The question.
An itinerary can sound convincing while violating opening hours, travel times, traveler preferences, or the availability of actual services.
The expanded Travories concept treats itinerary generation as a constrained planning problem, with source freshness and alternative options visible to travelers.
The proposed approach.
- Maintain structured destination facts with source and freshness metadata
- Model trip time, geography, interests, and budget as explicit constraints
- Use agents to gather evidence and a deterministic validator to check the plan
- Present alternatives and seek confirmation before any booking action
Target architecture.
Travel briefDestination knowledgeRecommendationConstraint plannerItinerary validationTraveler review
The difficult parts.
- Sparse local information and stale availability
- Conflicting preferences and infeasible travel times
- Separating suggestions from confirmed reservations
How to evaluate it.
- Constraint satisfaction and factual itinerary accuracy
- Recommendation relevance on representative traveler briefs
- Planning latency and quality of alternative itineraries
Planned deliverables.
- A destination knowledge and itinerary schema
- A constraint-aware planning architecture
- A traveler-brief evaluation collection
Design principles.
A useful itinerary must be feasible before it is eloquent.
Keep recommendations distinct from confirmed bookings.
