the customers surveyed does not share this assessment though, as many come by bicycle or public transport. The traffic observations have shown that objective traffic safety has improved at conflict points in the road space, e.g. through new markings in the dooring zone or curb extensions in intersection areas. Overall, the modal shares have shifted considerably. Motorised individual transport has decreased significantly in Oeder Weg, but has increased in some adjacent streets, which has led to an adjustment of the traffic guidance measures.
