trafiklab_service_tracker
This tool fetches information about current journeys of a given transit route using the TrafikLab APIs. The data is only available for Stockholm, Sweden. The script checks the expected and actual time of departure/arrival by stop, for all the current journeys of the route. When each journey finishes, its final values are appended to a CSV file. The script tries to make the least number of requests, with five retries at most in case of error.
