Service areas are kept in memorry and that can cause you to run of memory when doing so many at one time. You can change this behavior by "chunking", that is, doing a few at a time and writing them out. To enable this you need to add a registry key. Details on this are in the following article: http://support.esri.com/en/knowledgebase/techarticles/detail/38426 Jay Sandhu

Instead of using the Copy Traversed Source Features tool, use the Solve tool to solve the layer again. Does it run successfully? If you get the same error message then you have probably moved the network dataset and/or the route analysis layer to another location and may need to "repair" it. The Copy Traversed Source Features tool needs to re-solve a saved route layer to be able to generate the traversed edges. Jay Sandhu

One other thing you can make sure to check is in the ArcMap top menu, click on Geoprocessing and select Geoprocessing options and make sure that the "Add results of geoprocessing operations to the display" is also checked on. Jay Sandhu

Make the results of the Solve be a model parameter. Read more here on how to display the results of a model. http://resources.arcgis.com/en/help/main/10.1/#/Displaying_model_data/002w0000003q000000/ Jay Sandhu

Amber, According to the article: The Ant algorithm, inspired by the nature, is based on the capability of ants to locate the shortest path between their nest and the food source while searching for food. The Ant algorithm is an adaptive construction heuristic combined with a local search measure. This is one way to solve location problems using a heuristic. This particular heuristic is implemented by the authors in their own environment. It is not available directly in ArcGIS. However, the network analyst extnension provides similar capabilities in the Location-Allocation solver with the option to "maximize coverage" that is targeted towards fire station location. Perhap you can use that for your needs. The details are here: http://resources.arcgis.com/en/help/main/10.1/#/Location_allocation_analysis/004700000050000000/ and a tutorial: http://resources.arcgis.com/en/help/main/10.1/#/Exercise_9_Choosing_optimal_store_locations_using_location_allocation/004700000067000000/ Regards, Jay Sandhu

Andy, This is straightforward to accomplish using the Network Analyst extension. See my post in the following thread on the details on how to do this: http://forums.arcgis.com/threads/73964-Connect-multiple-(longitude-latitude)-points-with-other-ones Use the streetmap network that comes with ArcGIS and Business Analyst. It is ready for routing and you do not need to do anything more to use except to add it to ArcMap table of contents. Jay Sandhu

ArcMap takes care of projecting data to the current map projection. So that should not be an issue. If the points are very far away then most likely when you create the feature class from the excel table you mapped the Latitude as X and Longitude as Y. You need to reverse that and recreate the point feature class mapping Latitude as Y and Longitude as X. Jay Sandhu

Make sure to have some ID field in your excel sheet that you can use later to pair up the pick up and drop off points. Then add the excel spread sheet to ArcMap (from catalog window). Then from the File menu choose Add Data and then choose Add XY data. On the form for AddXY data, choose the excel table and then map the first set of Longitude and Latitude to the X and Y fields and click OK. This will create a new point layer in ArcMap. Repeate the above process with the second set of Longitude and Latitude and click OK. Now you have two feature classes with the pick up and drop of points. To create "routes" between these pairs, use the Route solver. DO NOT USE the OD Cost Matrix Solver for this as that will only create distances (not route shapes) between ALL pairs. To use the Route solver, you need a network dataset of streets. If you do not have one, then use the free streetmap network that comes with ArcGIS. Once you add that to ArcMap, use the NA toolbar to create the route layer. Then make the NA window active and right click on the Stops and choose Load Locations. Now load the first point layer MAKING SURE that you map the RouteName property to the common ID. Repeate the process with the second point layer using routename and same ID mapping. This will create multiple route pairs in the same route layer. Now Solve and you will get routes from each pickup to each drop off point pairs. Jay Sandhu

Streetmap data comes with the network dataset already built and ready to use and has the travel time attribute built. Are you not able to use that network dataset? You should not need to add a travel time field to your data. Jay Sandhu

Does the feature class that you are using to create the network dataset have 3D coordinates? That is, does the shape field say it is polyline or "Polyline Z"? If it is not Polyline Z then it does not have Z coordinate (in addition to the X and Y coordinates) to build a 3D network. You will need to convert the data into polyline Z and add the right Z coordinates to make a 3D network as in the tutorial I mentioned. Jay Sandhu

You should start by going through the tutorial on 3D networks which explains how to set up the network for the different floors and then route on it. You can access the tutorial information here: http://resources.arcgis.com/en/help/main/10.1/index.html#//00470000005q000000 Jay Sandhu

You can create a feature dataset with the right equidistant projection and then use the GP tool Create Fishnet to create a new grid feature class with the right properties. If you already have a feature class that has 20 km edges, it will only matter what projection it is in if you are going to project it to something else later. And yes, anytime you project the data, the actual length of lines can change. However if your goal is to simply have a grid with exactly 20 km as a length value, you could either add some length field to the feature class and calc it to 20 and use that in the length attribute of the network dataset OR simply add an attribute length and set it's evaluator to a constant value of 20!

The resulting network looks just fine at first (after rebuilding) but the oneway roads have lost their directions and are often going into the wrong direction. Just to re-emphasize what Doug said in the previous post, the dissolve tool can flip the digitized direction of the edges BUT it will also the flip the attribute of the ONEWAY field to match the flip. So you should get the same routes on the resulting network as you did before. Jay Sandhu

You should geocode your excel sheet twice and get two sets of point feature classes output from this process. Now you can load them in to the same route layer making sure to map the common ID as the RouteName and you will get the route sovler set up to solve paths between pairs of stops. Jay Sandhu

The ArcGIS Server and ArcMap call the same underlying solver. So there should be no difference in how the actual solve happens. The difference is in what settings are on or off between the two different ways to call the underlying solver. Perhaps there is some different restrictions set, or in ArcMap hierarchy is OFF but server has it set to ON, or the points are being located on a different edge or with different curb side properties. So I suggest changing some properties in ArcMAP and seeing if you get the same route as server. If you cannot find any differences, then I suggest you can turn on logging in the server and capture the calls being sent for the route solver and post them here and also post a screen shot of the proprerties of the route layer (analysis settings and/or attribute parameters) from ArcMap and also the route/directions that you get from server.
