Network Analysis for Service Area and OD Cost Matrix

LonghaoGuo — Thu, 28 Aug 2025 19:07:28 GMT

Hello,

I'm currently working on a project about accessibility for healthcare centers. I need to use the Network Analysis function, such as Service Area and OD Cost Matrix. I think I have captured all the healthcare centers on the street, just like the population centroid. However, after running the Service Area function, it does not show me a polygon based on driving time.

I wonder if the Service Area can still display polygons based on driving time, or if it has been updated to a new tool? If I need to get the table of population centroid driving time to healthcare centers, which Network Analysis function or tool should I use?

Thank you for the help!

OD Cost Matrix is the best tool to use if you want a table showing the driving time of each population centroid to healthcare centers. Here's a tutorial: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/od-cost-matrix-tutorial.htm

Service Area should produce polygons around the provided facilities. If it's not working or producing the expected output, maybe something is wrong with the settings you chose or the network dataset you're using. (Did you create your own network dataset?)
