Skånetrafiken Trip Planner

Plan public transport journeys in Skåne, Sweden with real-time departure information.

Commands

1. Search Location

Search for stations, addresses, or points of interest.

./search-location.sh <query> [limit]

| Argument | Description |

|----------|-------------|

| query | Location name to search for |

| limit | Number of results to show (default: 3, max: 10) |

Output includes:

• ID - The location identifier (use this in journey search)
• Name - Official name of the location
• Type - STOP_AREA (station), ADDRESS, or POI (point of interest)
• Area - Region/municipality
• Coordinates - Latitude, longitude

When to increase limit:

• First result doesn't match user's intent
• User's query is ambiguous (e.g., "station", "centrum")
• Need to show user multiple options to choose from

2. Journey Search

Plan a journey between two locations using their IDs.

./journey.sh <from-id> <from-type> <to-id> <to-type> [datetime] [mode]

| Argument | Description |

|----------|-------------|

| from-id | Origin location ID (from search) or coordinates (lat#lon) |

| from-type | STOP_AREA, ADDRESS, POI, or LOCATION (for coordinates) |

| to-id | Destination location ID or coordinates |

| to-type | Type of destination |

| datetime | Optional: "18:30", "tomorrow 09:00", "2026-01-15 09:00" |

| mode | Optional: "depart" (default) or "arrive" |

Important: The Journey API only accepts STOP_AREA and LOCATION types. For ADDRESS or POI results, use the coordinates as lat#lon with type LOCATION.

Understanding User Time Intent

Before searching, understand what the user wants:

Intent Types

| User Says | Intent | How to Query |

|-----------|--------|--------------|

| "now", "next bus", "how do I get to" | Travel Now | No datetime parameter |

| "in 30 minutes", "in 1 hour", "after lunch" | Depart Later | Calculate time, use depart mode |

| "around 15:00", "sometime afternoon" | Around Time | Query with offset (see below) |

| "arrive by 18:00", "need to be there at 9" | Arrive By | Use arrive mode |

| "tomorrow morning", "on Friday at 10" | Future Time | Use specific datetime |

Handling "Around Time" Queries

When user wants options "around" a time, query 15-30 minutes earlier to show options before and after:

# User: "I want to travel around 15:00"
# Query at 14:30 to get options spanning 14:30-16:00+
./journey.sh ... "14:30" depart

Relative Time Calculations

Convert relative times to absolute:

| User Says | Current: 14:00 | Query Time |

|-----------|----------------|------------|

| "in 30m" | → | "14:30" |

| "in 1h" | → | "15:00" |

| "in 2 hours" | → | "16:00" |

🏁 Arrives ~15:25 (normally 15:17)

Walking Segment Details

CRITICAL: Always show walking details from the tool output:

• Distance in meters (from line.distance)
• Include walking in the "leave time" calculation
• Show walking at start AND end of journey

Example tool output:

→ WALK 450m from Kalendegatan to Möllevångstorget

Format as:

🚶 Walk 450m to Möllevångstorget (~5 min)

Walk time estimate: ~100m per minute (normal walking speed)

Presenting Multiple Options

When showing journey options, make timing crystal clear:

I found 3 options for you:

**Option 1 - Leave now (09:00)** ✅ Recommended
🚶 5 min walk → 🚌 Bus 5 at 09:07 → arrives 09:25
⏱️ Total: 25 min

**Option 2 - Leave in 15m (09:15)**
🚶 5 min walk → 🚌 Bus 5 at 09:22 → arrives 09:40
⏱️ Total: 25 min

LLM Workflow: How to Plan a Trip

Follow this workflow when a user asks for a trip:

Step 1: Understand Time Intent

Parse what the user wants:

• "How do I get to..." → Travel now
• "I need to be there at 18:00" → Arrive mode
• "Sometime around 3pm" → Query 14:30, show range
• "In about an hour" → Calculate from current time

Step 2: Search for Both Locations

Search for origin and destination separately:

./search-location.sh "Malmö C"
./search-location.sh "Emporia"

Step 3: Validate Search Results

Check each result carefully:

1. Exact or close match? - If the name matches what the user asked for, proceed.

1. Multiple results returned? - The script shows up to 10 matches. If the first result isn't clearly correct, ask the user to confirm.

