I have approximately 6000 locations in Port-Au-Price, Haiti with their coordinates. I need to calculate the distance matrix (real driving distances) for these location. I have street data from this link. I created a network dataset using this shape file. Before loading all locations to the OD Cost Matrix, I just selected 10 locations to verify to distances, initially. When I run the OD Cost Matrix, it doesn't give the full distance matrix. But I need to get the distances from all origins to all destinations. I think the primary problem is the quality of the road map I am using. I make the search tolerance 500 meters. You can see the attribute table and the lines below that I am getting. Could you please help me to create a full distance matrix for 6000 locations? I really appreciate any help you can provide on this. I have attached my data. Thank you.
