The Interpolate Blank Stop Times toolset is a utility for estimating arrival_time and departure_time values that have been left blank in the stop_times.txt GTFS file. Values for arrival_time and departure_time are required for certain types of analysis.


  • Updates your stop_times.txt file with estimated arrival_time and departure_time values for any entries which are blank.
  • ArcGIS toolbox - No coding is required to use this tool. Just add the toolbox to ArcMap and use the tools like any other geoprocessing tools.


  1. To simply use the tool, download the latest release and follow the included User's Guide.
  2. If you want to play with the code, fork it and have fun.


  • ArcGIS 10.0 or higher with a Desktop Basic (ArcView) license, or ArcGIS Pro
  • A valid GTFS stop_times.txt file
