Network analysis issue

Question

Hello everybody !

I am encoutering an issue using Network analysis extension on Arcmap 10.5.

What I would do is by the use of a route analysis, generate a route for pedestrian on sidewalks of a city.

I followed a tutorial which has permitted me to generate a route for the visit of every subway station of Paris (just an example!)

So my issue is the following : 
- In the tutorial I have data for the streets represented by lines that are all linked.
- In my dataset, sidewalks are represented by polylines that are NOT linked.

I can't manage to do this analysis. Please if someone has an idea on the subject, let me know.

The Network Analyst is what is used for movement studies using linear networks.  I don't think even the Spatial Analyst with its Cost Path analysis would help.

Thanks for all of your replies. I'll try to find an other dataset representing streets, or at least informations about missing crossings. Do you think that my issue could be solved using an other extension for example?

From your screen shots, it looks like you do not have a street network. You have polygon blocks that do not connect to another polygon block. As in your not working screenshot, there is no link between stop 3 to stop 4. The streets are missing. You will have to either convert these to centerlines and set up all the attributes like street names, travel costs and restrictions such as pedestrian crosswalks, etc., or get that street data from a vendor. It is not going to be easy to convert these polygons into streets.
