From your screenshot, I presume your question refers to Service Area analysis layers and not the Generate Service Areas ready-to-use tool, which is a specific thing.  Your screenshot appears to show part of the Travel Mode tab in the Service Area layer properties dialog. A Travel Mode is a collection of settings that model a particular mode of travel or vehicle type. The travel mode includes things like the cost attribute to be used for the analysis (the thing being optimized) and restrictions, u-turn settings, etc. The Cost Attribute (also called Impedance Attribute) is the thing being optimized in your analysis, such as travel time or distance.  It appears that your network dataset has a cost attribute called TravelTime. The Service Area will calculate the TravelTime for each road segment starting from the facility and travel outward until it hits the limit specified. Attribute Parameters are properties of cost attributes that control or modify their behavior.  For example, if you had a cost attribute that modeled walk time, that attribute might have a parameter for walk speed.  The cost would be calculated by dividing the length of the road by the walk speed parameter value.  You could change the parameter value at solve time to increase or decrease the walk speed, and that would change the results of the analysis. Here is some documentation about parameters: Use parameters with network attributes—ArcGIS Pro | Documentation  The Service Area layer's Travel Mode properties let you examine and update the various travel mode properties.  If you click on any of the rows in that Cost Parameters table, it should expand and show you a detailed view of the parameters that apply to that cost attribute and their values for the particular travel mode your layer is using. From your screenshot, it appears that your TravelTime cost attribute has some parameter whose value is Null.  If you click the row in the table, it should expand and show you what the parameter is called.  I can't really guess from the information you've provided, and it's not clear whether you would need to enter a value there to produce good results.  Hopefully whoever created the network dataset configured the cost attribute and associated parameters correctly such that Null is a valid value. ...

Hi Martin.  Sorry it took a while, but we have added a new tool to the BetterBusBuffers toolbox, Count Trips at Stops by Route and Direction.  It counts the number of transit trips that visit the stops in your transit system during a time window. In contrast to Count Trips at Stops, this tool does not combine trips from different routes or directions of travel. Instead, if a stop is used by multiple routes and/or directions, the stop will be duplicated in the output.   Download the newest version of the toolbox here: https://arcg.is/0yr9fr Does this serve your needs? ...

Unfortunately, this is not really possible.  The Route solver only returns one result, the optimal path between the points. The only way to get alternate routes is to use barriers to block certain streets or transit lines and then solve again. ... View more

This is correct and intentional.  Older versions of Pro used sequential integers, but for a variety of reasons to avoid conflicts, we updated it to use a random string.  You should not rely on the feature dataset and feature class names for anything in your analysis or code you're writing.  That was never the intended use.  If you're having trouble with your code, please add more details to your question, and I can help you out. ...

You say that you are using ArcGIS Pro, but you didn't say what kind of network you're using to solve your analysis.  The answer may depend on that. If you're using the ArcGIS Online services, or a non-editable network dataset, you will need to determine whether the network already includes both ferry lines.  If so, you can probably solve the problem by using barriers to block whichever lines are not running on the day when you are solving the problem, which will force the use of the other line. If the lines are not included, you will need to build or edit your own network dataset locally to include the ferry lines.  Then you could use the same barrier approach described above. You can use the true ferry schedules if you can obtain a GTFS dataset that includes the schedules for the ferry. You can set up a network dataset with public transit schedules using the information here: Network analysis using public transit data—ArcGIS Pro | Documentation  ... View more

You cannot.  If you want to re-add the layer in the future, first use the Save To Layer File tool to save it as a .lyrx file, or save it as a layer package.  If you have not done either of those things, there is no way to retrieve the layer from its feature dataset. It's gone. ... View more

That's correct, there is no C# option, just the python. ... View more

I have just about reached the limit of what I can do to help you here on GeoNet.  It sounds like you have a lot of questions about both the basic functionality of the ArcGIS platform as well as some specific questions about how you can accomplish your specific workflows.  I think it would be best for you to call Esri Support or the support through the distributor for your country.  They can answer all of your questions and help you figure out your workflow. ...

Can you clarify what you mean by "network model tool"? ... View more

I can see in the video above that you are not using trim and that you have selected Detailed polygons.  The Detailed polygons in ArcMap will never use the new Service Area algorithm.  If you want to use detailed polygons and see the nice new polygons, you need to use ArcGIS Pro. If you want to get rid of spikes using your existing Service Area layer in ArcMap, I suggest you set a polygon trim of something like 50-100 meters. ... View more

Hmm, that still does not look like polygons produced by the newer algorithm.  Is your polygon detail level is set to Detailed? Or do you have hierarchy turned on?  Either of those things will prevent the use of the newer algorithm in ArcMap. Do you have a polygon trim distance set?  If not, you should set one, and that may help reduce spikes. ... View more
