Implementation Reference

• src/modules/traffic.ts:164-182 (handler)

  The handler implementation for the 'get_traffic_by_canton' tool, which processes the request, calls the ASTRA API, and formats the output.

  case "get_traffic_by_canton": {
    const canton = (args.canton as string).toUpperCase();
    const url = buildUrl(`${GEO_ADMIN}/find`, {
      layer: TRAFFIC_LAYER,
      searchText: canton,
      searchField: "canton",
      returnGeometry: false,
    });
    const data = await fetchJSON<FindResponse>(url);
    const stations = data.results.slice(0, 20).map(slimTrafficStation);
    return JSON.stringify({
      count: stations.length,
      total: data.results.length,
      canton,
      stations,
      source: "ASTRA — Federal Roads Office (Bundesamt für Strassen)",
    });
  }
