**4. Discussion**

Through slow mobility, it is possible to guarantee social distances and avoid tra ffic congestions without increasing the number of cars. From this point of view, it is necessary to study all possible zero-impact solutions starting from the analysis of itineraries and comparing the judgments before and after the pandemic. Mobility on foot within urban centers is being increasingly used by students and workers who want to move from home to their destination at distances of less than a kilometer. The results obtained in this research are in line with the results obtained in another recent research.

The distribution in the choice of itineraries was quite uniform with a slight prevalence in the selection of Itinerary 4 characterized by the presence of a well-lit and clean subway.

In accordance with [80], there was a decrease in the use of the subway with age. The perception of the pedestrian safety level was not entirely negative due to the fact that the infrastructure is constantly maintained, and local policies tend to promote strategies in favor of walking.

The AHP analysis has revealed the perceptions of pedestrians concerning the 4 routes in the same environmental conditions. However, this assessment is carried out on a small sample, which highlights the need to know not only the geometrical-functional characteristics of an infrastructure, but also the judgement of the people who habitually use the roads. This fact is of fundamental importance if a participatory planning of the city is to be implemented [81,82].

The overall satisfaction regarding the infrastructure was average, a fact that indicates that this aspect could be analyzed further. The greatly positive assessment of walkability of the infrastructure by the participants indicates that the lower satisfaction regarding the level of service has some complex motives.
