I'm trying to calculate a distance and time for walking commuters (about 30,000 records) on a street network (NYC Lion). I have a starting and ending address for each record that have been geocoded. As far as I know I don't have an ArcGIS Network Analyst extension license at the moment (maybe there's a free trial?) so I'm curious if anyone knows how to do this without Network Analyst. I have QGIS but I'm not sure if you can batch process records in this capacity.
Try the Urban Network Analysis toolbox download from City Form Lab.
