The City Form Lab has released a free and open-source GIS toolbox for ArcGIS Pro for computing spatial accessibility via public transport using GTFS
data. The toolbox computes access from a given set of origin points to a given set of point destination points using a combination of walking and transit time within constraints chosen by the user. We can, for instance, measure access from homes (e.g. census block centroids) to jobs (e.g. establishment locations) at a particular time (e.g. 9AM on workdays), within a given time limit (e.g. 30 minutes) and within a maximum number of transfers (e.g. 2 transfers). Two different accessibility indices are available -- Reach and Gravity (see UNA user-guide for details). TeamKloe Ng,
