What is this tool?
Converts GTFS data, a common format for transit information, into network data.
Features
Uses stop information (stops.txt) and stop time information (stop_times.txt) to generate network data in CSV format.
1. stops.txt (used as node information)
| Variable | Description | Required | Usage |
|---|---|---|---|
stop_id | Stop ID | Yes | Used as node ID (source/target). |
stop_name | Stop name | Yes | Node name attribute. Also assigned as origin/destination names for links. |
stop_lat | Latitude | Yes | Node coordinates. |
stop_lon | Longitude | Yes | Node coordinates. |
2. stop_times.txt (used for link aggregation)
| Variable | Description | Required | Usage |
|---|---|---|---|
trip_id | Trip ID | Yes | Used for grouping to identify movements (A to B) within the same trip. |
stop_id | Stop ID | Yes | Identifies the source and target of each link. |
stop_sequence | Stop sequence | Yes | Determines travel order within a trip (used for sorting). |
arrival_time | Arrival time | Yes | Calculates link travel time (next stop arrival - current stop departure). |
departure_time | Departure time | Yes | Calculates link travel time. |
Output data attributes (aggregated/calculated values)
| CSV Header | Description | Calculation Method |
|---|---|---|
frequency | Number of trips | Count of trip_ids traversing the same segment (source to target). |
avg_duration_sec | Average travel time (seconds) | Average travel time for the same segment. |
How to use
- Upload GTFS files…Load the target files via drag-and-drop or file selection.
- Specify the current format…Select whether it is 1 file or 2 files.
- Press the convert button…
- After conversion, the file is automatically downloaded.
