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.

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: ...

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 ...

You would need to have only meta nodes representing intermodal transfer points cause modeling this network with access at every node-intersection would be meaninless for routing and analysis. You could use oding so that different feature classes could only be accessed by a certain flag at inter-modal points. Create meta data object oriented models of ...

I'd say very small links around rail/road intersection nodes will do

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 ...

First you should snap points to lines .You can use GME (Snap Points to Feature ). If you want to use bus stations for routing you should create multimodal network.Follow the Multimodal network excercise. You should create stations,entrances, Bus lines , use ovverride for entrances then build your network dataset.

My first suggestion would be to investigate the geometries involved. Note that snapping is not enough - the layers must be coincident, meaning in order for a network junction to occur there must be a vertex at the same point in all related layers. You can't just snap the stop points anywhere along a route segment/edge (nor for that matter will a junction ...

Serving map tiles Tilestream is nice but if you want to have live maps (showing new OSM data as they happen) you need Apache and mod_tile (I think this is also used in main OSM site). You download OSM extract from geofabrik or anywhere else set up postgresql server. And updating mechanism. And them every time tile is requested it is checked if data was ...

ESRI Street Map Premium for ArcGIS is network ready, and they have datasets for Europe too.

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 ...

According to this post on timetable-based routing on the ArcGIS forums, this is not possible as of yet in Network Analyst.
