Table 5: Criteria and data sources for the case study of the city of Köthen. Table 5 shows, on the one hand, that it was not possible on the basis of the available data to determine the traffic diversity, the number of accidents, data on the number of days with fog and dust, or information on a low sun. From the authors' point of view, it is possible that the traffic diversity and the number of accidents could be determined in other localities on the basis of local surveys. For this reason, only the last three criteria were excluded from further consideration. Furthermore, although it was generally possible to determine whether a lane was dirty using OpenStreetMap, Google Maps and Apple Maps, these data were not updated daily. For this reason, this criterion was also excluded. The criteria number of satellites, rain, temperature, wind, and snow could only be determined for the city as a whole and not for individual streets. Therefore, the authors recommend dividing the route evaluation and first carrying out a higher-level evaluation of the city or district. This should be conducted on the basis of the following criteria, with the weighting based on the evaluation from the expert survey (Table 6):
