The TransportTechnical Department of the Cantonal Police is responsible for the traffic arrangements in the cantonal area (excluding cities of Zurich and Winterthur) and provides all road signals/markings. These orders form the basis for tracking the maximum speed signals in the road database LOGO by the TBA. Sections are generated from this data. Every six months the data is exported to the SDE and GIS browsers (including WMS/WFS). The data basis is the spatial data element GIS-ZH No. 54.3 (from spatial data set GIS-ZH No. 54).
