I created buffers of 1km around individual grocery store facilities (purple dot symbol). However, within some buffer zones, there are also market fairs and informal street vendors (represented by orange dots and green triangle symbols respectively). I cannot figure out how to manage this "conflicting issue" of having other facilities within the same buffer since the buffer rings are supposed to be for the grocery stores. I wanted to solve the issue described above so that I can use each buffer to calculate the Euclidean and Manhattan distances from the residential area (represented by pale green color) polygon centroids to each of the 3 types of facilities using their coordinates and tabulating in excel. Can anyone help me out?

Thank you for your kind response. I tried the different options that you suggested. However, after checking for connectivity, I still cannot resolve the problem of getting lines to connect the origins (street nodes) to the destinations (schools) using the OD cost tool. Do you think that the school locations should absolutely be found on the road network itself? Do you have any other suggestions to help me out? I would be open to use other tools to analyze walkability in the case that I cannot use the road network as input. Anyone who could kindly contribute is also welcomed, thanks. Yannick

Dear all, I have read about different posts on "OD cost matrix : Not all lines solved" but I still cannot figure out some issues in my case. I wanted to get lines from street nodes (blue dots as origin) to grocery stores (blue squares as destination) within individual service areas. Although I checked and cleaned the street network to remove errors (dangles and pseudo nodes), I get only 1-2 lines that appear for each destination after solving the OD cost. I wanted to get all nodes to connect to the grocery store within a particular service area. I tried to play around with the settings changing the connectivity from "end-point" to "any vertex" and tried to re-run several times but still no good.Each time, I get a message saying "Warning: No "Destinations" found for "Location 1" in "Origins". I get a list for all of these locations. I attached a sample of the issue I am having. Can anyone help me out? I would really appreciate.
