You are getting that result because you chose PedestrianTime for your Impedance. The solver only considered the streets because of that. The PedestrianTime network attribute represents the time it takes a pedestrian to travel on the network. If you wanted the best route, you should set the Impedance to TravelTime. This is explained in Exercise 3: ...

You will most likely need to create transfer edges. I have found the ESRI help on this topic to be quite informative, as well as the 2nd exercise in the Network Analyst tutorial.

Based on what you said, let's consider that you want to minimize the walking distance from point A to point B. Stated like this, you need to solve your model based on the minimum walking distance, which means that the "cost" of the metro is "zero". This will force network analyst to use metro more often, though you will avoid using metro in trivial cases ...

I describe a raster-based method in the US patent Methods and Systems for Optimizing Network Travel Costs, US 8332247 B1 (published December 2012 with priority back to 1997). The idea is that a raster decomposition of the ambient space furnishes a dense mesh to which your network nodes can automatically be "snapped". Costs ("impedances") attached to the ...

This could be part of the problem The streets are not split at intersections. If they aren't split at intersections then If they do not share any coincident endpoints or vertices, no connectivity policy will create a junction at the point of intersection. Street data for network datasets must be cleaned first so that either vertices or ...

If I understand you correctly, you are basically wanting a 2-mode network dataset with the bus stops as transfer points, correct? If this is the case you have a couple of options. First, the bus stops need to be in some way connected to the network at a vertex (on both layers). If the bus route overlaps the streets then a transfer edge is unnecessary and ...
