How can I calculate the distance from each student’s home to their assigned school to determine if they’re eligible to ride the school bus? How can I calculate the commute time from each employee’s home to their work site so I can most effectively target ridesharing incentives? How can I calculate the driving time from each patient’s home to the location of their doctor’s appointment to better understand access to health care in my state?<\/p>\n

All these questions are examples of a common class of network analysis problem: calculating the travel time, distance, or route path between preassigned pairs of origins and destinations.<\/p>\n

In this type of analysis, the goal isn’t to find the closest destination (a closest facility analysis) or to calculate the travel time or distance from all origins to all destinations (an origin destination cost matrix analysis). Nor is the goal to find the optimal way to dispatch a fleet of vehicles for paired pick-ups and drop-offs (a vehicle routing problem analysis). Rather, the goal is to calculate the optimal path from each origin to its assigned destination and get the travel time, distance, or route geometry of that path. This type of problem can be solved using the Network Analyst route solver. <\/p>\n

As long as you set up the problem correctly, the Network Analyst route solver can calculate routes between multiple pairs of locations within one solve operation.<\/p>\n

The input to the route solver is a single table of stops. Ordinarily, when you solve the analysis, you get a single route that visits all the stops in the table.<\/p>\n

To load the Stops table from the original inputs, you have to do a bit of data manipulation.<\/p>\n

When loading the commuters, you can use field mapping to transfer the commuter’s name from the original dataset to the Name and RouteName fields in Stops. In ArcGIS Pro, this is accomplished using the Add Locations<\/a> tool.<\/p>\n

Loading the work sites is trickier because you must make a copy of each work site for each commuter who works there. You can do this using a one-to-many join with the Add Join<\/a> tool.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2457352,"id":2457352,"title":"AddJoin","filename":"AddJoin.png","filesize":17561,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/network-analyst\/transportation\/paired-origins-and-destinations\/addjoin-3","alt":"The one-to-many join option in the Add Join tool","author":"6101","description":"","caption":"","name":"addjoin-3","status":"inherit","uploaded_to":2457182,"date":"2024-08-12 16:07:57","modified":"2024-08-12 16:08:06","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":329,"height":424,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","medium-width":203,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","medium_large-width":329,"medium_large-height":424,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","large-width":329,"large-height":424,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","1536x1536-width":329,"1536x1536-height":424,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","2048x2048-width":329,"2048x2048-height":424,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","card_image-width":329,"card_image-height":424,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/AddJoin.png","wide_image-width":329,"wide_image-height":424}},"image_position":"left-center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Ready-to-use tools to solve preassigned origin-destination pair problems<\/h2>\n

Manually configuring your data in the format described above can be challenging. However, ready-to-use tools for solving preassigned origin-destination pair problems are available in the Map Viewer and ArcGIS Pro. These tools use the route solver, but they simplify setting up the inputs.<\/p>\n

Solve preassigned origin-destination pair problems in Map Viewer<\/h3>\n

The Calculate Travel Cost<\/a> tool in Map Viewer in ArcGIS Online and ArcGIS Enterprise is specifically designed to calculate routes between origins and destinations. You can specify matching ID fields in the input origins and destinations to define which origin is paired with which destination.<\/p>\n

If you’re a developer, you can also access this tool with ArcGIS REST API<\/a> and ArcGIS API for Python<\/a>.<\/p>\n

Solve large preassigned origin-destination pair problems in ArcGIS Pro<\/h3>\n

If you have a large set of paired locations or you’re struggling to set up your data as described above, you can download and use the Solve Large Analysis With Known OD Pairs tool from Esri’s large-network-analysis-tools GitHub repository<\/a>.<\/p>\n

This tool offers two options for setting up pairs of input locations:<\/p>\n

    \n
  1. A field in the origins table defines the assigned destination (one-to-one).<\/li>\n
  2. A separate table defines the origin-destination pairs (many-to-many).<\/li>\n<\/ol>\n

    The tool improves performance by solving the routes in parallel. It’s usable out of the box in ArcGIS Pro with no coding required, but it’s also open-source Python code you can modify to suit your needs.<\/p>\n"},{"acf_fc_layout":"content","content":"

    Conclusion<\/h2>\n

    You can calculate the travel time, distance, and route paths between paired locations using the ArcGIS Network Analyst route solver. You can configure the analysis manually, or you can use ready-to-use tools in the Map Viewer or ArcGIS Pro. Give it a try!<\/p>\n

    If you have questions or suggestions about this workflow, reach out on Esri Community<\/a>. We would love to hear from you!<\/p>\n"}],"related_articles":"","card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/08\/CardImage.png","wide_image":false},"yoast_head":"\nCalculate
