Data Requirements

General Transit Feed Specification (GTFS)

RouteE-Transit relies on input data in the static GTFS format to generate energy predictions for each trip. Some features, such as complete shape traces for each trip, are optional per the GTFS standard but mandatory for RouteE-Transit analysis. In addition to all files and columns required by the GTFS standard, RouteE-Transit requires the following GTFS tables and fields:

• trips.txt: trip_id and shape_id for all trips

• shapes.txt: complete shape traces (shape_pt_lat, shape_pt_lon, shape_pt_sequence) for each trip

• stop_times.txt: all stop time data for each trip_id included

• stops.txt: stop coordinates for any stop served on any trip to be analyzed

Elevation Data

Road grade is computed automatically by RouteE-Compass using OSMnx to fetch elevation data from the USGS National Map. No manual download or configuration is required. For large geographic areas, the initial OSMnx network download may take additional time, but results are cached for subsequent runs.