1. Name significantly different? - If user asked for "the mall near Hyllie" and result shows "Emporia", confirm with user: "I found Emporia shopping center near Hyllie. Is this correct?"

1. No results found? - Try alternative strategies (see below).

Step 4: Handle Ambiguous or Failed Searches

When results don't match or are ambiguous, ask clarifying questions:

I searched for "centrum" and found multiple locations:
1. Malmö Centrum (bus stop)
2. Lund Centrum (bus stop)
3. Helsingborg Centrum (bus stop)

Which one did you mean?

When no results are found, try these strategies:

1. Try with city name for addresses:

# If "Storgatan 10" fails, try:
   ./search-location.sh "Storgatan 10, Malmö"

1. Try official station names:

# If "Malmö station" fails, try:
   ./search-location.sh "Malmö C"

1. Try landmark name only (without city):

# If "Emporia, Malmö" fails, try:
   ./search-location.sh "Emporia"

1. Use coordinates as last resort:

• If you know the approximate location, use lat#lon format directly
• Ask user: "I couldn't find that location. Can you provide the address or coordinates?"

Step 5: Convert Types for Journey API

The Journey API only accepts:

• STOP_AREA - Bus/train stations (use ID directly)
• LOCATION - GPS coordinates as lat#lon

If search returns ADDRESS or POI:

• Use the coordinates from search result
• Format as lat#lon with type LOCATION

Example:

# Search returns: ID: 123, Type: ADDRESS, Coordinates: 55.605, 13.003
# Use in journey as:
./journey.sh "55.605#13.003" LOCATION 9021012080000000 STOP_AREA

Step 6: Execute Journey Search

Once you have confirmed IDs/coordinates for both locations:

./journey.sh <from-id> <from-type> <to-id> <to-type> [datetime] [mode]

Step 7: Format Response with Emojis

Use the emoji guide above to present results clearly. Always use actual numbers from the tool output - never speculate or estimate.

---

Query Formatting Rules

The search API is sensitive to formatting. Follow these rules:

Landmarks and POIs: Name Only

Use the landmark name WITHOUT city name.

# CORRECT
./search-location.sh "Emporia"
./search-location.sh "Triangeln"
./search-location.sh "Turning Torso"

# WRONG - city name breaks POI search
./search-location.sh "Emporia, Malmö"        # May return wrong location!
./search-location.sh "Triangeln, Malmö"      # Unnecessary, may fail

Street Addresses: Include City

Include city name for better accuracy.

# CORRECT
./search-location.sh "Kalendegatan 12, Malmö"
./search-location.sh "Storgatan 25, Lund"
./search-location.sh "Drottninggatan 5, Helsingborg"

# RISKY - may be ambiguous
./search-location.sh "Kalendegatan 12"       # Works if unambiguous

Train Stations: Use Official Names

Use "C" suffix for central stations.

# CORRECT
./search-location.sh "Malmö C"
./search-location.sh "Lund C"
./search-location.sh "Helsingborg C"
./search-location.sh "Malmö Hyllie"
./search-location.sh "Malmö Triangeln"

# WRONG
./search-location.sh "Malmö"                 # Ambiguous!
./search-location.sh "Malmö Central"         # Not official name
./search-location.sh "Lund station"          # Not official name

Copenhagen (Cross-border)

Use Danish names or common alternatives.

# All work
./search-location.sh "København H"
./search-location.sh "Nørreport"
./search-location.sh "Copenhagen Airport"
./search-location.sh "Köpenhamn"

When to Ask Clarifying Questions

Always ask when:

1. Search returns no results:

• "I couldn't find [location]. Could you provide more details like the full address or nearby landmarks?"

1. Multiple plausible matches:

• "I found several locations matching '[query]': [list]. Which one did you mean?"

1. Result name very different from query:

• "You asked for '[user query]' but the closest match I found is '[result name]'. Is this correct?"

1. User request is vague:

• "From Malmö" - "Which location in Malmö? The central station (Malmö C), or a specific address?"

1. Cross-border ambiguity:

• "Copenhagen" could mean different stations - confirm if they want København H (central), Airport, or another station.

1. Time is unclear:

• "When do you want to travel? Now, or at a specific time?"
