Figure 39. Overview of Vienna STEP UMP's Phase 4 analyses

mentioned by the plan was the Vienna Play Street model sections of streets closed to traffic and opened up to children in the afternoon which has been implemented in many districts and is planned to expand, especially in consolidated areas where there is hardly any open spaces.

However, most of the results shared have been related to successes, not failures, which are also part of the evolution process. Hence, Vienna should also contemplate its failures in updating the following plans since not everything ended up exactly as planned, and many lessons could be learned from those. Therefore, Figure 39 displays the summary of the STEP UMP analyses from SUMP Cycle Phase 4, in which only one activity has been covered, four others have been partially covered, and two others have remained unclear.

Thus, it is well known that Vienna has been achieving many outstanding results. However, as failures, consequently addressing new challenges and possible solutions in the following planning process to achieve even better future results.

4.1.5. Principles of SUMP

After scrutinizing STEP UMP throughout the SUMP Cycle, this research has enhanced the analyses by employing the online SUMP Self-Assessment Tool to evaluate to what extent the Viennese strategic mobility document is fulfilling the SUMP Principles. The overview
