Mapping Transit System Coverage

[@kyarisiimaflorence4449]

I have a question about the facilities, what if i want to know the accessibility from the transit stops to the different social amenities for example schools, health facilities, places of worship. How do i specify this in the service area analysis. I would like to know for example areas within a 5, 10, 15, 20 minute drive from the bus stops. So that at the end of this, i know places that are accessible and those are not from the bus stop.

One option is to do a spatial join or other overlay analysis with the Service Area polygons and your points of interest/amenities. However, since the shape of the Service Area polygons depends heavily on the polygon generation settings you use, this method isn't completely accurate. A better option is to use an OD Cost Matrix analysis using the bus stops as destinations and the amenities as origins. You can configure it to find only destinations within a 5, 10, or 15-minute walk time, or you can post-process the results to get the same information. You can also configure it to find only the closest bus stop to each amenity or to find all of them within the walk time limit. Here is a tutorial where you can learn how to do an OD Cost Matrix analysis: pro.arcgis.com/en/pro-app/latest/help/analysis/networks/od-cost-matrix-tutorial.htm

please what Windows app are you currently using to program this data in the video?

When you test this in ArcPro I get an error that: The maximum records for Facilities limit of 1,000 has been exceeded. Maybe show us how to overcome that error. Do we need more credits?

[@esri_arcgis]

The ArcGIS Online services have hard limits on the number of inputs that can be used in a single analysis. These limits are to prevent the servers from being overloaded or tied up for other users, and it is not related to the number of credits you have available. If you want to use the ArcGIS Online services for your analysis, you will need to split up the Service Area into multiple chunks with

Can you please do a video on the best way to split my network facilities into chunks? I am having the same error of exceeding the 1000 facilities limit

You can find a video of a presentation from DevSummit 2022 about solving large network analysis problems here: mediaspace.esri.com/media/t/1_hzppnv8p. I’m not sure this will be completely applicable to your question, which may be a lot simpler than the topic of the presentation, but it may be of some interest. To split your inputs manually, you can essentially just select groups of 1000 and call Add Locations, which will obey the selection set. When the layer finishes solving, export the polygons. Then merge all the polygons into one feature class after all groups have been completed. KZbin comments aren’t a great way to provide tech support, so if you have further questions, you should either reach out to Esri Support or the distributor for your country or post a question on the Esri Community in the Network Analyst section: community.esri.com/t5/arcgis-network-analyst-questions/bd-p/arcgis-network-analyst-questions

Where can I find Routing_ND in you example ?

[@esri_arcgis]

I can't share the Routing_ND network dataset used in this example. It is Streetmap Premium data which you can purchase from Esri for your area of interest. The video describes several options for creating or acquiring a network dataset from 5:52-7:05. The slides have links in them, and you can download the slides using the link under the video.

Will it work if i have shape file of all roads instead of Open streets data sets?

[@esri_arcgis]

You can use any good quality dataset of street features to create a network dataset. The streets must be well connected at intersections and contain sufficient attributes to calculate travel speeds and any restrictions you care about. Note that if your data is in a shapefile format, you will have to export it into a file geodatabase feature class before you can use it to create a network dataset. Here is a tutorial: pro.arcgis.com/en/pro-app/latest/help/analysis/networks/how-to-create-a-usable-network-dataset.htm.

[@genchoxha1779]

Can you converst your transit lines to network dataset, so you dont need to have streetmaps premium?

[@esri_arcgis]

No. To properly model walking and transit, you need an additional, separate dataset that includes streets. Otherwise, the traveler will not be able to walk to and from transit stops or make transfers that don’t share the same stop. You don’t need Streetmap Premium for this, though. You can use any good quality street dataset. If you don’t have anything from your local government or another data vendor, you can use OpenStreetMap.
