amarillo-stops

Carpool stop import library with shared code for Amarillo GTFS-generator and Enhancer. Provides stop import functions in multiple formats and the StopsStore class with a couple of function to manage and query the stops.

Supported import formats

Import stops from:

.csv:

Example format:

stop_id;stop_code;stop_lat;stop_lon;stop_name
mfdz:x;x;52.11901;14.2;Stop x
mfdz:y;y;53.1;14.01;Stop y
mfdz:z;z;54.11;14.0;Stop z
mfdz:Ang001;Ang001;53.11901;14.015776;Mitfahrbank Biesenbrow

GeoJSON:

Example format:

{
  "data": {
    "pointsOfInterest": [
      {
        "id": "14622",
        "externalId": "bbnavi:12073:0001",

}

Overpass

Makes a request to https://overpass-api.de/api/interpreter with the query below and imports the result:

[out:csv(::"type", ::"id", ::"lat", ::"lon", name,parking,park_ride,operator,access,lit,fee,capacity,"capacity:disabled",supervised,surface,covered,maxstay,opening_hours)][timeout:60];
area{area_selector}->.a;
nwr(area.a)[park_ride][park_ride!=no][access!=customers];
out center;

GTFS

Opens stops.txt inside the zip file and imports it as .csv

StopsStore class

Constructor parameters:

  • stop_sources: array of stop source urls. Can point to local or remote resources. vicinity controls how far from the trip path they can still be associated with a trip. Example:
[
    {"url": "https://datahub.bbnavi.de/export/rideshare_points.geojson", "vicinity": 50},
    {"url": "https://data.mfdz.de/mfdz/stops/stops_zhv.csv", "vicinity": 50},
    {"url": "https://data.mfdz.de/mfdz/stops/parkings_osm.csv", "vicinity": 500}
]
  • internal_projection: optionally override the used projection. Default value is EPSG:32632.

load_stop_sources(self): Imports stops from stop_sources and registers them with the distance they are still associated with a trip. E.g. bus stops should be registered with a distance of e.g. 30m, while larger carpool parkings might be registered with e.g. 500m.

Subsequent calls of load_stop_sources will reload all stop_sources but replace the current stops only if all stops could be loaded successfully.

find_additional_stops_around(self, line, stops): Returns a GeoDataFrame with all stops in vicinity of the given line, sorted by distance from origin of the line. Note: for internal projection/distance calculations, the lat/lon geometries of line and stops are converted to

find_closest_stop(self, carpool_stop, max_search_distance): Returns the closest stop to the given carpool stop, searching within the max_search_distance
