Lviv Public Transport

Lists the routes from one place to another: which stop to board, where to get off, the direction's destination, stops in between, and the walk at each end — best first, walking counted. `options` are direct routes. `transfer_options` have exactly one interchange (never more): ride `legs[0]`, walk `transfer_walk_meters` (within a 300 m stop cluster, 0 when it is the same stop) to `legs[1].board_stop`, ride `legs[1]`. They are listed when there is no direct route or when they beat the best direct one. `map_stops` holds the best trip's stops in riding order, each with a `role` (board, transfer — or transfer_alight + transfer_board when the interchange is a walk — and alight). Use when the user asks how to get from A to B, or which bus/tram goes from one place to another. Each end covers every stop within a 300 m walk of the one given, since a line's two directions often stop on opposite sides of a street under different names; `board_stop` says where to actually wait. Both lists empty means the trip needs two or more transfers. Requires numeric stop IDs; get them with `search_stops` or `get_stops_around_location` first. Follow up with `get_stop_realtime` on `board_stop` for live departures.

Returns live vehicles near a point, nearest first, each with its route, destination, and distance. Use when the user asks "what transport is near me right now?" or wants a live map around a location. Narrow with `route` when the user cares about one line; prefer `get_route_realtime` for a whole route and `get_stop_realtime` for arrival times at a stop. Requires decimal latitude and longitude (WGS84).

Returns every vehicle currently running on a route: position, the destination it is heading to, and its next stop with estimated arrival. Use when the user asks "where is my tram/bus right now?", how many vehicles are running, or how far the next one is. Prefer `get_stop_realtime` when the user is at a stop and wants arrival times there. Requires a route short name (e.g. "T30", "32A") or numeric external ID.

Returns static route data: name, long name, vehicle type, colour, the ordered stop list for both directions, and the timetable of departures from the first stop (workday, Saturday and Sunday). Use when the user asks which stops a route serves, where it goes, or its scheduled departure times. Set `include_shapes` only when you will draw the route on a map — the polylines are large and carry nothing a text answer needs. Do NOT use this for live vehicle positions — use `get_route_realtime` instead. Requires a route short name (e.g. "T30", "32A") or numeric external ID.

Returns live arrivals at a stop: route, destination, vehicle type, minutes until arrival, and each vehicle's position. Use this as the **default tool** when the user asks about arrivals, departures, or the next bus/tram at a specific stop. Requires a numeric stop ID (shown on stop signage); use `search_stops` when you have a stop name, or `get_stops_around_location` when you have coordinates.

Finds stops near a geographic point, returning each stop's numeric ID, name, coordinates, walking distance, and the routes serving it. Use this as the **first step** when the user gives an address or coordinates and you need stop IDs for `get_stop_realtime` or `find_routes_between`. Use `search_stops` instead when the user gives a stop name. Default radius is 1 000 m; narrow it (e.g. 300 m) for dense urban areas or widen it (up to 3 000 m) for rural locations.

Returns details for one vehicle by ID: position, route, destination, license plate, and its upcoming stops with names and estimated arrival times. Use when the user wants to follow a particular vehicle, e.g. "where does this tram go next?" or "when will it reach X?". Vehicle IDs come from `get_route_realtime`, `get_nearby_vehicles`, or `get_stop_realtime` results. Do NOT use this to get all vehicles on a route — use `get_route_realtime` instead.

Finds stops by name (Ukrainian or English transliteration, case-insensitive, partial match) and returns each stop's numeric ID, coordinates, and the routes serving it. Use this as the **first step** when the user names a stop or landmark stop (e.g. "Опера", "Rynok", "Головний вокзал") and you need a stop ID for `get_stop_realtime` or `find_routes_between`. One name usually covers both sides of the street under different IDs; each is returned, and the `routes` list tells them apart. Use `get_stops_around_location` instead when you have coordinates rather than a name.
