If you intend to do routing on a Network Dataset in ArcGIS for Desktop using OSM data, you should really have a look at ESRI's Open Source and free "ArcGIS Editor for OpenStreetMap". It contains specially designed tools to create a routable Network Dataset from OpenStreetMap data, that deals with the specifics of OSM data in this area. ArcGIS Editor for ...

The ArcGIS network analyst extension needs a properly prepared network dataset (graph) for routing. Ordinary OpenStreetMap data sets are not routable because they are simple linestrings. Take a look at the OSM2NetwordDataset tool by Eva Peters. This tool creates a routable network dataset and takes turn restrictions (from OSM relations), oneway roads and ...

So here are the code and summary of the aforementioned bugs, as requested by @Chris W. Basically they seem to refer to the same issue and to have the same cause, i.e. a problem with the OD cost algorithm. NIM094092 - The OD cost matrix analysis in ArcMap returns different travel time results for one origin if another origin is present. NIM060948 - Time and ...

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

Yes, there are two possible approaches to use. One is to use the OD Cost Matrix tool and simply split up the resulting table. You'd select all records with the same origin point and export them to a new table. There is at least one Split by Attributes custom tool for ArcGIS out there (referenced here but the 10.x link there is currently broken) that can do ...

The short answer is 'yes', scaled cost barriers can be exposed within NetworkAnalyst services in ArcGIS Server, and therefore are accessible to JavaScript applications as well. To leverage this functionality you must include appropriate corresponding attribute values for any barrier Graphics passed in your request. see the discussion of added cost barriers ...

One possibility would be to use a turns feature class or table to model an increased time impedance for all turns. The idea would be to use a high value for turns (such as 15-20) seconds, and a low impedance for straights (0-5). Then, as routes are created, every time a turn is the "fastest route", the additional impedance time will likely influence the ...

If your real problem is to measure the distance between X and Y, you can use OD Cost matrix. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00470000004r000000 Edit: It doesn't generate routes but adds distances calculated from routes to the output table.

Just off the cuff.. you might try first extracting the endpoints of your line features, then extract the DEM elevation values for line endpoints and the manholes. 1) Feature Vertices To Points (Data Management): Turn your pipe line features into endpoints. Note the graphic describing your different point_location options. 2) Extract Values to Points ...

You are making the classic mistake that a lot of people do. If you read the help file of the Append tool it takes a LIST of datasets. Currently your model is appending on ever iteration which is very inefficient. You can improve model performance by sending the output of the Select Data tool (Routes) to an in_memory workspace then feed that tool into a ...
