Is there a way to generate values for "wait time", "walk time" and "transit time" separately?

Thanks for replying, Melinda. My analysis needs to separate the walking time and the transit time on train/bus. And due to the size of my data, I need to use Python command to do the Network Analysis instead of clicking on buttons on the menu. When I tested the menu options (so that I can create my arcPy commend accordingly), I found that the output route file only provides values for "Total_PublicTransitTime" if I choose "Mode: Public trasnit time " in the "Travel Settings" banner in the Network Analysis. The output column "Total_walktime" will be "null". However, if I clicked on the blue sum sign and check both "PublicTransitTime" and "WalkTime", the output file will give me the walk time I need. Is there anyway to include this option into the python command?

Hey, I am using arcpy.na.solve to find the best transit route using network converted from GTFS data. I need two cost attributes to be combined: public transit time and walk time. How should I set up the travel mode? Here is what I use for public transit only (which works fine): travel_mode = "Public transit time" arcpy.na.MakeRouteAnalysisLayer('TransitNetwork_ND','Route',travel_mode) Thanks Jane

I have built a network from shapefile using "minutes" as the cost field. The "minutes" field needs to be updated several times and each time a new fastest route needs to be generated between a pair of O/D. I tried to use python code (arcpy.buildnetwork_na) in the embedded window in ArcGIS to do this automatically. However, it doesn't work, even though I removed the network AND the orginial shapefile from my ArcGIS (due to the "exclusive schema lock" issue). Anyone knows what's going on here? Thanks

I have a similar situation. I created a network from my shapefile. The "Minutes" field needs to be updated and each time it updates I need find the shortest path. That means, I need to build it each time the "Minutes" changed. It won't allow me to re-build, saying "Runtime error <class 'arcgisscripting.ExecuteError'>: ERROR 030033: Parameter does not contain a network dataset data element." I used "arcpy.BuildNetwork_na". This network is not a SDC file, right? Since I can manually build it from ArcCatalog. Any suggestions?
